H:A
tubule forms in the cranial part of the cord and then
|
|
|
the epithelial
cells proliferate and migrate caudally.
|
|
|
Exp:
Coherent growth of an epithelial cord; very high
|
|
|
replication rate
in these cells.
|
|
|
| • |
H: A wave
of Mesenchymal to Epithelial Conversion.
|
|
|
1.Cells could
incorporate along the length of the cord as
|
|
they convert into
epithelia.
|
|
|
Exp:
the tubule to be a mosaic of cells.
|
|
|
2.Cord is formed and then converts in
situ in a two step
|
|
|
process.
|
|
|
Exp:
We could dissociate cord formation and
|
|
|
epithelialization.
