(a) HE and Masson staining of the wound tissues from control, NH (0), and NH (500) group. (b), (c) The wound gap and granulation thickness of the wound tissues from control, NH (0), and NH (500) groups. The wound gap was marked by two black dashed lines, and the thickness of the granulation was marked by a black arrow in (a). The scale bar is 500 μm in HE stains and 50 μm in Masson stains in (a).
