“…In E16.5, we detected that clusters 0, 2 and 6 expressed fibroblasts markers of Twist2 and Col1a1 , cluster 1 expressed keratinocytes markers of Krt14 and Krt15 , cluster 3 and 9 expressed blood vessels markers of Kdr and Flt4 36 , cluster 4 expressed lymphocytes markers of Cpa3 39 and Ccr8 40 , cluster 5 expressed macrophages markers of Cd86 and F13a1 41 , cluster 7 expressed muscle markers of Myod1 42 and Myog 43 , cluster 8 expressed schwann markers of Gpr17 and Lims2 6 , cluster 10 expressed melanocytes markers of Tyr 6 and Dct 44 , cluster 11 expressed melanocytes markers of Ctsd 6 and Lamp1 45 . In P0, we detected that clusters 0, 2, 3, 7 and 9 mainly expressed fibroblasts markers of Twist2 and Col1a1 , clusters 1, 4, 5, 6 and 8 expressed keratinocytes markers of Krt14 and Krt15 , cluster 10 expressed melanocyte markers of Pax3 6 and Plp1 46 , cluster 11 expressed blood vessels markers of Kdr and Cdh5 30 , whereas the cells of cluster 12 expressed pericytes markers of Ebf2 30 and Rgs5 47 . According to the gene activity of marker genes, the cells were classified into 6, 8 and 5 populations, respectively.…”
