The motivation behind this activity varies-some scientists want to study the effects of hormones on target cells in vitro, and to do this, the media need to be hormone- and hence serum-free. Others want to understand how the growth of cells is regulated and are using serum stimulation of growth as a paradigm to gain this understanding. And still others just want to create reproducible and uncomplicated experimental culture systems, not dependent on...
