Nutritional requirements of animal cells

The mechanisms by which the growth supplements in serum-free medium act are still not understood. In order to achieve an understanding of the biochemical basis for the hormonal and growth factor requirements of animal cells, the basic mechanism of action of hormones and growth factors must be determined. The biochemical basis for the nutritional requirements of animal cells can only be determined when we have an understanding of the metabolism of the different types of animal cells.
