Table 1 Domain-specific classification of HPD tube formation defects
From: A morphogenetic EphB/EphrinB code controls hepatopancreatic duct formation
HPD domain | Score 1 = mild defect (ductal domains show only one of below defects) | Score 2 = severe defect (ductal domains show more than one of below defects) |
|---|---|---|
Extrahepatic duct (EHD) | Two branches, thinner, enlarged or gap | More than two branches, loops |
Gallbladder (GB) | A bit longer/more inflated, gap, more than one branch attached distally or enlarged cystic duct | Much longerinflated |
Common bile duct (CBD) | Long spike, loop, gap or more inflated | Cystic, loops |
Extrapancreatic duct (EPD) | Long spike, loop, gap or more inflated | Cystic, loops |
