Generation of rat Induced Pluripotent Stem Cells (iPS) cells from rat embryonic fibroblasts
To generate germline-competent riPSCs, the researchers initially infected Wistar (WI) or Dark Agouti (DA) rat embryonic fibroblasts (REFs) from embryonic day 14.5 or 15.5 (E14.5 or E15.5) with a lentiviral vector carrying three mouse reprogramming factors (Oct3/4, Klf4, and Sox2) controlled by a tetracycline-responsive regulatory element and with Ubc-promoter - driven reverse tet transactivator (rtTA) and EGFP (Fig. 1A). Added doxycycline (Dox) to the culture medium on the day of infection (day 0), with rat LIF (rLIF) added to medium on day 1.
(A) Schema of inducible lentivirus vector. XbaI enzyme restriction site exists between Ubiquitin-C (Ubc) promoter and reverse tet transactivator (rtTA) element.
(B) Schematic time schedule of riPSCs generation.
(C)–(D) Morphology of generated riPSCs (passage P0); bright field and fluorescent field (C). ALP staining after clonal passage (D).
