The invention discloses a human adipose-derived stem cell serum-free basic medium. The medium uses a serum substitute, and is composed of a high glucose type DMEM basic medium, human serum albumin, transferrin, taurine, reduced glutathione, ceruloplasmin, L-ascorbic acid-2-sulfate, alpha-tocopherol succinate, linoleic acid, alpha-ketoglutarate and selenium. The serum-free basic medium can exempt potential threats caused by animal serum in conventional serum-containing mediums to human health, and the adipose-derived stem cells cultured by the medium is more suitable for clinical application.
