For most in the scientific community, the debate was never truly about whether adult stem cells or embryonic stem cells would be the most useful therapeutically or whether we could obtain embryonic - like stem cells without destroying embryos.

It is in this sense» and only this sense» that the stem - cell wars are over: The central cause of battle, the destruction of human embryos, is no longer necessary or even most useful.

In fact, when the 2007 paper came out, the commentaries in most scientific publications were quick to point out that, despite the success with adult cells, there was still a need to continue embryo - destructive research and that it would be critical to the advancement of science that research on embryonic stem cells continuIn fact, when the 2007 paper came out, the commentaries in most scientific publications were quick to point out that, despite the success with adult cells, there was still a need to continue embryo - destructive research and that it would be critical to the advancement of science that research on embryonic stem cells continuin most scientific publications were quick to point out that, despite the success with adult cells, there was still a need to continue embryo - destructive research and that it would be critical to the advancement of science that research on embryonic stem cells continue.

Fetal stem cells, which may turn out to be useful for treating conditions like Parkinson's, need to be cloned — that is, researchers need to take a cell from a body, put it in an embryo, and grow that embryo to a certain small size before harvesting the stem cells.

Under Child's theory there is complete continuity from the reaction of the cell with its environment, which constitutes the primary metabolic gradient, and from the later reactions, by which the pattern of the developing embryo is laid down in accordance with the changing gradient pattern, to the intellectual processes by which the adult organism adjusts its relations to the outside world.
