future midbrain |
|
detected |
| regional | PN-1 transcripts were detected in the ventral neural tube at the met-/mesencephalon junction. PN-1 mRNA was also observed in the ventral part of the mes- and diencephalon |
diencephalon |
|
detected |
| regional | PN-1 mRNA was also observed in the ventral part of the mes- and diencephalon |
tail |
|
detected |
| regional | PN-1 mRNA was also observed in the ventral ectodermal ridge of the tail |
telencephalic vesicle |
|
not detected |
| | Staining in the telencephalic vesicles was considered as an artefact since it could also be observed in control embryos either hybridized with a sense mouse PN-1 riboprobe or without a riboprobe |
branchial arch |
|
detected |
| regional | PN-1 mRNA was also in the ectoderm of branchial arches. |
otocyst |
|
detected |
| regional | PN-1 mRNA was observed at the surface of the otic vesicle |
