A serum-free medium formulation supporting growth of human umbilical cord vein endothelial cells in long-term...

A serum-free medium formulation - TUD-1 - was developed supporting growth of HUVEC in tissue culture. Special features of the basal medium formulation are highly elevated levels of glutamine and serine as well as the inclusion of N-acetylcysteine and phosphoascorbic acid. The cellular mitogenic needs are satisfied by bFGF, VEGF, EGF and liver growth factor. Further hormone supplementation consists of insulin and hydrocortisone. A protocoll for serum-free passage of HUVEC was established for serum-free long-term cultivation of freshly isolated HUVEC for up to 20 cumulative population doublings without significant differences in final cell density compared to controls cultivated with serum.
