tdTomato cells cluster into distinct groups. The tdTomato+ cells were clustered using Pearson correlation with average linkage and 3 separate clusters of RGCs were identified (A). A heatmap showing the genes expressed highly by cells in those clusters (B), with red signal indicating high expression of the gene in a particular cell, and black signal indicating the absence of expression.
