Supplementary Figure 5: Single-cell RNA Sequencing and IHC examination of ALK in human neural development and immature neural cells. A. 2D representation of human brain cell subtypes (48 samples) during cortex development using a single cell RNA-seq atlas (cortex-dev.cells.ucsc.edu) shows that ALK transcript appears to be enriched in a certain cell type. Color-coded by ALK gene expression (beige to red) and age in weeks (rainbow).B. ALK-stained sagittal section of normal human cerebellum at 15 postconceptional weeks (pcw).C. ALK-stained sagittal section of human fetal neural stem cell pellets at 13 postconceptional weeks (pcw).D. ALK-stained sagittal section of human fetal neural stem cell pellets at 15 postconceptional weeks (pcw).
