Gelsolin deficiency impairs neural progenitor cell migration in vitro. A–D, Representative micrographs illustrating slowed migration of Gsn−/− compared with Gsn+/+ cells out of neurospheres seeded in Matrigel during a 20 h period. The greatest distance a cell had migrated out of the sphere at 20 h was recorded using LAS software. Scale bar: (in C) 50 μm. Quantitative data of migration distances in the Matrigel assay are given in the text.
