Mesenchymal stem cells are multipotent adult stem cells that are present in multiple tissues, including umbilical cord, bone marrow and fat tissue. Mesenchymal stem cells can self-renew by dividing and can differentiate into multiple tissues including bone, cartilage, muscle and fat cells, and connective tissue.
In mitochondria transplantation, the limited activity and yield of mitochondria constrain their clinical application for mitochondrial diseases. Here, authors develop a method for producing mitochondria-enriched extracellular vesicles, which offer high-quality, abundant mitochondrial material for transplantation.
Ewing sarcoma (ES) is characterized by EWSR1/ETS gene rearrangements with unknown cellular origin. Here, authors show that expressing the EWS::FLI1 oncogene in human embryonic mesenchymal stem cells induces an Ewing sarcoma-like transcriptome and forms tumors in mice.
Adipogenesis of adipose progenitor cells is considered metabolically beneficial. Two laboratories have simultaneously discovered that adipose progenitors also give rise to structural WNT-regulated adipose tissue-resident (SWAT) cells during adipogenesis to maintain the progenitor pool.
New research shows that combining a hydrogel with nanozymes to modify the hypoxic, inflammatory joint environment in rheumatoid arthritis enables stem cells to promote osseointegration.
Coating mesenchymal stromal cells with a soft gel incorporating specific chemomechanical cues that enhance the production of collagenases enhances the ability of the cells to inhibit aberrant tissue remodelling in mice with fibrotic lungs.
