New hope in regenerative medicine
Harvard Stem Cell Institute researchers at Boston Children’s Hospital have reprogrammed mature blood cells from mice into blood-forming hematopoietic stem cells (HSCs), using a cocktail of eight genetic switches called transcription factors. The reprogrammed cells have the functional hallmarks of HSCs and are able to self-renew like those cells.
