Fig 11. TGF-β+ cells in peribronchovascular areas.

Fig 11

The numbers of TGF-β+ cells in peribronchovascular areas obtained for the Control groups after 1 (n = 4), 3 (n = 4), and 6 (n = 4) months and Smoke groups after 1 (n = 6), 3 (n = 5), and 6 (n = 6) months are presented as the means ± SDs. (A) Significant differences were found after 1 (*P = 0.0472, t-test), 3 (*P = 0.0024, t-test), and 6 (*P = 0.0140, t-test) months. (B) Representative photomicrographs of TGF-β+ cells in peribronchovascular areas are shown at 200× magnification, and images at 1000× magnification are shown in each insert.
