Review of «Intercellular Transfer
of Microvesicles from Young Mesenchymal Stromal Cells Rejuvenates Aged Murine Hematopoietic Stem Cells» from STEM CELLS by Stuart P. Atkinson
Now, new research from the laboratory of Vaijayanti P. Kale (National Centre for Cell Science, Pune, Maharashtra, India) has described a fascinating new approach to return lost functionality to aged mouse HSCs: the transfer
of microvesicles (MVs) containing positive regulators of autophagy derived from young mesenchymal stem cells (MSCs)[6].
