Fig. 2: Cell-type annotations in a single-cell atlas of the sleeping fruit fly.

a, t-Distributed stochastic neighbor embedding (t-SNE) plot of the entire dataset of 106,762 single cells with annotated clusters and expression of key marker genes of glial and neuronal cell types used to annotate the clusters. b, Marker gene expression across most of the clusters annotated in a. 5-HT, 5-hydroxytryptamine (serotonergic) neuron; adPN, anterodorsal projection neuron; ALG, astrocyte-like glia; CXG, cortex glia; EG, ensheathing glia; PB, protocerebral bridge neuron; PG, perineurial glia.
