Distribution of doublecortin in the developing retina of birds: A comparative analysis

open access: yesThe Anatomical Record, EarlyView.
Abstract The avian retina presents an elegant and highly accessible model for investigating the spatial and temporal dynamics of neurogenesis within the central nervous system. In recent years, the microtubule cytoskeleton has emerged not merely as a structural scaffold, but as a dynamic regulator of the transition of a morphologically homogeneous pool
