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
Buyer's Guide to Protein Transduction Reagents

Six years ago, when John Tinsley's postdoctoral advisor at Texas A&Mtold him to find a protocol to introduce proteins into coronary endothelial cells, he couldn't find one in the literature. Tinsley tested a variety of commercial DNA transfection reagents, found one that worked for proteins, and has been using it since then.Tinsley's experience would be a lot different today. No longer must researchers rely on tedious and toxic procedures, or on proprietary reagents designed specifically for
