Adipose-Derived Stem Cell Exosomes Antagonize the Inhibitory Effect of Dihydrotestosterone on Hair Follicle Growth by Activating Wnt/<i>β</i>-Catenin Pathway

<div>ADSC-Exos antagonizes the inhibitory effect of DHT on hair follicle growth. (a) CCK-8 absorbance values of ADSC-Exos and/or DHT treated DPCs after 72 hr. (b) Scratch experiment of ADSC-Exos and/or DHT treated DPCs for 0, 12, 24, and 48 hr, scale bar: 100 <i>μ</i>m. (c) Quantitative analysis of scratch area in (d) Hair follicle growth graph, <i>n</i> = 6. (e) Mean length of hair shaft increase (mm), <i>n</i> = 6. (f) Morphology of hair follicle growth at 0, 2, 4, 6, 8, and 10 days after ADSC-Exos and/or DHT treatment, scale bar: 500 <i>μ</i>m. (g) Ki67 expression of hair follicles in each group, scale bar: 100 <i>μ</i>m. (h) The proportion of Ki67+ hair matrix keratinocytes in each group. <span class="nowrap"><svg height="12.8952pt" id="M16" style="vertical-align:-0.6370001pt" version="1.1" viewbox="-0.0498162
