Two integral components of the machinery that causes cells to move were teased apart by cell biologists at The Johns Hopkins University. Their discovery shows that cellular projections, which act as hands to help a cell "crawl," are apparently always initiated by a network of message-relaying proteins inside the cell. It was already known that in directional movement, the network is activated by sensor proteins on the cell's surface in response to external cues. They now know ...Tuesday, 29 October 2013
John Hopkins Researchers Find That 'Random' Cell Movement is Directed from Within
Two integral components of the machinery that causes cells to move were teased apart by cell biologists at The Johns Hopkins University. Their discovery shows that cellular projections, which act as hands to help a cell "crawl," are apparently always initiated by a network of message-relaying proteins inside the cell.
