Summary
-
1.
The intricacy of regeneration depends largely on the behaviour of cells during early hours of contact.
-
2.
Cellular contact is a necessary prerequisite to bring about the phenomenon of regeneration.
-
3.
Cells dedifferentiate and attain a generalized state before regeneration.
-
4.
Certain unipotent cells can only redifferentiate into original fate e.g., pinacocytes, scleroblasts, choanocytes.
-
5.
Other types of cells completely lose their original characteristics and become totipotent i.e. redifferentiate into other types of cells. These are called pluripotent cells e.g. amoeboid cells.
-
6.
Definite orientation of cells are observed from the beginning of cell aggregation. Archeocytes remain in the periphery and other cells in the middle of the mass.
-
7.
Redifferentiation begins from 4–6 hours stage of reaggregation.
