タイトル Improving the differentiation potential of pluripotent stem cells by optimizing culture conditions.
ジャーナル Sci Rep
Abstract Embryoid cells and induced pluripotent stem cells (iPSCs) are pluripotent stem cells (PSCs). They retain differentiation and self-renewal potential. However, the differentiation potential of PSCs can be changed by the culture medium. PSCs retain their differentiation potential when cultured with medium that supports the glycolytic pathway, showing high expression of chromodomain-helicase-DNA-binding protein 7 (CHD7), but lose their differentiation potential with medium that supports mitochondrial function, showing reduced levels of CHD7. Labeling cells by their copy number variant profile revealed that genetically different PSC populations can be cultured by medium selection. Another factor that defines the self-renewal potential of PSCs is culture condition. PSCs form colonies as they grow, and spontaneous differentiation inevitably occurs along the rim of these colonies in areas that lack cell-to-cell contact; because of this, undifferentiated cell populations would diminish if differentiated cells are not removed properly. Seeding cells on a less potent cell-binding material may minimize the inclusion of differentiated cells, exploiting the reduced adhesive properties of differentiated cells. Culturing cells with medium that supports the glycolytic pathway, using CHD7 as a biomarker for differentiation potential, and culturing cells on less sticky material can improve the differentiation potential of already established PSC clones.
