Totipotentiality is found only when sperm fuses with ovum to create a zygote.
When hlaberlandt, (1902) attempted the first plant tissue culture, his intention was to develop a more versatile tool to explore morphogenesis and to demonstrate totipotentiality of plant cells.
Grifo stressed that the technique is different from cloning in that cloning involves the transfer of an adult cell without sexual reproduction, and the nucleus of that cell needs to be reprogrammed to reinitiate totipotentiality.
4) One could theoretically harvest the cells of the morula prior to blastocyst formation; each of these thirty-two cells is capable of producing both placental and embryonic tissue and therefore has totipotentiality while the inner cell mass of a later embryo has pluripotentiality.
12] Since all somatic cells contain 46 chromosomes, in theory, each cell has totipotentiality.
Because of the totipotentiality of the cells during this early process of development, they are able to compensate for an error in another cell or to provide DNA for a missing cell, as he correctly notes.
As stated previously, during the first fourteen days of the developmental process, the totipotentiality of the cells of the inner mass of the very early embryo can split spontaneously to form identical twins or be cleaved chemically at an earlier stage to form what are referred to as blastomeres.
Those difficulties, to which I believe all other related difficulties can be reduced,(7) are the following:(8) the problem of the hydatidiform mole, the zygote's requirement for maternal cytoplasm, and the problem of totipotentiality (including the issue of twinning).
Now I address three problems for the suggestions I am making: (1) the hydatidiform mole, (2) the zygote's requirement for maternal cytoplasm, (3) and the problem of totipotentiality (including twinning).
Seemingly dependent upon a notion of each blastomere's radical indeterminacy and totipotentiality, Bedate and Cefalo think that cell differentiation into cells that have functional, and not material or positional, difference cannot be accounted for unless we look outside of the zygote for maternal factors.
53) A good example is the judgment whether individuality is or is not compatible with the totipotentiality of aggregate cells.
11) Totipotentiality may last considerably longer, up to two or three weeks.
