Abstract ObjectivesSteroid-induced osteoporosis (SIOP) is a secondary osteoporosis, which is a systemic bone disease characterized by low bone mass, bone microstructure damage, increased bone fragility, and easy fracture. However, the specific mechanism remains unclear. Glucocorticoid-induced death of osteoblasts and bone marrow mesenchymal stem cells (BMSCs) is an important factor in SIOP. Ferroptosis is an iron-dependent programmed cell death that differs from apoptosis, cell necrosis, and autophagy, which can be induced by many factors. Herein, we aimed to explore whether glucocorticoids (GCs) cause ferroptosis in BMSCs and determine possible treatment pathways and mechanisms of action. Melatonin (MT), a hormone secreted by the pineal gland, displays strong antioxidant abilities to scavenge free radicals and alleviates ferroptosis in many tissues and organs. MethodsIn this study, we used high-dose dexamethasone (DEX) to observe whether glucocorticoids induced ferroptosis in BMSCs. We then assessed whether MT can inhibit the ferroptotic pathway, thereby providing early protection against GC-induced SIOP, and investigated the signaling pathways involved.ResultsIn vitro experiments showed that MT intervention significantly improved GC-induced ferroptosis in BMSCs and significantly improved SIOP in vivo. Pathway analysis showed that MT improves ferroptosis by activating the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) axis. MT upregulates expression of PI3K, which is an important regulator of ferroptosis resistance. PI3K activators mimic the anti-ferroptosis effect of MT, but after blocking the PI3K pathway, the effect of MT is weakened. Obviously, MT can protect against SIOP induced by GC. Notably, even after GC-induced ferroptosis begins, MT can confer protection against SIOP. ConclusionOur research confirms that GC-induced ferroptosis is closely related to SIOP. Melatonin can inhibit ferroptosis by activating the PI3K-AKT-mTOR signaling pathway, thereby reducing the occurrence of steroid-induced osteoporosis. Therefore, MT may provide a novel strategy for preventing and treating SIOP.

The effectiveness of mesenchymal stem cells (MSC) in the treatment of cartilage diseases has been demonstrated to be attributed to the paracrine mechanisms, especially the mediation of exosomes. But the exosomes derived from unsynchronized MSCs may be nonhomogeneous and the therapeutic effect varies between samples. Aim: To produce homogeneous and more effective exosomes for the regeneration of cartilage. Materials & methods: In this study we produced specific exosomes from bone marrow MSCs (BMSC) through kartogenin (KGN) preconditioning and investigated their performance in either in vitro or in vivo experiments. Results & conclusion: The exosomes derived from KGN-preconditioned BMSCs (KGN-BMSC-Exos) performed more effectively than the exosomes derived from BMSCs (BMSC-Exos). KGN preconditioning endowed BMSC-Exos with stronger chondral matrix formation and less degradation.

Biocompatible scaffolding materials play an important role in bone tissue engineering. This study sought to develop and characterize a nano-hydroxyapatite (nHA)/collagen I (ColI)/multi-walled carbon nanotube (MWCNT) composite scaffold loaded with recombinant bone morphogenetic protein-9 (BMP-9) for bone tissue engineering by in vitro and in vivo experiments. The composite nHA/ColI/MWCNT scaffolds were fabricated at various concentrations of MWCNTs (0.5, 1, and 1.5% wt) by blending and freeze drying. The porosity, swelling rate, water absorption rate, mechanical properties, and biocompatibility of scaffolds were measured. After loading with BMP-9, bone marrow mesenchymal stem cells (BMMSCs) were seeded to evaluate their characteristics in vitro and in a critical sized defect in Sprague-Dawley rats in vivo. It was shown that the 1% MWCNT group was the most suitable for bone tissue engineering. Our results demonstrated that scaffolds loaded with BMP-9 promoted differentiation of BMMSCs into osteoblasts in vitro and induced more bone formation in vivo. To conclude, nHA/ColI/MWCNT scaffolds loaded with BMP-9 possess high biocompatibility and osteogenesis and are a good candidate for use in bone tissue engineering.

Abstract Background: Due to its low capacity for self-repair, articular cartilage is highly susceptible to damage and deterioration, which leads to the development of degenerative joint diseases such as osteoarthritis. Menstrual blood-derived mesenchymal stem cells (MenSCs) are much less characterized compared to bone marrow mesenchymal stem cells (BMMSCs). However, MenSCs seem an attractive alternative to classical BMMSCs due to ease of access and broader differentiation capacity. The aim of this study was to evaluate chondrogenic differentiation potential of MenSCs and BMMSCs stimulated with transforming growth factor β (TGF-β3) and activin A, member of the TGF-β superfamily of proteins.Methods: MenSCs (n=6) and BMMSCs (n=5) were isolated from different healthy donors. Expression of cell surface markers CD90, CD73, CD105, CD44, CD45, CD14, CD36, CD55, CD54, CD63, CD106, CD34, CD10, Notch1 was analysed by flow cytometry. Cell proliferation capacity was determined using CCK-8 proliferation kit. Adipogenic differentiation capacity was evaluated according to Oil-Red staining, osteogenic differentiation - Alizarin Red staining. Chondrogenic differentiation (Activin A and TGF-β3 stimulation) was induced in vitro and in vivo (subcutaneous scaffolds in nude BALB/c mice) and investigated by histologically and by expression of chondrogenic genes (collagen type II, aggrecan). Activin A protein production was evaluated by ELISA.Results: MenSCs exhibited a higher proliferation rate, as compared to BMMSCs, and a different expression profile of several cell surface markers. Activin A stimulated collagen type II gene expression and glycosaminoglycan synthesis in TGF-β3 treated MenSCs but not in BMMSCs, both in vitro and in vivo, although the effects of TGF-β3 alone were more pronounced in BMMSCs in vitro. Conclusion: These data suggest that activin A exerts differential effects on the induction of chondrogenic differentiation in MenSCs vs. BMMSCs, which implies that different mechanisms of chondrogenic regulation are activated in these cells. Following further optimisation of differentiation protocols and the choice of growth factors, potentially including activin A, MenSCs may turn out to be a promising population of stem cells for the development of cell-based therapies with the capacity to stimulate cartilage repair and regeneration.Trial registration: Not applicable.

Marrow Mesenchymal Stem Cells

Somatic cell nuclear transfer efficiency is based on the capacity of the donor cell to be reset and reprogrammed to an embryonic state. So, the less differentiated the donor cells are, the more easily they could be reprogrammed by a recipient cytoplasm. Failures on appropriate nuclear reprogramming frequently lead to abnormalities associated with the placenta, umbilical cord, birthweight, and limbs. In the present study, we evaluated the efficiency of bone marrow mesenchymal stem cells (BM-MSC) compared with adult fibroblasts (AF) as nuclear donors in horse cloning and evaluated both in vitro and in vivo development of the embryos generated. Moreover, we focused on comparing the health of the foals generated and on the presence of anatomical abnormalities in foals produced from the different treatments. Embryos produced by AI, recovered by uterine flushing, and transferred to recipient mares were used as controls. All variables were analysed by Fisher test (P < 0.05). The cloning procedure was performed according to Olivera et al. (2016 PLoS One 11, e0164049, 10.1371/journal.pone.0164049). Both cleavage and blastocyst rates were higher when MSC were used as nuclear donors (P < 0.05). Cleavage rates were 85.6% (3875/4527) v. 90.2% (3095/3432) and blastocyst rates were 10.9% (492/4527) and 18.1% (622/3432) for AF and MSC groups, respectively. In the AF group, 476 blastocysts were transferred to recipient mares (232 transfers), and in the MSC group, 594 blastocysts were transferred 297 transfers). In the AI control group, 88 embryos were transferred. Pregnancies were diagnosed by transrectal ultrasonography 15 days after embryo transfer in all the groups. Pregnancy rates were similar between both cloning groups (41/232, 17.7% and 37/297, 12.5%for AF and MSC, respectively), but higher in the AI group (71/88, 80.7%). However, significant differences were observed in the birth of viable offsprings among the cloning groups. Despite similar rates of foal delivery (AF, 17/41, 41.5%; MSC, 21/37, 56.7%), a higher proportion of viable foals were obtained from the MSC group (20/37, 54.1%) compared with the AF group (9/41, 22%; P < 0.05). Surprisingly, as in the AI group (63/63, 100%), all of the viable foals obtained using MSC (20/20, 100%) were considered normal and did not show abnormalities associated with cloning. In contrast, in the AF group, only 4/9 (44.4%) were considered normal foals. The defects present in the other 5 foals were related to flexural and angular limb deformities and umbilical cord malformations. These were corrected rapidly with standard treatments or, in the case of the umbilical cords, minor surgery. This study shows for the first time that BM-MSC can be used as nuclear donors in horse cloning and that the foals obtained are as healthy as those produced by AI, showing no abnormalities related to deficiencies in nuclear reprogramming.
