Coat the plates with Matrigel prior to plating the cells. It worked for
SY5Y and PC12 cells. Make diluted Matrigel solution (1:20 with water),
vortex until totally dissolved, totally cover plate well with solution,
allow to sit for 3hr. under hood, aspirate off all solution, allow to dry
overnite in hood. With above cells, it takes 5-10 days but extensive
neurite outgrowth is very evident because RA slows cell proliferation down
