The term "cell culture" brings to mind several cliches--"if it ain't broke, don't fix it" and "the more things change, the more they remain the same," to name a few. While the requirements of cells growing in culture haven't changed over the years, better understanding of the precise combinations of nutrients, growth factors, attachment factors, and the like necessary for a cell's life apart from the organism has eased cell culture, always an integral part of the cell biology laboratory.

"Lots of companies come out with media or reagents for this or that, and make a big splash, but they're all basically derivatives of traditional products," says Hayden Coon, a former National Institutes of Health re-searcher who is the founder of Human Cell Therapies Inc. of Chebeague Island, Maine.
