Results
Specimen 5A: embryonic day 12.5 (more )
Note: Double labeled: green - Icam1; red - laminin.
Structure Level Pattern Image Note
TS20: lung mesenchyme Weak Regionally restricted 5A Expression is in the extra bronchial mesenchyme.

Specimen 5B: embryonic day 16.5 (more )
Note: Double labeled: green - Icam1; red - laminin.
Structure Level Pattern Image Note
TS24: bronchiole epithelium Present Regionally restricted 5B Expression is in forming airways on epithelial cells just distal to the regions of dichotomous branching and is absent in the more proximal bronchiolal or bornochial epithelium.
TS24: lobar bronchus epithelium Present Regionally restricted 5B Expression is in forming airways on epithelial cells just distal to the regions of dichotomous branching and is absent in the more proximal bronchiolal or bornochial epithelium.
TS24: lung epithelium Present Regionally restricted 5B Expression is in forming airways on epithelial cells just distal to the regions of dichotomous branching and is absent in the more proximal bronchiolal or bornochial epithelium.
