Single-cell gene expression analysis using the Fluidigm dynamic array. Single-cell gene expression profiling using Fluidigm dynamic arrays was performed. Heat maps depict the expression of genes differentially expressed between iKC6 (transgene residual) and iKC6-R1 (transgene-free) hiPSCs and primary human keratinocytes (control). Rows represent individual cells, and columns represent the evaluated genes. Genes highly expressed are shown in white, and genes with low expression are shown in red. Abbreviations: AFP, α-fetoprotein; dNp63, Δ N p63; iKC, induced keratinocyte; INV, involucrin; ITGA6, α6 integrin; ITGB4, β4 integrin; KRAT, keratin; PKC, primary human keratinocytes from neonatal male skin.
