Corrections.(1) In our December issue, under Vatican News in Brief, page 25, we referred to embryonic stem cells Embryonic stem cells (ES cells) are stem cells derived from the inner cell mass of an early stage embryo known as a blastocyst. Human embryos reach the blastocyst stage 4-5 days post fertilization, at which time they consist of 50-150 cells. ES cells are pluripotent. as the earliest stage of human beings. This is incorrect. Embryos are the earliest stage of life. Stem cells stem cells, unspecialized human or animal cells that can produce mature specialized body cells and at the same time replicate themselves. Embryonic stem cells are derived from a blastocyst (the blastula typical of placental mammals; see embryo), which is very young are the master cells found in every tissue in the human body which continue to reproduce those tissues throughout one's life. Some modern scientists seeking to remove embryonic stem cells, destroy the embryo embryo (ĕm`brēō), name for the developing young of an animal or plant. In its widest definition, the embryo is the young from the moment of fertilization until it has become structurally complete and able to survive as a separate organism. and therefore kill the earliest form of human life.
