| In general a distinction is made between totipotent and pluripotent embryonic cells. |
| For the first few divisions, up to at least the 8-cell stage, all the cells of the tiny embryo are totipotent stem cells. |
| The egg, a totipotent cell from which the new organism will develop, thus contains the chromosomal stock which is characteristic for the species. |
| Those cells will be totipotent, will give rise to any tissue. |
| He noted however that in this species, nuclei stay totipotent longer than in Rana. |
| Until the fourth day, each cell is totipotent, and contains all the genetic information of a potential human being. |
