Most scientists and researchers believe that embryonic stem cells have great potential in treating diseases such as multiple sclerosis, Parkinson's disease, cancer, Alzheimer's disease, various heart diseases, genetic disorders etc. Research on these cells will help scientists in understanding the development of various diseases and this may also provide a cure for such diseases. Current research has indicated that embryonic stem cells have tremendous potential in saving human lives. The con of this type of research is that one would have to destroy a few day old embryo to extract cells and many people believe that this is morally incorrect. Life begins as soon as fertilization occurs and destroying this life in order to cure other human beings is not correct. Embryonic stem cells involve various steps where decisions are made by scientists and since the process involves a living embryo this is not morally correct. Also, it is widely believed that proper focus has not been given to adult stem cells. Adult stem cells can be isolated from a grown up living person and one does not need to harm the developing embryo. These cells have


Embryo is the initial stage of development of a multicellular organism.Each embryo starts development as zygote and development of a zygote into a multicellular embryo goes into a series of identifiable stages,mostly divided into cleavage , blastula ,gastrulation and organogenesis.Cleavage is the duration of fast Mitotic cell division that results after fertilization.
Pros of research on embryonic stem cells are that they have large potential in curing various diseases and saving human lives.Cons of this kind of research is that it is considered morally wrong because destruction of few day old embryo cells for extraction of cells indicates killing the life for curing other humans.So its believed that it's better that extraction of cells from adult stem cells should be focussed instead of developing living embryo cells.
