General description

PMEF-NL-P1 are low passage neomycin resistant Primary Mouse Embryo Fibroblasts (PMEFs) isolated from FVB mouse embryos at day 13. The cells have NOT been mitotically arrested. PMEFs are the traditional feeder cells used to support the growth of undifferentiated mouse and human pluripotent stem cell cultures. Additionally, low passage primary cultures of fibroblasts have a high proliferative capacity and can be used for reprogramming. It is known that cellular reprogramming efficiency declines with each passage, presumably due to lowered proliferative capacity of PMEFs at later passages. These untreated PMEF cells are high quality, low passage (P1) mouse fibroblasts that have been successfully reprogrammed into iPS cells with high efficiency. They can be used to study the mechanisms of reprogramming or be further expanded and treated with γ-irradiation or mitomycin-C to make growth arrested feeder cells. See Murine Embryonic Stem Cell Culture Manual for complete culture and media for PMEF cells.
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.

Mouse Embryonic Fibroblasts (MEF Feeder Cells)

Mouse embryonic fibroblasts (MEFs) serve as a feeder layer for both mouse and human embryonic stem cells (ES cells) and induced pluripotent stem cells (iPSCs).

The Genetically Modified Mouse: An Indispensable Tool for Disease Modeling

"As transgenic mouse core laboratories know well, mouse models are a powerful means of determining the function of mammalian genes in the context of whole organisms—especially since over 95% of the mouse genome is similar to the human genome. However, you may not know that: 1. Laboratory mouse strains are descended from ancestors in modern-day Pakistan. 2. The first inbred strain of lab mouse was created in 1909. It was named DBA for its coat color: dilute brown non-agouti. 3. There is a mutant mouse actually named“Bad Hair Day” (Bhrd). Someone get this little guy a stylist! 4. Male mice, when treated with anticancer drugs, have been shown to pass on DNA instability to their offspring. 5. The founder of Jackson Laboratories, C. C. Little, once had lunch with Walt Disney to request that an animated film be created linking Mickey Mouse and the laboratory mouse. The request was denied."
