Figure 2From: Truncated recombinant human SP-D attenuates emphysema and type II cell changes in SP-D deficient miceLow power electron micrographs from lungs of (A) group D0 and (B) group D3. Figure A demonstrates enlarged type II cells filled with abundant lamellar bodies and some alveolar macrophages. Compared to the untreated lung, B shows numerous type II cells without any obvious differences in size and lamellar body content per cell, emphasizing the need of proper design-based stereological investigation.Back to article page
