Elastin deposition is not dependent on PDGF-A expression from AEC2s. A, B: postnatal day 7 (P7) lung vibratome sections (100 µm) stained for Elastin (white). C: volume of Elastin in control and knockout P7 lungs. D: relative levels of mRNA expression of Eln normalized to 18s rRNA endogenous control. E, F: adult lung vibratome sections (100 µm) stained for Elastin (white). G: volume of Elastin in control and knockout adult lungs. H: relative levels of mRNA expression of Eln normalized to 18s rRNA endogenous control. Control mice n = 5–6; knockout mice n = 5–6. Graphs are represented as means ± SE. Statistical analysis was done using Student’s two-tailed unpaired t test. n.s. Nonsignificant. Scale bars: 50 µm.
