Our previous study showed that in mice with STZ‐induced type I diabetes, colon lengthening significantly decreased colon motility and reduced colon transit and that colonic PDGFRα+ cells were significantly hyperplastic and hyperfunctional; however, the mechanism underlying diabetes‐induced PDGFRα+ cell proliferation was unclear (Lu et al., 2017; Song et al., 2018). Here, PDGFRA is linked to type 1 diabetes mellitus.
