Changes in the expression levels of elastic fibres in yak lungs at different growth stages

摘要

Basic structure and quantitative measurement of alveolar tissue in yaks at different growth stages. (a) HE staining and elastic fibre staining of the alveolar tissues of plateau yaks at four ages: 1 day old, 30 days old, 180 days old and adult. The number of alveoli per unit area (b), average single alveolar area (c), and percentage of elastic fibres (d) in the lung parenchyma of yaks. Note: TS: translucent structure
