Figure 3From: Human Wharton’s jelly mesenchymal stem cells promote skin wound healing through paracrine signalingWharton's jelly-derived mesenchymal stem cell conditioned medium accelerates wound closure in vitro . (A), (B) Scratch wound assay was performed to examine migration properties of Wharton's jelly-derived mesenchymal stem cell conditioned medium (WJ-MSC-CM)-treated and untreated normal skin fibroblasts. The treated group showed significantly enhanced migration rates and coapted wound borders faster than the control group. *P ≤ 0.05.Back to article page
