title: Neurite outgrowth is enhanced by conditioning factor(s) released from central ganglia of Aplysia californica.
abstract: Single neurons of Aplysia californica were cultured on control and conditioned medium-treated cover slips (CM, derived from central ganglia of Aplysia) and fed with L-15 medium plus 20% hemolymph. After 5 h 36.9 +/- 3.3% of all neurons plated on CM-treated cover slips sprouted, whereas only 22.9 +/- 2.7% sprouted in the control group. After 24 h the average neurite length in the presence of putative conditioning factor(s) was 621 +/- 42 microns versus 411 +/- 20 microns in control, but the number of primary processes was the same (4.3 +/- 0.5 versus 4.2 +/- 0.9).
