ABSTRACT:
A mixture or substance having a spheroid-forming activity is obtained by heat treating fetal calf serum at a temperature and for a period sufficient to impart spheroid-forming activity. Introduced into cell culture, the substance or mixture so obtained causes cells to grow in three-dimensional cultures as opposed to mono-layer. Also disclosed are kits for the production of said mixture or substance and further uses of said mixture or substance.
