β-galactosidase expression activated by B6.EIIa-cre in adult lung
 A) Adult (8 weeks old) female lung at 10X magnification. |
 B) Adult (8 weeks old) male lung at 10X magnification. |
 C) The same section as A, at 40X magnification. β-gal expression is strong in all lung tissue. |
 D) The same section as B, at 20X magnification. β-gal expression is strong some lung tissue. |
| Note: The difference between β-gal expression for the male and female samples are just initial observations. No quantification was conducted to determine if a true sex-based difference is present with the B6.EIIa-cre line. Compare to P7 lung. | |
