Results
Specimen 1D: embryonic day 11.5 (more )
Note: Vibratome section.
Structure Level Pattern Image Note
TS19: brachial plexus Present Regionally restricted 1D Expression in axons innervating dorsal axial musculature.
TS19: future spinal cord Present 1D Expression along entire length of spinal cord.

Specimen 1E: embryonic day 11.5; Epha4tm1Pch/Epha4tm1Pch (more )
Note: Vibratome section.
Structure Level Pattern Image Note
TS19: brachial plexus Absent 1E

Specimen 5B: embryonic day 11.5 (more )
Note: Vibratome section.
Structure Level Pattern Image Note
TS19: segmental spinal nerve Strong Regionally restricted 5B
TS19: peripheral nervous system Strong Regionally restricted 5B Axons entering the dorsal compartment of the limb bud were still strongly labelled, whereas axons projecting ventrally were only weakly positive.
TS19: future leg mesenchyme Strong Regionally restricted 5B Expression is in the proximal part of the dorsal limb bud.
