Johns Hopkins physicians report success in a small study of
a modified skin biopsy that hastens the earlier diagnosis of an inherited and progressively fatal nerve disease and seems to offer a clearer view of the disorder's severity and progression.
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.
