A partipotential system cannot carry out all needed critical subsystem processes, in direct contrast to a totipotential system that is fully self-sufficient.
With both lateral and downward dispersal, the solution to the problem may lie within the larger system, so that it remains totipotential. Other times however the system proves to be partipotential.
* Embryonic stem-cell (ESC) therapy is based on the use of totipotential stem cells derived from embryonic tissues and is the source of much of the controversy in the United States.
They are believed to originate from early gestation from totipotential cells of Hansen's node, a remnant of these primitive streaks in the coccygeal origin (2).
During embryogenesis, germ cells migrate in a path from the entoderm of the yolk sac to the gonads via the dorsal mesentery of the hindgut, and rests of totipotential cells may theoretically become sequestered along this path.
These tumors can originate in stem (totipotential) cells in a manner somewhat analogous to the formation of teratomas.
We believe that the origin of the GP is best explained on the basis of the totipotential nature of adult stem cells that are capable of exhibiting differentiation along diverse cellular lineages.
Therefore, the tumor in the present case is thought to have derived from a single totipotential stem cell and seems to support a metaplastic growth process.
As previously mentioned, the histogenesis of carcinosarcomas remains uncertain and there is no agreement on the nomenclature.[1,12,14-17] Some investigators feel that these tumors develop as a result of the capability of the undifferentiated, totipotential neoplastic cell to undergo multiple pathways of terminal differentiation into histologically recognizable mesenchymal and epithelial elements.
