Moreover, western blot analysis of the lung tissue from BM‐MSC transferred stroke mice (3d after tMCAO) displayed increased expression of migrasome markers of C3ORF64, PIGK, and PGCP, while the level of exosome markers including HSP70 and HSP90 was stable comparing with the PBS‐injected controls (Figure 4H). This evidence concerns the gene EOGT and stroke disorder.
