expresses expresses amacrine cell displaced amacrine cell Displaced amacrine cells are a subset of Sox2 expressing amacrine cells. inverted amacrine cell A subpopulation of amacrine cell that migrate further than other amacrine cells, and come to lie basal to the inner plexiform layer (IPL) in the ganglion cell layer. Displaced amacrine cells still have their neurites extending apically into the IPL, and therefore exhibit an inverted polarity with respect to the other amacrine cells. dACs transcription factor SOX-2
