VEGFR1 TK signaling induces the expression of fibrosis-stimulating factors. a TNF-α levels in the lung after BLM treatment. Data are expressed as the mean ± SD (n = 4 mice per group) *p < 0.05 versus WT mice. b-d Expression of S100A4 (b), type I collagen (c), and TGF-β (d) in the lung on day 21 after BLM treatment. Data are expressed as the mean ± SD (n = 4-5 mice per group). *p < 0.05 versus WT mice [11]
