Hsc self-renew

WebChronic inflammation leads to HSC lose self-renewal. A study conducted in the mouse model clearly shows that repeated exposures to inflammatory stimuli such as LPS, negatively affected HSC function. 5 Furthermore, inflammation drives myeloid fate decisions in HSCs and reduces lymphopoiesis. 4,6,15 WebThe tumor suppressor p53, in addition to its role in the regulation of the cell cycle, plays an importatn role in HSC self-renewal, although it has not fully resolved. Here we report that in super-p53 mice (sp53), which carry one extra gene dose of p53, the miR-33 is down-regulated in HSCs and highly expressed in MPPs.
