Animal Cloning
We do not know how to de-differentiate animal tissues
nor to re-differentiate them for creation of new animals
un-differentiated animal cells are called
stem cells
. . -presumedly, de-differentiated animal
cells would also be stem cells
. . -and re-differentiation could produce
transplantable organs
. . -which would be genetically identical
to the cell donor
. . . [and transplant recipient]
Hypothesis: if diploid DNA were injected into enucleated egg (or zygote)
the resulting cell would be a 'zygote' genetically identical to the donor
Dolly, the sheep
cloning of agriculturally important animals
. . -such as race horses?
. . -such as mules?
. . -such as ...?
fully 'de-differentiated' cell [zygote] will
're-differentiate' by development
effectively producing transplantable organs
. . -which would be genetically identical
to the cell donor
. . . [and transplant recipient]
