Totipotency is not merely a state of the cell's nucleus; it also requires a very specific type of cellular cytoplasm that is a critical component of totipotency. At this time, the only known totipotent cytoplasm is produced by an oocyte and contributed to the embryo at fertilization.

Totipotency is the genetic potential of a plant cell to produce the entire plant. In other words, totipotency is the cell characteristic in which the potential for forming all the cell types in the adult organism is retained.

In the spectrum of cell potency, totipotency represents the cell with the greatest differentiation potential, being able to differentiate into any embryonic cell, as well as any extraembryonic tissue cell. In contrast, pluripotent cells can only differentiate into embryonic cells.

2022年6月16日 · About totipotent cells, totipotency, difference between totipotent, pluripotent and multipotent cells, therapeutic use and examples of totipotent cells.

The term totipotency is derived from two words, totus ( Latin) means entire and potent means to be able or have power. Thus, totipotency is the ability of a single cell to divide and produce all the differentiated cells of an organism.

Totipotency represents the highest differentiation potential and allows cells to form both embryo and extra-embryonic structures. One example of a totipotent cell is a zygote, which is formed after a sperm fertilizes an egg.

2014年4月15日 · In this context, clarifying precisely what is meant by "totipotency" and how it is experimentally determined will both avoid unnecessary controversy and potentially reduce inappropriate barriers to research.

A review article summarizing recent findings related to totipotency in mammals, encompassing topics such as the epigenome and gene regulation in early embryos, in vitro totipotent-like cells, and somatic nuclear transfer.
