Totipotent cell

Definition

noun

The cell that is capable of developing into any cell type.


Supplement

In a developing embryo, totipotent stem cells are able to produce every cell type in an embryo, including the extraembryonic tissue.


Compare: unipotent cell, multipotent cell, pluripotent cell.
See also: potency.

"The Totipotential {total potential} Stem Cell is a cell capable of developing into any type of cell in the organism. So far in higher level organisms such as mammals it has only been found that the bone marrow stem cell can become any cell in the organism it came from by physical contact with another cell in the organism such as in scar tissue creation with eventual development into surrounding tissue types.

There are two schools of thought in regards to embryonic stem cells.

One believes that if the right stimulus can be found an embryonic cell can be stimulated to produce different cell types and even different body parts or organs. As to date this has not been successfully accomplished to any level except in lower level amphibian type animals.

The other believes that the potential for the embryo and what the cells will differentiate into is predetermined at the moment of fertilization where it is set on it's course of development.

As to date there has been nothing other than amphibian cell stimulation causing sporadic uncontrolled and odd additional body part developments in developing amphibians showing more a disruption in the development process rather than a stimulation for anything less chaotic that agrees with the first hypothesis presented that disagrees to some lesser degree with the second hypothesis presented."

Re: Totipotent Stem Cell From Molecular Components

I am not saying # of protein x = # of protein y(In fact this is almost never the case). Rather I am saying that for a particular protein in my stem cell at least, the amount of that particular protein is the average of the gene expression in # of strands of mRNA * 100. I am getting the protein this ...

Re: Totipotent Stem Cell From Molecular Components

A1: good luck, even Venter haven't managed that yet. A3: and how will you get the protein? Are you really sure that the stemm cells contain all protein in the same amount? A4: amplicon is the result of PCR. You need some template though, in your case probably the DNA.

Totipotent Stem Cell From Molecular Components

Q1 I am wanting to make an animal cell from DNA, RNA, Protein, and Fatty Acids as well as Glucose and other sugars. I am wondering. Should I start with the cell membrane or the nucleus and nucleolus(both are very important)? Q2 The pace of ...

Hi cathbr, 1) Yes they are Somatic cells, the definition of a somatic cell is - Any cell in a multicellular organism ... type to proliferate. With regards to the potency of the cells, zygotic cells are totipotent - meaning they can differentiate into any of the somatic cells of the organism. ...
