This system plays a major role in the regulation of gene activity, and enables the selective expression of different functions in differentiated cell types. (sciencedaily.com)
This spectrum in gene expression is reflected in the ability of cells to undergo self - renewal or to form specific differentiated cell types. (journals.plos.org)
When the researchers implanted ES cells from a B6 mouse embryo into a B6 mouse, it formed a typical growth, called a teratoma, which is a mixture of differentiating cell types. (sciencemag.org)
