Summary: This study demonstrates that melatonin pretreatment can restore endothelial progenitor cell (EPC) function impairment and improve circulation recovery in a diabetic critical limb ischemia mouse model. Melatonin reverses the harmful effects of hyperglycemia on EPC through AMPK-related mechanisms and increases eNOS phosphorylation and heme oxygenase-1 expression. Melatonin treatment augments EPC function and neovascularization in response to ischemia in diabetic mice.

Summary: Bone regeneration is a complex process relying on interactions between osteogenesis and angiogenesis. Tissue engineering provides strategies with regenerative cell sources, growth factors, and mechanical stimulation. Vascularization is crucial for bone formation and function, with studies showing synergy between mesenchymal stromal cells (MSCs) and endothelial progenitor cells (EPCs) in promoting regeneration.

Summary: The study found that the expression of genes in CB-MNCs and CD31-positive MNCs in severe PE patients showed significant down-regulation or up-regulation, while mild PE patients did not show significant differences. These results suggest that severe PE has distinct angiogenic and inflammatory signatures compared to the normal group and mild PE.

Summary: The study showed that G-CSF can accelerate bone regeneration and modulate the mobilization of progenitor cells during the process of distraction osteogenesis, promoting bone consolidation. In the early phase of consolidation, the G-CSF group exhibited lower osteoclast activity and a trend of increased osteoblast activity, while significantly lower neovascularization was observed in the late phase of consolidation.

Summary: Mesenchymal stromal cells (MSCs) have been shown to play a supportive role in the expansion and engraftment of hematopoietic stem and progenitor cells (HSPCs). In this study, we developed a co-culture system using bone marrow (BM)-MSCs to improve the transplantation outcome of CRISPR-Cas9 gene-edited (GE) human HSPCs. We found that BM-MSCs can produce hematopoietic supportive and anti-inflammatory factors that enhance the expansion and clonogenic potential of GE-HSPCs in vitro, leading to improved engraftment and early phase hematological reconstitution in transplanted mice. This study suggests a potential clinical application of BM-MSCs in promoting successful transplantation of GE-HSPCs.

Summary: By co-culturing with OP9, we can enhance the M2, tissue-protecting, and pro-angiogenic features of umbilical cord blood cells, which leads to amelioration of symptoms in mouse models of cerebral infarction.

Summary: In a rat calvarial defect model, adding endothelial cells (ECs) to a culture of bone marrow stromal cells (BMSCs) has been reported to enhance bone formation significantly. This study aimed to further investigate the ossification process of newly formed osteoid and host response to poly(L-lactide-co-1,5-dioxepan-2-one) [poly(LLA-co-DXO)] scaffolds. The results showed increased expression of endochondral ossification-related genes in the CO group, along with the formation of cartilage-like tissue in the scaffold pores and the observation of multinucleated giant cells (MNGCs) surrounding the scaffold fragments.

Summary: The human organism requires the production of approximately 1 trillion new blood cells per day through hematopoiesis in the bone marrow, regulated by the BM microenvironment and HSPCs. The BM niche, defined by interactions between HSPCs and non-hematopoietic cells, controls HSPC maintenance and orchestrates hematopoiesis according to the body's needs. Mesenchymal stromal cells (MSCs) play a key role in the BM niche by regulating HSPC homeostasis and impacting the outcome of hematopoietic stem cell transplantation.

Summary: Osteosarcoma, a bone cancer typically found in adolescents, is closely related to the conversion of bone marrow during adolescence. This study compared the differentiation potential of bone marrow cells from different regions with osteosarcoma cell lines. The results showed distinct differences in the differentiation abilities of hematopoietic and adipocyte-rich bone marrow, which correlated with specific characteristics of the osteosarcoma cell lines.

Summary: MSCs have shown exceptional safety in clinical trials, but reliable potency assays to predict their immunosuppressive efficacy are still lacking. They are approved for certain diseases in Japan and Europe, but not in the United States. Researchers discuss potential mechanisms of action, experimental models, and approaches for identifying MSC effects in vivo.
