AbstractMesenchymal stem cells (MSCs) are pluripotent stem cells derived from mesoderm during early development that are characterized by high self-renewal ability and multidirectional differentiation potential. These cells are present various tissues in the human body and can be cultured in vitro. Under specific conditions, MSCs can differentiate into osteoblasts, neuron-like cells, adipocytes and muscle cells and so on, therefore, have a great application value in cell replacement therapy and tissue repair. In recent years, the application of MSCs in rheumatic diseases has received increasing attention. On the one hand, MSCs have the ability to differentiate into bone and cartilage cells; on the other hand, these stem cells are also involved in immune regulation, resulting in the alleviation of inflammation and anti-fibrotic properties and the promotion of vascular repair, thus bringing new hope for the treatment of rheumatic diseases. This article reviews the clinical progress in MSC application for the treatment of rheumatic diseases.

Induced Pluripotent

Primary Ovarian Insufficiency (POI) is one of the main diseases causing female infertility that occurs in about 1% of women between 30-40 years of age. There are few effective methods for the treatment of women with POI. In the past few years, stem cell-based therapy as one of the most highly investigated new therapies has emerged as a promising strategy for the treatment of POI. Human pluripotent stem cells (hPSCs) can self-renew indefinitely and differentiate into any type of cell. Human Embryonic Stem Cells (hESCs) as a type of pluripotent stem cells are the most powerful candidate for the treatment of POI. Human-induced Pluripotent Stem Cells (hiPSCs) are derived from adult somatic cells by the treatment with exogenous defined factors to create an embryonic-like pluripotent state. Both hiPSCs and hESCs can proliferate and give rise to ectodermal, mesodermal, endodermal, and germ cell lineages. After ovarian stimulation, the number of available oocytes is limited and the yield of total oocytes with high quality is low. Therefore, a robust and reproducible in-vitro culture system that supports the differentiation of human oocytes from PSCs is necessary. Very few studies have focused on the derivation of oocyte-like cells from hiPSCs and the details of hPSCs differentiation into oocytes have not been fully investigated. Therefore, in this review, we focus on the differentiation potential of hPSCs into human oocyte-like cells.

The Impact

ABSTRACTHuman mesenchymal stem cells (hMSCs) were routinely cultured on tissue-culture polystyrene (TCPS) to investigate the in vitro aging and cell stiffening. hMSCs were also cultured on thermoplastic polyurethane (TPU), which is a biocompatible polymer with an elastic modulus of approximately 12.9MPa, to investigate the impact of substrate elastic modulus on cell stiffening and differentiation potential. Cells were passaged over several generations on each material. At each passage, cells were subjected to osteogenic and myogenic differentiation. Local cell elastic modulus was measured at every passage using atomic force microscopy (AFM) indentation. Gene and protein expression was examined using qRT-PCR and immunofluorescent staining, respectively, for osteogenic and myogenic markers. Results show that the success of myogenic differentiation is highly reliant on the elastic modulus of the undifferentiated cells. The success of osteogenic differentiations is most likely somewhat dependent on the cell elastic modulus, as differentiations were more successful in earlier passages, when cells were softer.

AbstractHuman mesenchymal stem cells (hMSCs), when cultured on tissue culture plate (TCP) for in vitro expansion, they spontaneously lose their proliferative capacity and multi-lineage differentiation potential. They also lose their distinct spindle morphology and become large and flat. After a certain number of population doubling, they enter into permanent cell cycle arrest, called senescence. This is a major roadblock for clinical use of hMSCs which demands large number of cells. A cell culture system is needed which can maintain the stemness of hMSCs over long term passages yet simple to use. In this study, we explore the role of substrate rigidity in maintaining stemness. hMSCs were serially passaged on TCP and 5 kPa poly-acrylamide gel for 20 population doubling. It was found that while on TCP, cell growth reached a plateau at cumulative population doubling (CPD) = 12.5, on 5 kPa gel, they continue to proliferate linearly till we monitored (CPD = 20). We also found that while on TCP, late passage MSCs lost their adipogenic potential, the same was maintained on soft gel. Cell surface markers related to MSCs were also unaltered. We demonstrated that this maintenance of stemness was correlated with delay in onset of senescence, which was confirmed by β-gal assay and by differential expression of vimentin, Lamin A and Lamin B. As preparation of poly-acrylamide gel is a simple, well established, and well standardized protocol, we believe that this system of cell expansion will be useful in therapeutic and research applications of hMSCs.One Sentence SummaryhMSCs retain their stemness when expanded in vitro on soft polyacrylamide gel coated with collagen by delaying senescence.Significance StatementFor clinical applications, mesenchymal stem cells (MSCs) are required in large numbers. As MSCs are available only in scarcity in vivo, to fulfill the need, extensive in vitro expansion is unavoidable. However, on expansion, they lose their replicative and multi-lineage differentiation potential and become senescent. A culture system that can maintain MSC stemness on long-term expansion, without compromising the stemness, is need of the hour. In this paper, we identified polyacrylamide (PAA) hydrogel of optimum stiffness that can be used to maintain stemness of MSCs during in vitro long term culture. Large quantity of MSCs thus grown can be used in regenerative medicine, cell therapy, and in treatment of inflammatory diseases.

Background: Several studies have shown the relationship between poorer clinical outcomes of arthroscopic femoroacetabular impingement syndrome surgery and focal chondral defects or global chondromalacia/osteoarthritis. Although recent studies described good outcomes after the conjunctive application of synovial mesenchymal stem cells (MSCs), none demonstrated the application of synovial MSCs for cartilaginous hip injuries. Purpose: To compare the characteristics of MSCs derived from the paralabral synovium and the cotyloid fossa synovium and determine which is the better source. Study Design: Controlled laboratory study. Methods: Synovium was harvested from 2 locations of the hip—paralabral and cotyloid fossa—from 18 donors. The number of cells, colony-forming units, viability, and differentiation capacities of adipose, bone, and cartilage were collected and compared between groups. In addition, real-time polymerase chain reaction was used to assess the differentiation capacity of adipose, bone, and cartilage tissue from both samples. Results: The number of colonies and yield obtained at passage 0 of synovium from the cotyloid fossa was significantly higher than that of the paralabral synovium ( P < .01). In adipogenesis experiments, the frequency of detecting oil red O–positive colonies was significantly higher in the cotyloid fossa than in the paralabral synovium ( P < .05). In osteogenesis experiments, the frequency of von Kossa and alkaline phosphatase positive colonies was higher in the cotyloid fossa synovium than in the paralabral synovium ( P < .05). In chondrogenic experiments, the chondrogenic pellet culture and the gene expressions of COL2a1 and SOX9 were higher in the cotyloid fossa synovium than in the paralabral synovium ( P < .05). Conclusion: MSCs from the cotyloid fossa synovium have higher proliferation and differentiation potential than do those from the paralabral synovium and are therefore a better source. Clinical Relevance: Synovial cells from the cotyloid fossa synovium of patients with femoroacetabular impingement syndrome are more robust in vitro, suggesting that MSCs from this source may be strongly considered for stem cell therapy.

Differentiation Potential

Mesenchymal stem cells (MSC) are isolated from bone marrow or other tissues, and have properties of self renewal and multilineage differentiation ability. The current study investigated the in vitro differentiation potential of porcine bone marrow derived MSCs into hepatocyte-like cells. The MSC were isolated from the bone marrow of adult miniature pigs (7 months old, T-type, PWG Micro-pig®, PWG Genetics, Seoul, Korea) and adherent cells with fibroblast-like morphology were cultured on plastic. Isolated MSCs were positive for CD29, CD44, CD73, CD90, and vimentin, and negative for CD34, CD45, major histocompatibility complex-class II (MHC-class II), and swine leukocyte antigen-DR (SLA-DR) by flow cytometry analysis. Further, trilineage differentiation of MSC into osteocytes (alkaline phosphatase, von Kossa and Alizarin red), adipocytes (Oil Red O), and chondrocytes (Alcian blue) was confirmed. Differentiation of MSC into hepatocyte-like cells was induced with sequential supplementation of growth factors, cytokines, and hormones for 21 days as described previously (Taléns-Visconti et al. 2006 World J. Gastroenterol. 12, 5834–5845). Morphological analysis, expression of liver-specific markers, and functional assays were performed to evaluate the hepatic differentiation of MSC. Under hepatogenic conditions, MSC acquired cuboidal morphology with cytoplasmic granules. These hepatocyte-like cells expressed α-fetoprotein (AFP), albumin (ALB), cytokeratin 18 (CK18), cytochrome P450 7A1 (CYP7A1), and hepatocyte nuclear factor 1 (HNF-1) markers by immunofluorescence assay. In addition, the expression of selected markers was demonstrated by Western blotting analysis. In accordance with these features, RT-PCR revealed transcripts of AFP, ALB, CK18, CYP7A1, and HNF-1α. Further, the relative expression levels of these transcripts were analysed by quantitative RT-PCR after normalizing to the expression of the endogenous control, glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Data were analysed statistically by one-way ANOVA using PASW statistics 18 (SPSS Inc., Chicago, IL, USA), and significance was considered at P < 0.05. The results showed that the relative expressions of selected marker genes in hepatocyte-like cells were significantly increased compared with that in untreated MSC. The generated hepatocyte-like cells showed glycogen storage as analysed by periodic acid-Schiff (PAS) staining. Moreover, the induced cells produced urea at Day 21 of culture compared with control MSC. In conclusion, our results indicate the potential of porcine MSC to differentiate in vitro into hepatocyte-like cells. Further studies on the functional properties of hepatocyte-like cells are needed to use porcine MSC as an ideal source for liver cell therapy and preclinical drug evaluation.

Spinal Cord Injured

In the recent era of veterinary research, stem cells have gained special attention due to their efficiency and use in clinical applications. Mesenchymal stem cells (MSC) have been extensively studied over decades, and their prospect for clinical application is recognised in human medicine. Despite numerous reports in veterinary clinical trials of stem cells, few studies have been presented regarding the in vitro characterisation of canine mesenchymal stem cells (cMSC). Therefore, their efficacy as therapeutic agents in vitro has not been much elucidated. Canine adipose-derived mesenchymal stem cells (cAMSC) were characterised as per International Society for Cellular Therapy guidelines. Culturing cells showed spindle-like morphology and high proliferation rate. They displayed positive expression of mesenchymal markers CD44, CD90, and CD105, and lacked expression of CD34 and CD45. They were also positive for expression of pluripotency-related transcription factors (Oct3/4, Nanog, and Sox2) and showed differentiation potential towards mesodermal lineages. The cAMSC were further analysed for the neuronal trans-differentiation potential. Under appropriate differentiation conditions, cAMSC displayed distinctive dendritic morphology along with axon projections. Neuronal specific genes including Nestin, β-tubulin, neurofilament protein (NF-M, NF-H), and nerve growth factor (NGF) were also positively expressed. Nevertheless, functional analysis of neuronal differentiated cAMSC displayed voltage dependence and kinetics for transient K+ and Na+ currents (Ito). Both K+ and Na+ currents were recorded in differentiated MSC by voltage steps (between −120 and +60 mV for K+ currents, −40 and +50 mV for Na+ currents), whereas control undifferentiated MSC lacked the currents. Taken together, we concluded that the cAMSC have potential to differentiate into neuron-like cells. Based on these findings, we transplanted cAMSC into the spinal cord injured dogs to evaluate their clinical efficiency under approved medical guidelines set by Gyeongsang National University Animal Medical Center (Korea). Neurological examination showed that the injured dog had undergone hind limb paralysis and lost deep pain sensation due to an L2 spinal cord lesion, as detected by CT and MRI. The dog was diagnosed with traumatic L2 intradural spinal cord contusion, and decompression surgery was performed, but deep pain sensation did not recover. Therefore, each cAMSC (diluted in 0.5 mL of saline) was transplanted into spinal cord segment (L2~L3) 5 times at 1-week intervals. The dog showed mild recovery of deep pain sensation by neurological examinations and exhibited gradual improvement in hind limb function. Finally, we concluded that transplantation of cAMSC has a beneficial therapeutic effect on spinal cord injury. This study also provides a significant advantage in understanding the potential of MSC-based products in veterinary clinical applications.

The discovery of the multipotent lineage of mesenchymal stem cells has dawned a new age in tissue engineering, where an autologous cell-seeded scaffold can be implanted into different therapeutic sites. Mesenchymal stem cells have been reported to differentiate into numerous anchorage-dependent cell phenotypes, including neurons, adipocytes, myoblasts, chondrocytes, tenocytes, and osteoblasts. A seminal work detailing that mesenchymal stem cells can be directed towards differentiation of different cell types by substrate stiffness alone [1] has led to numerous studies attempting to understand how cells can sense the stiffness of their substrate [2–3] Substrate stiffness has been shown to be an inducer of stem cell differentiation. MSCs on extremely soft substrates (250 Pa), similar to the stiffness of bone marrow, became quiescent but still retained their multipotency [4]. Elastic substrates in the stiffness range of 34 kPa revealed MSCs with osteoblast morphology, and osteocalcin along with other osteoblast markers were expressed [1]. However, osteogenesis has been found to increase on much stiffer (20–80 kPa) [5–6] (400 kPa) [7] as well as much softer substrates (75 Pa) [8]. Overall, cells have increased projected cell area and proliferation on stiffer substrates, leading to higher stress fiber formation. This study seeks to understand if the stiffness of the substrate has any effect on the differentiation potential of osteochondral progenitor cells into bone cells, using an in vitro dual fluorescent mouse model.

ABSTRACTCell replacement therapy holds a promising future in the treatment of degenerative diseases related to neuronal, cardiac and bone tissues. In such kind of diseases, there is a progressive loss of specific types of cells. Currently the most upcoming and trusted cell candidate is Mesenchymal Stem Cells (MSCs) as these cells are easy to isolate from the tissue, easy to maintain and expand and no ethical concerns are linked. MSCs can be obtained from a number of sources like bone marrow, umbilical cord blood, umbilical cord, dental pulp, adipose tissues, etc. MSCs help in tissue repair and regeneration by various mechanisms of action like cell differentiation, immunomodulation, paracrine effect, etc. The future of regenerative medicine lies in tissue engineering and exploiting various properties to yield maximum output. In the current review article, we have targeted the repair and regeneration mechanisms of MSCs in neurodegenerative diseases, cardiac diseases and those related to bones. Yet there is a lot to understand, discover and then understand again about the molecular mechanisms of MSCs and then applying this knowledge in developing the therapy to get maximum repair and regeneration of concerned tissue and in turn the recovery of the patient.

The integration of stem cell technology and cell sheet engineering improved the potential use of cell sheet products in regenerative medicine. This review will discuss the use of mesenchymal stem cells (MSCs) in cell sheet-based tissue engineering. Besides their adhesiveness to plastic surfaces and their extensive differentiation potential in vitro, MSCs are easily accessible, expandable in vitro with acceptable genomic stability, and few ethical issues. With all these advantages, they are extremely well suited for cell sheet-based tissue engineering. This review will focus on the use of MSC sheets in osteogenic tissue engineering. Potential application techniques with or without scaffolds and/or grafts will be discussed. Finally, the importance of osteogenic induction of these MSC sheets in orthopaedic applications will be demonstrated.
