1. A chemically defined medium for eukaryotic cell culture, comprising water, at least one carbon source, one or more vitamins, one or more salts, one or more fatty acids, one or more buffer components, selenium, at least one substance of the group of Functional Inhibitors of Acid Sphingomyelinase (FIASMAs) and at least one polypeptide of the TGF-β superfamily with the ability to inhibit stem cell differentiation,
wherein the chemically defined medium is free of FGF-2,
wherein the chemically defined medium is completely devoid of human- or animal-derived substances,
wherein the ratio between said FIASMA and said at least one polypeptide of the TGF-β superfamily is from 400:1 to 2000:1,
wherein the concentration of the at least one FIASMA is in the range of 0.1 mg/L to 10 mg/L, and
wherein the concentration of the at least one polypeptide of the TGF-β superfamily is in the range of 0.2 μg/L to 20 μg/L.
