Research interests


Our group studies the role of miRNA in differentiation of hESC into neural stem cells (NSCs). We hypothesize that differentiation-associated miRNA contribute to cell cycle regulation in NSCs and help to maintain their unlimited proliferative potential. Our preliminary results show upregulation of numerous miRNAs upon differentiation of hESCs into NSCs. Interestingly, deregulation of several of these has been associated with cancer. Thus studying their expression during normal development in vitro can help to unravel potential candidates for anti-cancer therapy.
