Cell-intrinsic drivers of dendrite morphogenesis
... In addition to controlling the specificity of dendrite patterning, cell-intrinsic mechanisms also coordinate the timing of dendrite morphogenesis. Neonatal RGCs rapidly lose the ability to extend axons upon the onset of dendrite development (Goldberg et al., 2002; Goldberg, 2004). Furthermore, RGCs ...
