Collagen Turnover in Wound Repair--A Macrophage Connection.

In this issue, Rohani et al. (2015) report on the role of macrophage-derived stromelysin-2 (matrix metalloproteinase (MMP)-10) in promoting the turnover of extracellular matrix (ECM) during cutaneous wound repair. They provide evidence that MMP-10 specifically enhances collagenolytic activity of murine MMP-13 produced by M2-like macrophages.

Complement factor H: a biomarker for progression of cutaneous squamous cell carcinoma.

The incidence of cutaneous squamous cell carcinoma (cSCC) is increasing globally. We have studied the expression of complement system components in cSCC. Expression profiling of cSCC cell lines (n=8) and normal human epidermal keratinocytes (n=5) with Affymetrix and quantitative real-time PCR (qPCR) revealed upregulation of complement factor H (CFH) and factor H-like protein-1 (FHL-1) in cSCC cell lines.
