the discovery of human stem cells (precursor
cells that can give rise to multiple tissue types), including embryonic stem
(ES) cells, embryonic germ (EG) cells, and adult stem cells. Recently,
techniques have been developed for the in vitro

both properties are the common result.

34. Stem Cell Topic: Ethics Influencing Science?
Is it because totipotent cells have a genetic
potential lacking in pluripotent cells? No. What distinguishes them is that
totipotent cells have access to a placenta making them available for
implantation; whereas pluripotent stem cells lack

Initially and naively, we could breathe a sigh of relief. If
