Mesenchymal Stem Cell Differentiation

Bone morphogenetic proteins (BMPs) play vital roles in regulating stem cell maintenance and differentiation. BMPs can induce osteogenesis and inhibit myogenesis of mesenchymal stem cells. Canonical BMP signaling is stringently controlled through reversible phosphorylation and nucleocytoplasmic shuttling of Smad1, Smad5, and Smad8 (Smad1/5/8). However, how the nuclear export of Smad1/5/8 is regulated remains unclear. Here we report that the Ran-binding protein RanBP3L acts as a nuclear export factor for Smad1/5/8. RanBP3L directly recognizes dephosphorylated Smad1/5/8 and mediates their nuclear export in a Ran-dependent manner. Increased expression of RanBP3L blocks BMP-induced osteogenesis of mouse bone marrow-derived mesenchymal stem cells and promotes myogenic induction of C2C12 mouse myoblasts, whereas depletion of RanBP3L expression enhances BMP-dependent stem cell differentiation activity and transcriptional responses. In conclusion, our results demonstrate that RanBP3L, as a nuclear exporter for BMP-specific Smads, plays a critical role in terminating BMP signaling and regulating mesenchymal stem cell differentiation.

Skeletogenesis, either during development, post-injury or for maintenance, is a carefully coordinated process reliant on the appropriate differentiation of mesenchymal stem cells. Some well described, as well as a new regulator of this process (adenosine receptors), are alike in that they signal via cyclic-AMP (cAMP). This review highlights the known contribution of cAMP signalling to mesenchymal stem cell differentiation to osteoblasts and to chondrocytes. Focus has been given to how these regulators influence the commitment of the osteochondroprogenitor to these separate lineages.

Abstract BackgroundCells produce extracellular vesicles, such as exosomes and microvesicles, which are used for intracellular communication. Cell-free therapies could be enhanced by using mesenchymal stem cell-derived exosomes. Preconditioning parental cells affects the properties of their exosomes. This study aimed to investigate the role of L-ascorbic acid (LAA) and CoCl2 in the exosomes produced by human Wharton’s jelly mesenchymal stem cells (hWJ MSC) and its potential to induce chondrogenic differentiation of stem cells was also studied.. MethodThe cells were obtained from umbilical cords and characterized based on mesenchymal stem cell criteria. The cells were cultured in a serum-free medium containing LAA and CoCl2. Exosomes produced by the cells were isolated and their morphology observed with Transmission Electron Microscopy. The presence of CD 63 was confirmed using ELISA. The particle size distribution and exosome concentration were analyzed with Nanoparticle Tracking Analysis (NTA). The ability of exosomes to induce stem cell differentiation into chondrocytes was investigated using the Alcian blue assay and immunocytochemistry.ResultsStem cells were successfully isolated from the human umbilical cord. The cells can differentiate into adipocytes, chondrocytes, and osteocytes. Flowcytometry analysis showed the specific surface marker of mesenchymal stem cells. Exosomes isolated from pretreatment cells showed round-shaped morphology and confirmed the presence of CD 63. NTA analysis revealed that pretreatment of cells with LAA increases exosome yields. LAA supplementation in cell medium under hypoxic conditions induced by CoCl2 produces exosomes that can induce the chondrogeic differentiation of stem cells, confirmed by the presence of glycosaminoglycan and collagen type 2.ConclusionExosomes produced by preconditioning hWJ-MSC with LAA in hypoxic conditions have the potential to enhance human Wharton Jelly stem cell differentiation into chondrocytes.

Fluorescent nanodiamond (FND) indicated that it has excellent biocompatibility and photostability,so it well suited for long-term labeling and tracking of stem cells. There are many reports concerning the factors controlling stem cell differentiation. However, still little knowledge about the biomaterials properties influence stem cell alive, growth and differentiation processing. In this study, we evaluate the effect of fluorescent nanodiamond in in vitro culture and differentiation of ucMSC into hepatocyte-like cell. Mesenchymal stem cells (MSCs) were isolated from the umbilical cord (UC) and CD markers were analyzed by flow cytometry and genes expression. For hepatic differentiation of UC-MSCs, cells were induced with HGF and DMSO treated. FND was supply in the experimental group which 10 g/ml in 4 hours. The FND uptake was detected of fluorescence intensity of FND in cells by flow cytometry and laser scan microscopy. The effect of FND into UCMSCs was not only evaluated by the cell alive and growth assay but also effective differentiation throughout morphology charging or gene expression levels of AFP, ALB, and HNF4 were determined by RT-PCR and real-time PCR. The result showed that the FND was well uptake in UCMSCs. It was no affected into ability of the cell alive and growth. The existence of FNDs does not disturb the functions of UC-MSCs differentiation into hepatocyte-like cell. FND can be utilized for the labeling and tracking of UC-MSCs and hepatocyte-like cell in homing research.

Abstract Background. Bone reconstruction in congenital craniofacial differences, which affect about 2-3% of newborns, has long been the focus of intensive research in the field of bone tissue engineering. The possibility of using mesenchymal stem cells in regenerative medicine protocols has opened a new field of investigation aimed at finding optimal sources of multipotent stem cells that can be isolated via non-invasive procedures. Here we analysed whether levator veli palatini muscle fragments, which can be readily obtained in non-invasive manner during surgical rehabilitation of cleft p­­atients during palatoplasty, represent a novel source of MSCs with osteogenic potential. Methods. We obtained levator veli palatini muscle fragments, in non-invasive procedure during surgical rehabilitation of 5 unrelated cleft palate patients (palatoplasty surgery). The levator veli palatini muscle fragments was used to obtain the mesenchymal cells using pre-plating technique in a clean rooms infrastructure and all procedures were performed at good practices of manipulation conditions. To prove that levator veli palatini muscle are mesenchymal stem cells they were induced to flow cytometry analysis and to differentiation into bone, cartilage, fat and muscle. To demonstrate the osteogenic potential of these cells in vivo a bilateral full thickness calvarial defect model was made in immunocompentent rats.Results. Flow cytometry analysis showed that the cells were positive for mesenchymal stem cell antigens (CD29, CD73, CD90), while negative for hematopoietic (CD45) or endothelial cell markers (CD31). Moreover, these cells were capable of undergoing chondrogenic, adipogenic, osteogenic and skeletal muscle cell differentiation under appropriate cell culture conditions characterizing them as mesenchymal stem cell. Defects treated with CellCeramTM scaffolds seeded with levator veli palatini muscle cells showed significantly greater bone healing compared to defects treated with acellular scaffolds. Conclusion. We have demonstrated that cells derived from levator veli palatini muscle have phenotypic characteristics similar to other mesenchymal stem cells, both in vitro and in vivo. Our findings suggest that these cells may have clinical relevance in the rehabilitation of patients with cleft palate and other craniofacial anomalies characterized by significant bone deficit.
