<p>'Pristine' stem cells are provided by a process of precise selection wherein stem cells exhibiting ideal behavior, good morphology and proper gene expression are selected. Stem cells are divided into pools and observed for optimum speed of growth, proper gene expression levels, and other tests indicative of healthy cell function due to lack of mutation or misrepair of genes. Autologous pools of such 'pristine' stem cells provide a source of stem cells having the genome least affected by mutation, and therefore in a more pristine state.</p> |
