To understand the MF subtype specification process, we generated an immune cell transcriptomic atlas using droplet-based single-cell 3′ RNA-Seq in CD45+ cells FACS isolated from CTX-injured TAs at days 1 and 2 and combined datasets from peripheral blood mononuclear cells (PBMCs) and day 4 after CTX (7) (Figure 2A). Here, PTPRC is linked to cerebrotendinous xanthomatosis.
