The effect of VEGFR1 TK signaling on lung volume and VEGF concentration in the lung following PNX. (a) There is no difference in the lung volume between TK−/− mice following PNX. Data are means±s.d. for the number of mice (n=6). NS, not significant by Student’s t-tests. (b) The number of alveoli was diminished PNX. Data are means±s.d. for the number of mice (n=6–10). *P<0.05 by Student’s t-tests. (c) The protein level of VEGF in the lung was suppressed in TK−/− mice following PNX. TK−/−, tyrosine kinase knockout. Data are means±s.d. for the number of mice (n=6). *P<0.05 by Student’s t-tests.
