These totipotent cells
can differentiate into tissue components representing derivatives of mesoderm, ectoderm and endoderm.
Another form of ANT, known as "oocyte-assisted reprogramming" (ANT-OAR), involves the activation of genes that are expressed in pluripotent cells, but not in totipotent cells
. In standard SCNT, factors in the egg cytoplasm reset the nucleus of the body cell to the totipotent state of a naturally produced zygote.
In his appendix, Michael Gazzaniga describes the distinction between pluripotent and totipotent cells
Stem Cells Based on Their Cell Potency and Differentiation Classified into Unipotent Cells, Multipotent Cells, Pluripotent Cells and Totipotent Cells
In nematode galls, independent on the host plant or organ, the nutritive tissues may have promeristematic and totipotent cells
or giant polynucleated cells (Fig.
In a culture of embryonic stem (ES) cells, a small population (around one percent) spontaneously turns into cells that are similar to the totipotent cells
of the 2-cell stage embryo.
During embryogenesis, totipotent cells
such as primordial germ cells and hematopoietic stem cells migrate from the yolk sac through this region to populate target tissues in the embryo and fetus .
They can be classified as totipotent cells
, naive pluripotent stem cells, primed pluripotent cells, and tissue-specific multipotent stem cells.
Three possibilities may be considered: (1) migration of cells from the maxillary sinuses or from the nasal cavity, (2) metaplasia of the stratified squamous epithelium, or (3) differentiation from totipotent cells
present in the jawbones .
However, the BIA revealed however, quite alarming fat mass values, probably correlated to a greater differentiation of totipotent cells
into adipocytes, which occurs when excessive food intake happens during the growth phase.
It also increases the count of totipotent cells
positive for the CD133 antigen.
