Could a whole set of artificial organism-cloning process only be operated on the somatic nuclear donor ,which means for example ,can we extract the somatic nuclear from animal "A" and put it into the egg cell plasma also from animal "A" then implant it into the animal"A"'s uterus to clone "A" ?

No, this would not be possible. Single-cell reprogramming would enable you to reset the potency status of that cell up, yielding an embryonic stem cell (ESC). However, ESC do not have the ability to generate extra-embryonic structures (e.g. placenta), which are known to be required for providing oxygen and nutrients to the embryo, amongst other relevant functions.
Theoretically, it could be possible to replicate the embryological environment, and I think this is the second part of your statement. Nevertheless, in practice this is not possible... the amount of signals and parameters that one would need to control simultaneously is far too extensive.
I don't quite see the point of having an enucleated egg and performing somatic cell transfer, when you're not really interested in implantation in utero. Somatic cell reprogramming would be sufficient (see iPSC)
we use egg cell because it has tendency to cleave and provide nourishment to the developing embryo while this can not be obtain by any other somatic cell. if in case of mammals the egg is also capable to adjust in the placenta and grow and obtain required objectives as nourishment and exchange of materials with the mother body.
