(a,b) Immunostaining for tdTomato, SPC and CC10 on lung sections of BASCs-Tracer mouse. Boxed region is magnified in the below images. Most fields in the lung sections are negative for tdTomato (a), with only very few fields that contain sparse tdTomato+ cells (b). The extremely rare tdTomato+ cell is located in BADJ region, and is expressing SPC and CC10 (arrowhead). (c) The sparse tdTomato+ cell (arrowhead) does not express AT1 cell marker T1a. Scale bars, 100 µm. Each image is representative of 5 individual samples.
