FEATUREThe Ecology of Tumors   Courtesy of Nasa Ames Research CenterBy perturbing the microenvironment, wounds and infection may be key to tumor development.BY PARAIC A. KENNY, CELESTE M. NELSON, AND MINA J. BISSELLNo tumor is an island. Chemical and physical forces exerted by the diverse cellular populations that surround a tumor - its so-called microenvironment - shape development and progression. Manipulating these 'ecologi

Date: June 22, 1998 Insect Cell Culture Media, Suppliers of Primary Cell Culture Media Advantages for Protein Expression Studies Since the mid-1950s cultures of insects--cockroaches, fruit flies, and leafhoppers, to name a few--have been the object of quiet study by physiologists and cell biologists. But along came genetic engineering and suddenly insect cultures have been put in the spotlight since they provide advantages over both bacterial and mammalian systems for recombinant protein prod

Old ovaries, new eggs
Tia Ghose | Apr 11, 2009 | 2 min read
Are female mammals born with all the eggs they'll ever have, or can they produce new eggs into adulthood? The question has been vociferously debated, but now, a study published online in Nature Cell Biology today (April 12) reports that at least in mice, adult female ovaries have a store of stem cells that have the potential to generate new eggs. Human oocyte Image: Wikimedia CommonsThe study "is a huge step in quelling this debate," Jonathan Tilly, a reproductive biologist at Harvard Medical
