Other Notes

These PMEF cells were isolated from CF-1 mouse embryos at day 13 and mitotically inactivated by treatment with irradiation. The cells can be directly plated onto gelatin coated (Cat. No. ES-006-B) culture vessels. These cells are from passage 3. 5-6 x 106 cells will produce the appropriate density feeder layer on the following tissue culture vessels:

• 6 x 60mm dishes
• 2 x T75 flasks
• 2 x 6 well plates

Refer to Murine Embryonic Stem Cell Culture Manual for complete culture protocols and media formulations for PMEF cells.

Background information

The EmbryoMax range of PMEF cells provides researchers with a convenient solution for ES cell culture by eliminating the need for time consuming feeder cell isolation and preparation. Many embryonic stem cell culture protocols necessitate the use of primary mouse embryo fibroblast (PMEF) cells. In these protocols, ES cells are typically cultured on a monolayer of PMEF feeder cells. Feeder cells perform two important roles in stem cell culture: they secrete several important growth factors into the medium, which help maintain pluripotency, and they provide a cellular matrix for ES cells to grow.
