BACKGROUND Interleukin-17A (IL-17A) is not only an important modulator of inflammatory reactions, but also affects bone metabolism, which is involved in osteogenic differentiation of stem cells. However, the role and mechanism of IL-17A in osteogenic differentiation of bone mesenchymal stem cells (BMSCs) are not fully understood. In this study, we investigated the role and mechanism of IL-17A i...
Aging has less effect on adipose-derived mesenchymal stem cells (ADSCs) than on bone marrow-derived mesenchymal stem cells (BMSCs), but whether the fact holds true in stem cells from elderly patients with osteoporotic fractures is unknown. In this study, ADSCs and BMSCs of the same donor were harvested and divided into two age groups. Group A consisted of 14 young patients (36.4 ± 11.8 years ol...
One of the big challenges in tissue engineering for treating large bone defects is to promote the angiogenesis of the tissue-engineered bone. Hypoxia inducible factor-1α (HIF-1α) plays an important role in angiogenesis-osteogenesis coupling during bone regeneration, and can activate a broad array of angiogenic factors. Dimethyloxaloylglycine (DMOG) can activate HIF-1α expression in cells at nor...
BACKGROUND Transplantation with bone marrow-derived mesenchymal stem cells (BMSCs) improves the survival of neurons and axonal outgrowth after stroke remains undetermined. Here, we investigated whether PI3K/AKT signaling pathway is involved in these therapeutic effects of BMSCs. METHODOLOGY/PRINCIPAL FINDINGS (1) BMSCs and cortical neurons were derived from Sprague-Dawley rats. The injured ne...
Bone marrow-derived mesenchymal stem cells (BMSCs) have shown great promise for ischemic tissue repair. However, poor viability of transplanted BMSCs within ischemic tissues has limited their therapeutic potential. Numerous evidences suggested that reactive oxygen species (ROS) generated and apoptosis play an important role in regulation BMSCs loss at the ischemic site. Uncoupling protein 2 (UC...
Clinical observations show that the current spinal fusion with internal fixation has a nonfusion rate of 5%-35%; however, methods to promote are limited. This study aimed investigate role SDF-1-induced directional chemotaxis BMSCs in bone marrow chimera intervertebral mouse model. were isolated from and identified by detecting CD44/CD34 positive cells. (GFP-BMSCs) labeled GFP for tracking vivo....
The aim was to investigate changes between autophagy and apoptosis in alveolar bone mesenchymal stem cells (BMSCs) under orthodontic pressure the effect on osteogenesis BMSCs. Twenty-four beagle canine teeth were used as experimental models. control group received no treatment, while groups, canines moved distally with 150 g of force for 7 days, 14 days 28 days. Bone remodeling detected by H&E ...
The current study examined the influence of culture substrates modified with the functional groups -OH, -COOH, -NH2, and -CH3 using SAMs technology, in conjunction with TAAB control, on the osteogenic differentiation of rabbit BMSCs. The CCK-8 assay revealed that BMSCs exhibited substrate-dependent cell viability. The cells plated on -NH2- and -OH-modified substrates were well spread and homoge...
Neuropathic pain remains a pressing clinical problem. Here, we demonstrate that a local, intrathecal (i.t.) injection of bone marrow stromal cells (BMSCs) following lumbar puncture alleviates early- and late-phase neuropathic pain symptoms, such as allodynia and hyperalgesia, for several weeks in murine chronic constriction injury (CCI) and spared nerve injury models. Moreover, i.t. BMSCs reduc...
Transplantation of bone marrow stromal cells (BMSCs) reduces astrogliosis, decreases scar thickness and improves neurological functional recovery after brain damage. It is believed that transplanted BMSCs have a profound influence on astrocytes. To obtain the possible mechanism in their interaction, a co-culture system between BMSCs and astrocytes were set to investigate whether BMSCs could mod...
