title: Growth cones in developing cultured cortical neurons.
abstract: Large numbers of growth cones were present in 6-day-old primary cultures of cerebral hemispheres from fetal rats. The average size of the growth cones was 24 by 28 microns. Many of these growth cones had both veil-like lamellipodia and filopodia. A few cones remained in 21-day-old cultures. These also had lamellipodia and filopodia. Ganglioside GM1 was present in both 6-day-old and 21-day-old cultured growth cones.
