By using this cutting edge procedure, your pet will enjoy full functioning joints and tissues no matter their age. Her main research work career has been in cell and molecular biology of various inherited diseases. Roberts held an Associate Professor position at the University of Virginia where she pursued interdisciplinary research in the area of immunity and inflammation. MSCs can generate multiple mesoderm-type cell lineages, such as osteocytes, chondrocytes, adipocytes, myocytes, tenocytes, and stromal cells1.2. Since 2006, she has been an Adjunct Professor of Biochemistry for the University of Helsinki.Dr. These cells, originally designated stromal cells, elicited much attention, and the main goal of thousands of studies conducted using these cells was to find an ultimate pure cell population that could be further utilized for regenerative purposes. In these studies, cells were isolated using several methods and were given names such as mesenchymal stem cells (MSCs), mesenchymal progenitors, stromal stem cells, among others.
Lately, a committee of the International Society for Cytotherapy suggested the name “multipotent mesenchymal stromal cells” (Dominici et al., 2006). However, most scientists have been referring to them simply as “MSCs”.The precise definition of these cells remains a matter of debate. 1).As part of their stem cell nature, MSCs proliferate and give rise to daughter cells that have the same pattern of gene expression and phenotype and, therefore, maintain the “stemness” of the original cells. MSCs can generate multiple mesoderm-type cell lineages, such as osteocytes, chondrocytes, adipocytes, myocytes, tenocytes, and stromal cellsIn contrast to other stem cells such as hematopoietic stem cells (HCSs), which are identified by the expression of the CD34 surface marker, MSCs lack a unique marker. The CD105 surface antigen (endoglin) has been recently used to isolate human MSCs (hMSCs) from BM and such an approach enabled the characterization of freshly isolated hMSCs before culture. A distinct expression of certain surface antigens such as CD31 and CD45 was demonstrated in freshly isolated hMSCs and the expression of these molecules was lower in culture-expanded hMSCs (Aslan et al., 2006). The stem cell nature of MSCsStem cells are defined by their ability to self-renew and by their potential to undergo differentiation into functional cells under the right conditions.

The ongoing public discussion regarding whether MSCs are strictly stem cells requires a revision of the definition of stem cells, as MSCs apply to a wide cluster of non-hematopoietic stem-like cells isolated from mesenchymal tissues such as BM, adipose, amniotic fluid, and blood vessels.
The central question would be whether they might be differentiated into cells of other than a mesenchymal nature. As stated above, there is a consensus on specific MSC markers, but a unique marker of “stemness” and multipotentiality has not yet been defined, since culture-expanded MSCs may lose some of these markers and acquire others, which are non-specific, but cells retain their multipotentiality (Jones & McGonable, 2008). The results of these studies demonstrate the multilineage differentitation potential of BM-derived adult MSCs and aid in defining them as suitable candidates for the regeneration of several mesenchymal tissues. These data suggest that stem cells require a specific tissue environment to develop their intrinsic potency (Weissman, 2000). A stem cell niche is defined as a complex, multifactorial local microenvironment required for the maintenance of the stem cell biology. The stem cell niche consists of stem cells, non-stem cells, an extracellular matrix (ECM) and molecular signals.
Inside the niche, the stem cell can divide asymmetrically giving rise to both new stem cells and proliferating progenitor cells.
These proliferating cells give rise to a cell population that undergoes differentiation (Becerra et al., 2011).
Recent scientific advances have lead to a substantial increase in the amount of information regarding stem cell niche data. MSCs and tissue engineeringThe chronic shortage of donor organs and tissues for donor organs and tissues for transplantation has provided the impetus for intense research in the field of tissue engineering (TE). Unlike pharmacology and physiotherapies they are mainly palliative, TE and cellular therapy seek to augment, replace, or reconstruct damage of diseased tissues (Chai & Leong, 2007). Tissue engineering is an emerging field that offers outstanding opportunities for regenerative medicine. The scaffold supports cell colonization, migration, growth and differentiation, and often guides the development of the required tissue or acts as a drug delivering vehicle. EditionThe right knowledge of these interactions will create exciting new opportunities that might be useful in a broad array of clinical applications.
As a logic consequence, today, a great number of multi-disciplinary groups with different backgrounds (Fig.
EditionMoreover, it has been described that growth factors (GFs) can act by an autocrine, paracrine, endocrine, juxtacrine, ECM mediated or intracrine process (Fig. Some experiments have suggested that this interaction may even occur within the cell, a process called intracrine interaction (6).
Paracrine action is defined as the release of soluble GFs which diffuse into the extracellular space and act upon adjacent or closely located cells (2). In the case of endocrine action, GFs are carried in the bloodstream and may act on distant sites much like a hormone (3). Juxtacrine stimulation is when one cell has surface bound GFs which interact with an adjacent cell containing receptors for the GF (4). They also regulate events in normal embryonic development, angiogenesis, wound repair, and cell differentiation. FGFs are involved in endothelial cell proliferation and the physical organization of endothelial cells into tube-like structures.
Moreover, FGFs are important players in wound repair, stimulating the proliferation of fibroblasts that give rise to granulation tissue, which fills up a wound cavity early in the wound healing process (Schmid et al., 2009).
The anti-fibrotic effects of MSCs have been demonstrated in different animal models, but the molecular mechanisms are not yet fully understood. Recently, HGF has been shown to be involved in the prevention of fibrosis (Li et al., 2009). The results reveal that, in a situation of tissue injury, MSCs become proliferative and secrete HGF, which in turn mediates anti-fibrotic and immunomodulatory effects.
Additionally, the secretion of HGF and IGF-I is essential for activation of cardiac stem cells, which may contribute to endogenous repair mechanisms (Linke et al., 2005).
On the other hand, IGFs play an important role in stem cell maintenance within the niche (Bendall et al., 2007), and bone metabolism.
During osteogenesis, bone cells secrete amounts of IGFs that are stored at the highest concentration of all GFs in the bone matrix (Wang et al., 2011). The main functions of PDGF are to stimulate cell replication of healing capable stem cells, as well as proliferation of endothelial cells. This will cause budding of new capillaries into the wound (angiogenesis), a fundamental part of all wound healing. Additionally, MSCs also express various neuro-regulatory proteins, adhesion molecules and receptors that likely contribute to the MSC-induced effects on neuronal cell survival and neurite formation (Crigler et al., 2006). Another family of proteins critical in MSC biology is the Wnt family of signalling molecules (Ling et al., 2009).
Wnts are highly conserved proteins that are essential to limb development and musculoskeletal morphogenesis in vertebrates (Yang, 2003). At least Wnts 2, 4, 5a, 11 and 16 are expressed by MSCs along with several Wnt receptors (Frizzleds 2-6) (Etheridge et al., 2004).
By learning more about the mechanisms of action and interactions of each member of this microenvironment, it will be possible to develop the full potential of MSCs for future therapeutic applications.2.
Therapy for bone fractures and arthrodesisThe treatment aim of bone fractures and of many orthopaedic deformities is the fusion between two or more bone ends or bone structures. Therapy for diaphyseal, metaphyseal or paraarticular fractures of long or short bones, either simple or complex, is always addressed to achieve permanent solid bone continuity between fractured bone fragments. Nowadays surgical treatment of these conditions is the choice for both young and old patients, as conservative treatment requires prolonged neighbor joints rest which results in articular stiffness and unacceptable deformities. Further, in many instances, non-surgical treatment will be unsuccessful in dealing with many low or high energy fractures, and also with orthopaedic corrections as non-union or malunion will occur.Current surgical treatment of fractures or orthopaedic deformities aimed to promote osteogenesis for bony fusion is still far away from being undoubtedly successful. Surgical site infection, implant failure, and many other complications will facilitate failure of achieving the main aim of surgical treatment. Nonetheless, diaphyseal non-unions and even paraarticular ones, although in some cases present difficult challenges to bony union, can be managed, at least, under favorable biomechanical situations; further, its biology can be managed with autograft.
Conversely, since in spinal fusion the size of any vertebra and the distance to each other make the biomechanical and biological situation very difficult for addressing a successful treatment of fusion or non-union, current and forthcoming new “biological” therapies have important perspectives. In relation to bone therapy, spinal fusion is currently the most significant surgical technique expecting for progress in biological treatments.Surgical technique of spinal arthrodesis combines a hardware system for mechanical stabilization and a biological substance for bone formation enhancement. Using the same graft, either cortical or cancellous, different placements may need different nature of osteosynthesis, and may make the own graft behaves in different ways. Therefore, only when correct stabilization has been performed, as in any fracture treatment, biology behaves in the wished way.
Likewise provided biomechanics is correct, the same graft behaves in different ways depending on the biomechanical forces acting on it (Guerado et al., 2005). The three main properties a therapy for optimum fusion enhacement must have are osteogenesis, osteoconduction, and osteoinduction, together with avoidance of histoincompatibility, and, in the clinical setting, as said above, a favorable biomechanical situation (Boatright & Boden, 2002). Osteogenesis consists basically on cells differentiation into osteogenic linage, being bone cells the only agent with osteogenetic power.

Osteoconduction is also the complement to osteogenesis and osteoinduction; a tridimensional scaffold structure of bone or bone substitute is an indispensable scaffolding for cell population growth. An osteoconductive microstructure of 200-400 microns is nowadays very easy to be manufactured. However osteoinductive GFs doses to be added to it are unknown; further osteogenetic properties of “bone substitutes” are lacking for osteoconductive materials, as osteogenesis is an exclusive property of mature osteoprogenitor cells.
Since bone synthesis is exclusively made by bone cells, a large population of osteoprogenitor cells is necessary for successful fracture or spinal fusion.
Because MSCs population is very scarce in elderly people, this age group has a higher risk for non-union (Caplan, 1991).
Hence clinical situations lacking of any of these variables are in less than optimal condition for successful spinal fusion. The relation between biomechanics and biology in spinal surgeryAutograft is the standard biological agent to be added in fracture or arthrodesis focus for bone repair enhancement (Figs. Autograft is also the standard for spinal arthrodesis as the natural source of osteoprogenitor cells (Fig. It can be used in spinal surgery either as cancellous chips or as a tricortical alive implant in order to improve the immediate strength of the construct. C6-C7 interbody disc has been removed for interbody fusion by a tricortical autograft harvested from iliac crestThis basic knowledge on autograft has been achieved after animal experiments, making clinical inference to human very uncertain. Cancellous bone graft has greater cellular activity than cortical, whereas cortical graft is much more dense and stronger (Day et al., 2000). Spongy structure of cancellous bone allows osteoprogenitor cells to have better vascularization, developing superior osteoconduction and osteogenesis. Anyhow although histological incorporation with prompt vascularization and MSCs invasion stars at the second day of implantation, mechanical properties of cancellous bone are compromised during remodelation phase, taking a few months to become structurally stronger (Pape et al., 2010). 5-8); however in clinical setting it is usually preferred, by some surgeons, a 360? fusion, as surgeons feel more confident in case of implant failure.
Eventually, during the course of thoracotomy, removed ribs for anterolateral thoracic or thoracolumbar approaches can substitute the use of tricortical grafts, suppressing the morbidity provoked by iliac crest graft harvesting. Therapy with laboratory treated MSCsMany studies have been made during the last years in experimental MSCs application for therapy in animals. Stem cells are currently being studied for use in numerous clinical applications, ranging from neurodegenerative diseases to cardiac insufficiency. The use of MSCs in spinal surgery is also compelling, especially with the increasing age of the general population.
In spinal surgery, the use of MSCs is focused in intervertebral disc repair and regeneration and in spinal arthrodesis procedures. The mechanism was likely to be mediated through better osteointegration between the host bone and implanted materials and enhanced endochondral ossification at the fusion site (Hui et al., 2011). However it is known that osteogenesis in spinal rabbit is achieved just by stripping the periostium. Also MSCs that had been cultured with osteogenic differentiation medium may induce the formation of new bone in experimental posterolateral intertransverse process spinal fusion in rabbits. It has been shown that MSCs and platelet lysate seeded in a fibrin or collagen scaffold can improve the new bone formation around an uncemented hip prosthesis stem in a sheep model. In vitro expanded MSCs suspended in platelet lysate and either mixed with collagen or fibrin gel as delivery vehicle inserted inside the femoral canal, in a press-fit femoral stem model provides higher bone-prosthesis contact (Dozza et al., 2011). But again biology is subjected to biomechanics and human and animal hip biomechanics are not similar.MSCs transplantation will be a very important therapeutic principle, however deep knowledge not only on cells in cultures but also in biomechanical situations resembling clinical setting is needed. Cartilage regenerationDegenerative disease of articular cartilage (AC), generically known as osteoarthritis (OA), is an irreversible evolution process towards terminal articular failure. Due to its high prevalence on population and its socioeconomic impact, this condition is of great concern, and this way more resources and effort are dedicated to the research on its development.OA is the result of several mechanical changes and biological events that destabilize the balance between normal degradation and synthesis of AC, ECM and subchondral bone.
It is made up of one ECM with proteoglycan, rich in type II collagen, and about only 5% of the tissue volume occupied by cells. These cells, the chondrocytes, are spherical, and can be found embedded inside lacunae filled with pericellular matrix and have no contact with the distant neighbour cells. Although human cartilage can reach up to 7-8 mm thickness, its supply with nutrients and oxygen is limited by diffusion, which is, however, facilitated by a cyclic compressive loading; this provides a pumping mechanism during joint movements.
There are several reasons that contribute to a lessened capacity of response from chondrocytes before an injury regarding other parenchymal cells. As it has no vascularisation, the typical provisional matrices made from fibrin deposits do not exist, nor the inflammatory cells afflux occurs, there is no delivery to the environment of cell mediators through degranulation, whereas in other tissues, arrival to the focus of such mediators with mitogenic, fibrogenic and phagocytosis-inducing capacities are responsible for the repair. Although most of the actions promoted by the mediators of inflammation can enhance the injury magnitude (such as the proteolythic capacity, free radicals production, cell death or proliferation), the best guarantee for the restitutio ad integrum is its early delivery at the injured focus.Chondrocytes are well differentiated cells with a limited proliferative and migratory capacity. A macroscopic structural injury involves higher demand of matrix synthesis, resulting in an insufficient cell response to achieve the tissue regeneration. However, the regenerative capacity of the organs lies on the persistence of cell progenitors in some areas of the adult tissues. Mesenchymal non-differentiated cells found in the AC prove that cartilage, as other tissues, has the capacity to regenerate its own structure.
This suggests the existence of a lapse of time in which the capacity or repair is complete; this period would possibly cover the early stages of the disease when defects are microscopic.
The most adequate resolution of a chondral defect should involve the regeneration into a tissue identical to hyaline cartilage.
A simple repair means the filling with a non-identical tissue, which should be able to seal the defective area with good adhesiveness to subchondral bone and total integration within the surrounding cartilage, as well as to resist the mechanic wear and incorporate into the natural turnover of the normal tissue.All this makes the AC a tissue with almost no healing capacity for intrinsic healing in most in vivo situations, although tissue culture demonstrates that in vitro conditions may reactivate a significant regenerative potential for juvenile tissue and articular chondrocytes. In partial cartilage defects, the subchondral plate remains intact, without access to the vascular system and they are not usually repaired spontaneously. On the other hand, defects that penetrate the full chondral thickness are generally associated to the violation of the subchondral plate, thus exposing the defect to the vascular system though the marrow area. This leads to the migration of MSCs to the damaged area, where they undergo the chondrogenic differentiation. Nonetheless, in many instances the repair tissue is made up of fibrocartilage that contains mainly collagen type I fibres, and does not meet the criteria precise for a functional tissue. Small defects can be repaired spontaneously with hyaline cartilage production, whereas larger defects will only be able to be repaired with the production of fibrous or fibrocartilaginous tissue, which are biomechanically and biochemically different from the normal hyaline cartilage.
As a result, degeneration subsequently appears which can evolve into osteoarthritic change in some cases.Focal cartilage defects have been detected in up to 63% of patients undergoing arthroscopy of the knee and fortunately most of them remain symptomless for a long time.
However, symptomatic lesions can result in significant pain and morbidity and a prospective clinical study has demonstrated that the risk of patients with a cartilage lesion to progress to osteoarthritis is enhanced more than fivefold. Thus, such patients require a treatment filling the gap between palliation and resurfacing via arthroplastia.
