  "abstract": "A serum-free, synthetic tissue culture media is described which is completely defined chemically. The two media described can be used for growing all types of human or animal cell lines in tissue culture without addition of any protein, amino acids, hormones, sources of energy, salts, vitamins, etc. with normally used procedures and methods. The media do not require any supplementation with fetal calf serum to support growth of neural cells.",
