    Localization of PTK2 , HDAC5 , and HDAC4 gene expression in modulated SMC subtypes using an integrated human atherosclerosis reference. Uniform Manifold Approximation and Projection (UMAP) embeddings from an integrated human atherosclerosis single-cell RNA-seq reference dataset (see Methods ), highlighting ( A ) PTK2 , ( B ) HDAC5 , and ( C ) HDAC4 normalized gene expression. Individual sequencing libraries across four studies were harmonized after QC and batch correction with reciprocal PCA (rPCA). A broad SMC cluster was annotated using transfer learning with cell labels from the Tabula Sapiens vasculature subset. SMC subtypes were further annotated by extracting gene modules from a scRNA meta-analysis of murine SMCs (contractile SMC, transitional SMC, fibromyocyte, and fibrochondrocyte) and calculating their enrichment in cells within the main SMC cluster. PTK2 and HDAC5 expression were enriched in transitional SMCs and fibromyocytes.

    Localization of PTK2 , HDAC5 , and HDAC4 gene expression in modulated SMC subtypes using an integrated human atherosclerosis reference. Uniform Manifold Approximation and Projection (UMAP) embeddings from an integrated human atherosclerosis single-cell RNA-seq reference dataset (see Methods ), highlighting ( A ) PTK2 , ( B ) HDAC5 , and ( C ) HDAC4 normalized gene expression. Individual sequencing libraries across four studies were harmonized after QC and batch correction with reciprocal PCA (rPCA). A broad SMC cluster was annotated using transfer learning with cell labels from the Tabula Sapiens vasculature subset. SMC subtypes were further annotated by extracting gene modules from a scRNA meta-analysis of murine SMCs (contractile SMC, transitional SMC, fibromyocyte, and fibrochondrocyte) and calculating their enrichment in cells within the main SMC cluster. PTK2 and HDAC5 expression were enriched in transitional SMCs and fibromyocytes.
