Figure 9. Timeline for cell genesis in the vertebrate retina.

Figure 9

Sequence of cell genesis in the vertebrate retina, schematized here for the mouse. Horizontal cells (HCs), cone photoreceptors (cone) and retinal ganglion cells (RGC) are the first cells to be generated. Amacrine cell (AC) genesis follows, with their peak production occurring around embryonic day 16 (E16). Rod photoreceptors (rod) have a protracted period of genesis beginning before birth and continuing until a week after birth. Bipolar cells (BC) and Müller glial cells (Glia) are produced postnatally (P) until about a week after birth (summarized from Marquardt and Gruss, 2002; Rapaport et al., 2004; Young, 1985). Bars demonstrate the progressive increase and later decrease in neurogenesis as indicated by the intensity gradient.
