From: Characteristics of pulmonary microvascular structure in postnatal yaks

The microstructure of yak alveoli at different developmental stages observed using HE staining and Masson’s staining. (A) Representative sections from 1-day old animals to adults (scale bar represents 10 µm, 1000×). (B) Graph representing the mean area of individuals pulmonary alveoli (C) Graph representing the mean interalveolar septum thickness. Values represent the mean ± SD (n = 3). Different letters (a, b, c, and d) indicate significant differences (P < 0.05).
