Stem cell signaling protein spurs cancer spread

Investigators at the University of California, San Diego School of Medicine have published a study on Nature Genetics that details how they linked a protein called Lis1, which could be associated with a vital stem cell signal to cancer growth.  Lis-1 is essential to hematopoietic stem cell (HSC) function and blood formation. In this study, when researchers first deleted the Lis1 protein from mouse HSCs, they …
