From: Spatial and temporal expression of surfactant proteins in hyperoxia-induced neonatal rat lung injury
Immunohistochemical staining of Clara cell secretory protein on formaldehyde fixed paraffin sections of rat lungs during normal postnatal development at birth (A), day 6 (C), day 10 (E) and 6 months (B) and after exposure to hyperoxia on day 6 (D) and 10 (F) at a 200-fold magnification. a = alveolus, br = bronchus, bv = blood vessel, s = saccule, tb = terminal bronchus.
