Fig. 6 Py3-FITC can be used to detect TGF-β1-induced collagen type I. HFL-1 cells were treated with TGF-β1 for 0 h (a–c) or 48 h (d–f) and then stained with Py3-FITC (a,d) and collagen type I antibody (b,e), and their merged images are shown (c,f). Collagen type I expression was increased by 48 h of TGF-β1 treatment. The cytoplasmic signal of Py3-FITC was also increased by TGF-β1 and was partially merged with that of collagen type I (c,f). Scale bar in a, 50 μm.
