Inhibition of keloid by 32P isotope radiotherapy through suppressing TGF-β/Smad signaling pathway

class="figure-viewer-img"

Figure 1. Both 32P isotope injection and skin path significantly reduce the size of keloid. (A) 32P isotope injection and skin path significantly reduced the size of keloid (n=6); (B) HE staining was performed to investigate the histological changes (n=3); (C) Masson's trichrome staining was performed to investigate the collagen deposition (n=3). * indicates p <0.05.
