Method for expanding stemness and differentiation potential of pluripotent cells

Method for expanding stemness and differentiation potential of pluripotent cells. The invention is based on the finding that increasing micro RNA-203 levels in induced pluripotent stem (iPSCs) or embryonic stem (ESCs) cells improves the quality cell fate potential and ability of these cells to differentiate into multiple cell lineages and to reach further maturation properties without interfering with their self-renewal properties. This effect is mediated through the mi R-203-dependent control of de novo DNA methyltransferases Dnmt3a and Dnmt3b, which in turn regulate the methylation landscape of pluripotent cells. The effect can be achieved by overexpression of micro RNA-203 or by adding micro RNA-203 or analogues thereof to the cell culture medium and can be observed using a variety of cellular and in vivo models. The generated cells are naïve pluripotent cells with an improved capacity to differentiate, that can be used to obtain more efficiently differentiated and mature cells proficient for regenerative medicine strategies.

Use of <i>Cistanche deserticola </i>polysaccharides in promoting proliferation and differentiation of female germline stem cells
