Structure Level Pattern Image Note
TS15: trunk mesenchyme Weak Regionally restricted Authors state that expression above background in most posterior mesodermal structures, such as the mesonephric kidney and somite blocks, but weak compared to that of the nervous system.
TS15: mesonephros mesenchyme Weak Authors state that expression above background in most posterior mesodermal structures, such as the mesonephric kidney and somite blocks, but weak compared to that of the nervous system.
TS15: somite Weak Authors state that expression above background in most posterior mesodermal structures, such as the mesonephric kidney and somite blocks, but weak compared to that of the nervous system.
