Latex bead labelling and comparative immunofluorescence analysis of the p62 subunit of the TFIIH was performed as described previously [16,17] using primary mouse
embryonic fibroblasts at passages 2 — 5.

Vermulst's study looked only
at tissues from the heart, brain, and
embryonic fibroblasts.
In 1963 Pietro Angeletti and one of us (Levi Montalcini), who were then
at the Istituto Superiore di Sanità in Rome, dissected sensory and sympathetic ganglia into their cellular components: neurons, glial cells (which support and nourish the neurons) and
fibroblasts (
embryonic connective - tissue cells).
FINDINGS The researchers identified 32 known imprinted genes, but no new ones, implying that the list of imprinted genes in the mouse —
at least in
embryonic fibroblasts — is nearly complete, says Morison, who was not involved in the study (Nucleic Acids Res, 42:1772 - 83, 2014).
For instance, MEF cells are usually made of
fibroblasts from the mouse embryos
at embryonic day 13.5 and only cells
at early passages (p2 to p3) are used as feeders for derivation and culture of
embryonic stem (ES) and iPS cells.
The skin biopsies were washed in Ca / Mg - free Dulbecco's Phosphate Buffered Saline (PBS, Invitrogen, Carlsbad, CA, http://www.invitrogen.com) and minced into approximately 12 smaller pieces before being seeded onto gelatin - coated 6 - well cell culture plates (Corning Enterprises, Corning, NY, http://www.corning.com) containing mouse
embryonic fibroblast (MEF) media consisting of Dulbecco's Modified Eagle Medium (DMEM) supplemented with 10 % fetal bovine serum (FBS, Invitrogen) and 100 IU / ml penicillin - streptomycin (Invitrogen), and cultured
at 37 °C in a 5 % CO2 incubator.
