CO OZNACZA SŁOWO TOTIPOTENT
Siła komórkowa
Siła komórkowa jest zdolnością do rozróżnienia komórek w inne typy komórek. Im więcej komórek komórkowych może się wyróżniać, tym większa jest jego moc. Potencjał jest również opisany jako potencjał aktywacji genów w komórce, która podobnie jak kontinuum rozpoczyna się od totipotencji w celu wyznaczenia komórki o największym potencjale różnicowania, pluripotencji, multipotencji, oligopotencji, a wreszcie uniotencji. Potencjał pochodzi od łacińskiego określenia "potens", co oznacza "posiadanie władzy". Pluripotencjalne, embrionalne komórki macierzyste pochodzą z komórek macierzystych wewnątrz blastocysty. Te komórki macierzyste mogą stać się dowolną tkanką w ciele, z wyłączeniem łożyska. Tylko komórki moruli są totipotencjalne, mogą stać się wszystkimi tkankami i łożysko.

Stem Cells: From Hydra to Man
In the past, the neoblasts were called “totipotent” stem cells, but recently it has
become clear that we must instead call them “pluripotent” stem cells (National
Institutes of Health 2001). In the classical definition, cells that can give rise to all

They are all derived from a totipotent zygote generated after fertilization of an
oocyte. William Harvey in 1651 was the first to propose that "everything comes
from an egg," which also encapsulated the concept of epigenesis or the gradual ...

Stem Cells and Tissue Homeostasis
The idea that the fertilised egg is a stem cell has probably arisen because of
confusion between the concept of a totipotent cell and a stem cell. We would
define a totipotent cell as one which retains the full range of differentiative
capacities of ...
