Fivefold increase in derivation rates of mouse embryonic stem cells after supplementation of the media with multiple factors
The objective of this study was to determine the ability of multiple-factor supplementation to augment derivation of mouse embryonic stem (mES) cells. Three factors, leukemia inhibitory factor (LIF), Parke-Davis 98059 (PD98059), and 6-bromoindirubin-3′-oxime (BIO), were added as supplements (individ...
