The flow cytometric assay displayed a higher ratio of CD206+ cells in macrophages derived from IH exosomes or RA miR‐106a‐5p mimics exosomes group than RA exosomes group, which was reversed by inhibition of miR‐106a‐5p in IH exosomes (Figure 11a). This evidence concerns the gene MRC1 and isolated hemihyperplasia.
