Other authors have proposed that such teratomas may originate from totipotential embryonic rests in the left genital ridge.
-
That statement is also misleading since ASCs are limited because they are multipotent but not totipotent - they can form some, but by no means all of the different kinds of cells in the body.

-
They have not usually been described as totipotent because, the inner cell mass having already differentiated from trophoblast, the cells of the inner cell mass were believed to be no longer able to give rise to the cells of the trophoblast.

But this whole idea that there are three different types of cells out there -- there are what as known as totipotent cells which come from the very earliest stages of an embryo -- they can develop into anything, including another human being.

What he showed next were a series of experiments in which they pushed cultured, totipotent mouse embryonic stem cells to desired neural fates using the various factors he had identified as significant in vivo.
-
embryonic stem cells are totipotent
-
While each somatic stem cell of the adult organism is committed to a certain line of differentiation, the early embryo contains stem cells that are totipotent, i.e. they give rise to all cell types in the developing organism.

These are so-called totipotent cells, meaning that they have ability to differentiate, or diversify, into any type of cell.
