To study the development of human retina, we used single cell RNAseq at key fetal stages and followed the development of the major cell types, as well as populations of transitional cells. We also analyzed stem cell (hPSC)-derived retinal organoids; although organoids have a very similar cellular composition at equivalent ages to the fetal retina, there are some differences in gene expression of particular cell types. Moreover, the inner retinal lamination is disrupted in more advanced stages of organoids when compared with fetal retina. To determine whether the disorganization in the inner retina was due to the culture conditions, we analyzed retinal development in fetal retina maintained under similar conditions. These retinospheres develop for at least 6 months, displaying better inner retinal lamination than retinal organoids. Our scRNAseq comparisons between fetal retina, retinal organoids and retinospheres provide a new resource for developing better in vitro models for retinal disease.
