What are the Histological Techniques to Study Type I Alveolar Cells?

Histological examination of Type I alveolar cells typically involves the use of light microscopy and electron microscopy. Light microscopy can reveal the general structure and distribution of these cells within the alveolar walls. However, due to their thinness, electron microscopy is often required to observe the ultrastructural details, such as the thin cytoplasmic extensions and the interactions with the basement membrane and capillary endothelium. Immunohistochemistry can also be employed to identify specific markers expressed by Type I cells, aiding in their differentiation from other cell types.
