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
How Well Do Mice Model Humans?
Ricki Lewis | Oct 25, 1998 | 8 min read
STRIKING RESEMBLANCE: James Croom, who studies Down syndrome mice at North Carolina State University, says the animals are providing valuable information useful to humans. When a page-one article in the May 3, 1998, Sunday New York Times portrayed angiogenesis inhibitors that fight cancer in mice as being possible just around the corner for humans, criticism for raising false hopes erupted. Merely 10 weeks later, however, when researchers from the University of Hawaii reported cloning the fi
