... The specific protein described for the neural stem cell niche is β -catenin. It is located in the cytoplasmic region of E-cadherin, an epithelial trans-membrane protein, and is therefore considered to be an intrinsic factor. β –catenin serves two primary unrelated roles; contributing to cell-cell ad ...
