Total cell counts from lung lavage fluid. IL-9 transgene-negative (TG^–) and -positive (TG⁺) mice, 6 weeks of age, were housed with or without doxycycline-supplemented food over a period of 14 days. At three different time points mice were sacrificed, subjected to lung lavage, and total cell numbers assessed. Data are expressed as mean ± SD of counts from four to five animals per group. Significant differences in cell numbers compared with that of transgene-negative and -positive mice that did not receive doxycycline are indicated by an asterisk.
