FEATUREThe Ecology of Tumors Stem cells for brain cancer BY PETER B. DIRKSNeural stem cell biology took off in 1992 when Brent Reynolds and Samuel Weiss, working at the University of Calgary, discovered that culturing mammalian brain cells in serum-free conditions (in EGF and bFGF), yielded clonally derived colonies of undifferentiated neural cells (neurospheres). This culture system demonstrated that cells within these colonies showed cardinal pr

Leukemia and Cancer Stem Cells
Irving Weissman and Michael Clarke | Apr 1, 2006 | 4 min read
FEATUREThe Ecology of Tumors Leukemia and Cancer Stem Cells BY IRVING WEISSMAN AND MICHAEL CLARKECancers and normal tissue stem cells have much in common: Both have self-renewal capacity, and both develop into differentiated progeny. But do true cancer stem cells exist? We believe that they do and that this realization will have a major impact on the understanding and treatment of cancers. Putative cancer stem cells can be recognized by three attr
Making Things Grow: Insect Cells, Stem Cells, and Primary Cell Lines All Pose Challenges for Cell Culturists

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
