How Cells Find Their Way
Laura Defrancesco | Sep 2, 2001 | 5 min read
Organisms need to sense their environment. By sensing, they can develop, heal wounds, protect against invaders, and create blood vessels. Chemotaxis, or directional sensing, allows cells to detect chemicals with exquisite sensitivity. Some chemotactic cells can sense chemical gradients that differ by only a few percent from a cell's front to its back. Although discovery of the molecule types involved in chemotaxis, as with other kinds of cell signaling events, has mounted, the details of how thi

A Living Legacy At the birthplace of stem cell research, the next generation of scientists continues to advance the field. By Megan Scudellari In Toronto’s downtown Discovery District, world-class stem cell researchers populate the buildings like athletes at the Olympics. On University Avenue, Andras Nagy, a renowned innovator in induced pluripotent stem (iPS) cells, works at the Samuel Lunenfeld Research Institute, housed within the towering Mount Sin
Light Microscopy Enables Scientists to Peer Inside Cells In Real Time
Holly Ahern | Jan 21, 1996 | 9 min read
Although the laws of physics dictate how much an object can be magnified and still clearly seen, scientists continue to expand their view of the microscopic world beyond the cellular level. New light microscopy methods and technology have made it possible for scientists to view previously undetectable tiny structures inside of cells, and to examine such objects in real time as cells carry out their activities. "New microscopy techniques, particularly those involving fluorescence microscopy and
