To access the data, click or select the words “Appendix 15.” A. Representative image of hIPSC-derived PhRs at D50 of differentiation in Exp 3. Scale bar: 20 μm. B. Magnified and annotated view of panel A, showing cells in a linear arrangement with distinguishable nuclei (Nu), inner segments (IS), mitochondria (m), calyceal processes, defined Golgi apparatus, telodendria, and putative opsin-carrying vesicles (OCV). Scale bar: 10 μm. C. Image of hIPSC-derived PhRs at day 64 of differentiation in Exp 3, showing similar morphology to panel B, with abundant mitochondria (m) and visible nuclei (Nu). D. Representative image of 661W photoreceptor-like cells used for morphological comparison.
