Abstract: Abstract: Epigenetics plays important roles in differentiation and maturation of stem cells. By adjusting dynamically the methylation status of histone, histone lysine specific demethlase 1 (LSD1) regulates activation and inhibition of gene transcription, as well as inactivation of X chromosome. Researches demonstrate that LSD1 expresses in cancer stem cells, neural stem cells and induced pluripotent stem cells, and also affects the proliferation and differentiation of these stem cell. Here, we will review the recent advances of LSD1’s regulatory roles in these stem cells.
Key words: LSD1 ; stem cells; proliferation; differentiation; regulation
