Immunohistochemical Analysis of Postburn Scars following Treatment Using Dermal Substitutes

Comparison of α-SMA stroma. α-SMA of the normal (a), STSG (b), FTSG (c), Matriderm® (d), and AlloDerm® (e) group; 400x magnification, 100 μm scale bar; immunostaining technique; Myofibroblasts express α-SMA, and persistence of myofibroblasts may lead to excess scarring, which impairs function and aesthetics. There was a significant increase in α-SMA in the STSG, FTSG, and AlloDerm® compared with the normal and Matriderm® groups.
