Immunohistochemistry was performed on Pou4f2^Cre/+ Ai9 retinas to determine which cells types within the retina express Pou4f2^Cre. This table summarizes Figure 3 and Figure 4 and contains markers not shown (IBA-1, GFAP, GS isolection-B4). *1 out of 34 mice contained sparsely labeled Müller glia, where columns of cells expressed tdTomato. Abbreviations: ACs—amacrine cells, BCs—rod bipolar cells, HCs—horizontal cells, RGCs—retinal ganglion cells, TH—tyrosine hydroxylase, PKC—protein kinase C, GS—glutamine synthetase.
