Stem Cells Creted From Pig Cells In China

pigScince Daily had reported via EurekaAlert a research published in journal of molecular cell biology that scientists have managed to induce cells from pigs to transform into pluripotent stem cells. Pluripotent cells aare cells like embryonic stem cells, are capable of developing into any type of cell in the body.

It is a breakthrough. It is the first time in the world that this has been achieved using somatic cells (cells that are not sperm or egg cells) from any animal with hooves or ungulates. [Read more...]

Controversis Around Embryonic Stem Cell Research – Are Adult Cells An option

June 2, 2009 By Leave a Comment

Adult stem cell is cited as possible and viable alternative when a ban on embryonic stem cell is asked.  It is true that re adult stem cells have the potential and area morally less problematic alternative.

But  there are a  lot of possible  problems. First is that human adult stem cells are rare, of few types  and difficult to isolate.

Most of these are difficult to grow in culture. Much of the work on human adult cells is of hematopoietic stem cells an results of this work can not be generalized to other types.

However, adult stem cells if they can be harnesses have potential to produce  histocompatible transplant which would not trigger immunological responses.

Controversies Surrounding Embryonic Stem Cell Research

Stem cells are surrounded by controversies

Embryonic stem cells have been center of controversies. The issue s involved are legal, ethical, religious and moral. As it involves area surrounding human reproduction, it is natural to get much attention and opinion from all authorities and fields just like contraception, abortion, and in vitro fertilization.

Actually it is the way society takes this issue of human life and the moral and legal status of the human embryo.

Greatest objection to embryonic stem cell research comes from the fact that research deprives a human embryo of any further potential to develop into a complete human being.

It amounts to killing of  life  of  a human being and killing humans for treating humans is not justified. But even society does not universally agrees when an embryo can be called live.

Let us look at this [Read more...]
