Mechanism vital to keeping blood stem cells functional uncovered

Hematopoietic stem cells, that form mature blood cells, require a very precise amount of protein to function – and defective regulation of protein production is common in certain types of aggressive human blood cancers. ...

Scientists isolate cancer stem cells using novel method

Researchers at The University of Texas at Dallas have devised a new technique to isolate aggressive cells thought to form the root of many hard-to-treat metastasized cancers—a significant step toward developing new drugs ...
