[http://www.victoriaadvocate.com/weblogs/jonathanjenn49/post/ stem cell guide] hit the limelight in November 1998, as soon as researchers first reported that they had isolated [http://AftonPaker14670.newsvine.com/_news/2012/05/13/11687850-one-of-the-most-left-out-solution-for-stem-cell-research stem cell research]. These cells, isolated from embryos that were many days old, can theoretically be differentiated into any sort of cell within the human body, from blood cells to brain cells to muscle cells. This was big news over a scientific front simply because scientists hoped to use these cells to repair damaged cells and tissue in adult humans. Unfortunately this research breakthrough also created a host of stem cell research problems which are even now getting debated today. So what is the big fuss about these search issues? Most of the controversy centers over a simple fact how the [http://quintennolan25.insanejournal.com/380.html stem cell therapy guide] come from embryos and scientists have to destroy the embryos to harvest the stem cells. Quite a few pro-life and religious groups argue that an embryo represents a human life and that embryonic stem cell work is equivalent to murdering human lives. There are currently many sources of embryos, for example aborted fetuses and fertility clinics (which have thousands of unwanted frozen embryos). All of these sources are currently undergoing serious scrutiny inside the federal government and a number of lobbying groups.
