totipotent

(tō-tĭp′ō-tĕnt) [L. totus, all, + potentia, power]
In embryology, the ability of a cell or group of cells to produce all of the tissues required for development (i.e., the embryonic membranes, the embryo, and finally the fetus).

They can be classified as totipotent cells, naive pluripotent stem cells, primed pluripotent cells, and tissue-specific multipotent stem cells.
The development of the intestinal mucosa occurs by cytological processes where totipotent cells in constant renewal and proliferation differentiate up and migrate from the crypt and other regions along the villi and are extruded at the apex of the villi, causing an increase in villus volume, depth of crypts and enzymatic activity of the mucosa (Uni, Platin, & Sklan, 1998).
While the exact origin of the totipotent stemlike cells responsible for WBR remains unknown, it has been reported that even though they will develop a regeneration niche within the vascular system, they are not part of the circulating blood cells (hemocytes) in uninjured colonies but rather appear to migrate from the vascular lining into the vascular system after injury (Rinkevich et al., 2010).
Two basic types of stem cells are distinguished: totipotent embryonal cells, which can differentiate in any type of cell; and somatic cells of limited differentiation potential [2].
