Direct Detection
Results
Specimen 4H: embryonic day 11.5; Mesp2tm4Ysa/Mesp2+ (more )
Structure Level Pattern Image Note
TS19: tail paraxial mesenchyme Present Regionally restricted 4H Expression is present in the rostral caudal region of each somite. Expression persists in more rostral somites due to the stability of the enzyme.

Specimen 4K: embryonic day 11.5; Mesp2tm4Ysa/Mesp2tm4Ysa (more )
Structure Level Pattern Image Note
TS19: tail paraxial mesenchyme Present Uniform 4K Expression is present throughout the somites; it is no longer limited to the rostral caudal region. Expression persists in more rostral somites due to the stability of the enzyme.
