RNA sequencing
RNA from isolated early retinal progenitors (mCherry-positive) derived from retinal organoids, embryonic stem cells at the origin of these progenitors, and photoreceptor cells from mice (FVB-WT from Charles-River) (n = 3 for mCherry-positive and mES cells, n = 5 for photoreceptors) were isolated with a Macherey-Nagel NucleoSpin RNA/Protein kit (740933.50) and sequenced.
