Article Synopsis
  • Small extracellular vesicles (sEVs) from mesenchymal stromal cells (MSCs) show promise for stroke treatment by enhancing brain tissue survival and promoting angiogenesis, especially when the MSCs are cultured in hypoxic conditions.
  • In a study involving rats with permanent distal MCAO, sEVs from hypoxic MSCs improved motor-coordination recovery and reduced brain inflammation compared to untreated controls.
  • Although hypoxic MSC-sEVs did not affect infarct volume, they significantly increased proliferating endothelial cells, suggesting they have a positive impact on recovery and healing in stroke models.

Beijing Key Laboratory of Traditional Chinese Medicine Basic Research on Prevention and Treatment for Major Diseases, Experimental Research Center, China Academy of Chinese Medical Sciences, Beijing, China.

Osteoporosis is a common systemic metabolic disease characterized by a decrease in bone density and bone mass, destruction of bone tissue microstructure, and increased bone fragility leading to fracture susceptibility. Pharmacological treatment of osteoporosis is the focus of current research, and anti-osteoporosis drugs usually play a role in inhibiting bone resorption, promoting bone formation, and having a dual role. However, most of the drugs have the disadvantages of single target and high toxic and side effects.

Large skin wounds, with extensive surface area and deep vertical full-thickness involvement, can pose significant challenges in clinical settings. Traditional routes for repairing skin wounds encompass three hallmarks: 1) scab formation for hemostasis; 2) proliferation and migration of epidermal cells for wound closure; 3) proliferation, migration, and functionalization of fibroblasts and endothelial cells for dermal remodeling. However, this route face remarkable challenges to healing large wounds, usually leading to disordered structures and loss of functions in the regenerated skin, due to limited control on the transition among the three stages.
