Determination of the volumes of the different lung lobes of mice before (control) and 21 days after left-sided pneumonectomy (21d PNX)
As the four right lobes do not equally increase in volume during compensatory lung growth, their relative size changes
Mass specific volumes means lung volume per gram of body weight
Data are presented as mean±sem (control n=20; 21d PNX n=8)
Statistics were done applying paired t-test for control and 21days post PNX groups (cm3·g−1)
