To investigate BM-MSC and Migrasome-mediated effects on post-stroke TEC, we subsampled and reanalyzed TEC clusters (Fig. 5B), categorizing them into seven subsets: cortical TEC (cTEC, high Prss16), medullary TEC I (mTECI, high Ccl21a), medullary TEC II (mTECII, high Aire), mTECIII (high Ly6d), neuroendocrine-like TEC (TECneuro, high Car8), tuft-like TEC (TECtuft, high Avil), and goblet cell-like TEC (TECgoblet, high Wfdc2) (Fig. 5B). Here, PRSS16 is linked to Stroke.
