Single-cell RNA sequencing data from hiPSC disease modeling of Loeys-Dietz Syndrome (LDS)

For in vitro disease modeling of LDS, we used healthy donor cells (TGFBR1+/+), and generated heterozygote (TGFBR1A230T/+), and homozygote (TGFBR1A230T/A230T) knock-in clones using CRISPR-Cas9 gene editing. We also generated hiPSC from peripheral blood mononuclear cells harvested from an LDS patient, and corrected the mutation in the patient-derived hiPSC. To address the lineage-specific effects of TGFBR1A230T, and SMAD3c.652delA/+, hiPSC were differentiated into cardiovascular progenitor cell-derived smooth muscle cells (CPC-SMC), and neural crest stem cell-derived smooth muscle cells (NCSC-SMC) using in vitro differentiation protocols. We performed large-scale single cell profiling of the resulting CPC-SMC and NCSC-SMC. Overall design: Using an automated microwell array platform and mRNA capture beads, we generated single-cell RNA-seq profiles of cultured CPC-SMC and NCSC-SMC derived from hiPSC.
