Objectives: Recent findings suggest that in response to repair-to-injury bone marrow mesenchymal stem cells (BMSCs) participate in the process of angiogenesis. It is unclear what role BMSCs play in the structure of the vessel wall. In present study, we aimed to determine whether BMSCs had the capacity of endothelial cells (ECs).
Methods: BMSCs were separated and cultured. FACS and RT-PCR analysis confirmed the gene expression phenotype. The capacity of migration and adhesion and the ultrastructure of BMSCs were examined. The effect of BMSCs transplantation on the vascular repair was investigated in a murine carotid artery-injured model.
Results: BMSCs could express some markers and form the tube-like structure. The migration and adhesion capacity of BMSCs increased significantly after stimulated. In addition, BMSCs had the intact cell junction. In vivo the local transfer of BMSCs differentiated into neo-endothelial cells in the injury model for carotid artery and contributed to the vascular remodeling.
Conclusion: These results showed that BMSCs could contribute to neointimal formation for vascular lesion and might be associated with the differentiation into ECs, which indicated the important therapeutic implications for vascular diseases.

Postmenopausal osteoporosis (PMOP) is a chronic systemic bone metabolism disorder. Promotion in the patterns of human bone marrow mesenchymal stem cells (hBMSCs) differentiation towards osteoblasts contributes to alleviating osteoporosis. Aucubin, a natural compound isolated from the well-known herbal medicine Eucommia, was previously shown to possess various pharmacological effects.

Facilitating neuronal differentiation of stem cells and microenvironment remodeling are the key challenges in cell-based transplantation strategies for central nervous system regeneration. Herein, the study harnesses the intrinsic pro-neural differentiation potential of nerve-derived extracellular matrix (NDEM) and its specific affinity for cytokines to develop an NDEM-gelatin methacryloyl(gelMA)-based bifunctional hydrogel delivery system for stem cells and cytokines. This system promotes the neural differentiation of bone marrow stromal cells (BMSCs) and optimizes the therapeutic index of Interleukin-4 (IL-4) for spinal cord injury (SCI) treatment.

Background: Steroid-induced osteonecrosis of the femoral head (SONFH) is a pathological condition primarily driven by an impaired balance in the differentiation of bone marrow mesenchymal stem cells (BMSCs) into adipogenic and osteogenic lineages. This study aimed to explore the role of miR-129-5p as a regulator of SONFH progression and associated mechanisms.
Methods: BMSCs were harvested from a rat SONFH model.

The involvement of neurons in the peripheral nervous system is crucial for bone regeneration. Mimicking extracellular matrix cues provides a more direct and effective strategy to regulate neuronal activity and enhance bone regeneration. However, the simultaneous coupling of the intrinsic mechanical-electrical microenvironment of implants to regulate innervated bone regeneration has been largely neglected.

In this editorial, we will discuss the article by Tang published in the recent issue of the . They explored an innovative approach to enhancing gemcitabine (GEM) delivery and efficacy using human bone marrow mesenchymal stem cells (HU-BMSCs)-derived exosomes. The manufacture of GEM-loaded HU-BMSCs-derived exosomes (Exo-GEM) has been optimized.
