Note: Specimens were fixed in absolute alcohol.
Structure Level Pattern Image Note
TS22: main bronchus mesenchyme Present Regionally restricted 1D Expression is detected in one or two layers of mesenchymal cells surrounding the main bronchi; intensity of expression increased compared to E12.5.
TS22: lobar bronchus mesenchyme Present Regionally restricted 1D Expression extended into the proximal portions of the second order bronchi and walls of the main blood vessels.
TS22: main bronchus vascular element Present Regionally restricted 1D Expression extended into the proximal portions of the second order bronchi and walls of the main blood vessels.
