Micro-CALI of L1 causes neurite retraction. Micro-CALI of L1 causes neurite retraction but does not inhibit filopodial motility. A chick DRG growth cone was incubated with MG-labeled 8D9, and motility was observed by time-lapse video microscopy before laser irradiation (A). Laser irradiation of the growth cone (B, C) caused neurite retraction (D) after 10 min and subsequent recovery and growth along a different path (E, F) after 30 min. Filopodial motility is not affected. Scale bar, 10 μm.
