Aggressive Melanoma Cells Form Blood Vessels In Ischemic Tissue
Cancer researchers at the University of Iowa and Loyola University in Chicago have demonstrated that aggressive human melanoma cells form new blood vessels when placed in living tissue that is in need of a blood supply. The researchers also found that these aggressive melanoma cells make the same molecules that direct the formation of new blood vessels in embryos. The results may have implications for the diagnosis of aggressive tumor cells and for new therapeutic strategies to treat cancers. more

Adult Bone Marrow Stem Cells Can Become Blood Vessels
Researchers at the University of Minnesota Stem Cell Institute (SCI) have demonstrated, for the first time, the ability of adult bone marrow stem cells to expand in vitro as endothelial cells (which line blood- and lymphatic vessels) and then engraft in vivo and contribute to new growth of blood vessels (neoangiogenesis). The findings will be published in the 01 February 2002 issue of the Journal of Clinical Investigation. more

Understanding Of Complex Virus Nano-Machine For Cell Puncturing And DNA Delivery Could Lead To A New Class Of Antibiotics
Researchers have learned how the bacterial virus, bacteriophage T4, attacks its host, the E. coli bacterium. This discovery could eventually lead to a new class of antibiotics. Funded primarily by the National Science Foundation and published in the 31 January 2002 issue of the journal Nature, the research describes for the first time how the virus uses a needle-like, biochemical puncturing device to invade its host. more
