Type II progenitor cluster contains type II neuroblasts that show candidate temporal transcription factors. A UMAP of type II progenitors highlighted. B UMAP of cluster from 1h-48h. C UMAP of sub clustered type II progenitors. D UMAP of type II neuroblasts from 1h-48h. E Dot plot of validated markers between type II neuroblasts and nonannotated progenitors. F Dot plot of top cluster defining genes and validated markers for type II neuroblasts. G Dot plot of differentially expressed TTFs between 24h alh and 48h type II neuroblasts
