Results
Specimen 2A: embryonic day 10.5 (more )
Note: Double labeled: red - Cldn1; green - Pdx1 (assay MGI:6343237).
Structure Level Pattern Image Note
TS17: pancreas primordium Present Regionally restricted 2A Expression of Cldn1 was detected in nearly every Pdx1-positive cell (lateral membrane).
Specimen 2B: embryonic day 10.5 (more )
Note: Double labeled: red - Cldn1; green - Tjp1 (assay MGI:6343238).
Structure Level Pattern Image Note
TS17: pancreas primordium Present Regionally restricted 2B Expression was extensively localized throughout the membrane of the unpolarized pancreatic epithelium, which was also nearly devoid of Tjp1.
Specimen 2C: embryonic day 12.5 (more )
Note: Double labeled: red - Cldn1; green - Tjp1 (assay MGI:6343238).
Structure Level Pattern Image Note
TS20: pancreas epithelium Present Regionally restricted 2C Co-expression with Tjp1 was toward the lumen of the pancreatic epithelium in discrete areas.
Specimen not shown: embryonic day 15.5 (more )
Structure Level Pattern Image Note

Specimen 2D: postnatal day 5 (more )
Note: Double labeled: red - Cldn1; green - Tjp1 (assay MGI:6343238).
Structure Level Pattern Image Note
TS28: pancreatic duct Present Regionally restricted 2D Extensive colocalization was observed with Tjp1 in tight junctions.
Specimen 2E: postnatal day 5 (more )
Note: Double labeled: red - Cldn1; green - Tjp1 (assay MGI:6343238).
Structure Level Pattern Image Note
TS28: pancreatic duct Present Regionally restricted 2E Extensive colocalization was observed with Tjp1 in tight junctions.
TS28: islets of Langerhans Absent 2E
Specimen 2F: postnatal day 5 (more )
