網頁2013年7月18日 · Abstract. Due to its intense self-renewal kinetics and its simple repetitive architecture, the intestinal epithelium has become a prime model for studying adult stem … 網頁Using RNA interference and ectopic expression of constitutively activated forms of STAT5, we demonstrate here a function for STAT5 in the self-renewal of B cells in vitro. STAT5b isoform seemed to directly upregulate Bcl-6, and ectopic expression of Bcl-6 in B cells resulted in self-renewal and inhibition of plasma cell differentiation.
