Recombinant IL-37 protein does not modulate the pro-inflammatory response of HSC. (A) Recombinant IL-37 (1 μg/ml) was added every second day along with fresh media to cultured Wt HSC. Supernatants were collected on day 5, 7, and 9 during myofibroblast differentiation and tested for spontaneous IL-6 release. (B) Freshly isolated mHSC from Wt mice were cultured with 1 μg/ml rhIL-37 overnight and subsequently stimulated with LPS (100 ng/ml). mRNA levels were measured by qPCR 6 h after stimulation. Fold changes of mRNA expression were calculated using the ΔΔCt-method normalized to Rpl13a gene expression. Open boxes/bars: PBS, closed boxes/bars: rhIL-37. N = 3.
