Thread Embedding Acupuncture Inhibits Ultraviolet B Irradiation-Induced Skin Photoaging in Hairless Mice

<div>In situ zymographic analysis for MMP-9 activity in dorsal skin of TEA-treated mice against UVB-induced skin damage. (a) Images of gelatinoylysis/MMP-9 and (b) its higher magnification. Degradation of collagen by gelatinases was detected as fluorescence. TEA treatment significantly suppressed gelatinoylysis and MMP-9 expression in the dermal region. TEA, thread embedding acupuncture; MMP-9, matrix-metalloproteinase-9; UV, ultraviolet B. Scale bars = 200 <i>μ</i>m (a) and 100 <i>μ</i>m (b).</div>
