Figure Lengend Snippet: Generation and characterization of hPSC-derived neural crest pericytes (A) Schematic of differentiation of neural crest pericytes (NCC-PCs) from hPSCs. (B, D, F–H) Bulk RNA sequencing was performed on hPSCs, hPSC-derived neural crest cells (NCC), hPSC-derived NCC-PCs (NCC-PC), hPSC-derived mesoderm pericytes (M-PC), or primary CNS pericytes (Primary PC). H1 or iPS11 stem cells were used for all differentiations. All bar graphs show the mean value of three biological replicates; error bars show standard deviation. (B) Normalized RNA expression of PDGFRb. (C) Expression of PDGFRb quantified by flow cytometry on H1 or iPS11 hPSCs, NCCs, and NCC-PCs. (D) Normalized RNA expression of CSPG4 (NG2). (E) Immunofluorescence images of H1 hPSC-derived NCCs or H1 hPSC-derived NCC-PCs stained with an antibody directed against NG2. Scale bars = 100um. (F) Normalized RNA expression of CD44 (G), normalized RNA expression of CD146, and (H) normalized RNA expression of CD13. (I) Expression of CD13 quantified by flow cytometry on H1 or iPS11 hPSCs, NCCs, and NCC-PCs. (J) TEER values of H1 hPSC-derived BMEC-like cells plated in Transwell plates with or without H1 hPSC-derived NCC-PCs plated in the lower chamber. TEER was measured beginning at 0 h after the initiation of co-culture. TEER values were measured in three independent experiments. The fold change in TEER values from 0 to 48 h after the initiation of co-culture was quantified for each experiment and compared using an unpaired t test.
