Reprogramming of genetically unmodified mouse embryonic fibroblasts into embryonic stem-like cells
Outline of the mouse embryonic fibroblasts (MEF) reprogramming protocol.
- 2.5×105 MEF cells were plated in two 100 mm dishes
- were infected with Sox2, Klf4, c-Myc and Oct3/4 virus
- Cells in dish 1(blue arrow) were passage on day 8 after infection
- ES-like colonies form 4 days later
- Cells in dish 2 (red arrow) were AP staining positive on day 14 and the colonies were counted.

(C) Morphology of ES-like colonies on day 6 after passage. (D) AP positive colonies on day 14 post infection. (E) Estimated reprogramming efficiency of genetically unmodified MEF into AP positive ES-like cells 16 days post infection.
