Formation, transport, contraction, and disassembly of stress fibers in fibroblasts.

Abstract

Swiss mouse 3T3 fibroblasts grown on a solid substrate in the presence of 10% serum exhibit cell movement, organelle transport, and cytokinesis. When the serum concentration in the culture medium is decreased to 0.2% for 48 h the serum-deprived cells virtually stop locomoting, spread, decreased organelle transport, and exhibit extensive arrays of stress… (More)
