Fig. 3: Abundance of LOX/LOXL enzymes in human skin dermis and scar.

qPCR of LOX family of enzymes from matched normal skin and scar fibroblasts (a). LOX and LOXL1 expression is significantly increased in scar fibroblasts (p = 0.0317 and p < 0.0001 respectively using Mann–whitney two-tailed test). b Immunohistochemistry showed increased LOX intensity in scar tissue samples when compared to normal skin (n = 11 matched biologically independent human samples of scar and skin). Images of skin (c) and normotrophic scar (d) immunohistochemistry for LOX from an individual patient (n = 11 independent biological pairs were imaged and this shows one matched pair of normal skin and scar from a single individual). Data are shown for each matched pair of normal skin and scar samples. Subsequent statistical analysis was performed using Wilcoxon matched-pairs signed rank test (p = 0.0068). Scale bars 300 microns. *p < 0.05, **p < 0.01, ***p < 0.001 and ****p < 0.0001. Source data are provided as a Source Data file.
