In Cell Metabolism, researchers working at the University of Texas Southwestern Medical Center reported that when fat cells (adipocytes) are chronically stressed, as is characteristic of obesity, they can release small vesicle exosomes that are respiration-competent and essentially portions of mitochondria.

Minovia Therapeutics Ltd. will collaborate with Astellas Pharma Inc. to research, develop and commercialize cell therapy programs for treating diseases brought on by mitochondrial dysfunction. The candidates will come from Astellas’ genetically engineered, induced pluripotent stem cells. Haifa, Israel-based Minovia will receive $20 million in cash up front.

Researchers at INSERM have gained new insights into the basic biology of mesenchymal stem cell function, and how platelets improved that function in an animal model of wound healing.
