Figure 5. Retina from a transgenic line 98 (Tg98) mouse and a wild-type littermate

Cone photoreceptor cells that contain round nuclei with several clumps of heterochromatin surrounded by pale stained euchromatin were not present in the remaining (at postnatal day 21) photoreceptor cells in both the central and peripheral retinas of Tg98 mouse. OS, outer segment; ONL, outer nuclear layer; INL, inner nuclear layer; C, cone photoreceptor cell; Cr, central retina; Pr, peripheral retina. H & E-stain; the bar in the lower right represents 30 mm.
