stem cell FAQ hit the limelight in November 1998, after researchers very first reported that they had isolated stem cell FAQ. These cells, isolated from embryos that had been quite a few days old, can theoretically be differentiated into any type of cell during the human body, from blood cells to brain cells to muscle cells. This was big news on the scientific front due to the fact scientists hoped to use these cells to repair damaged cells and tissue in adult humans. Unfortunately this look for breakthrough also made a host of stem cell look for difficulties which are still being debated today. So what's the big fuss about these look for issues? Most on the controversy centers over a fact how the embryonic stem cells come from embryos and scientists have to destroy the embryos to harvest the stem cells. Many 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. You will discover currently many sources of embryos, for instance aborted fetuses and fertility clinics (which have thousands of unwanted frozen embryos). All of these sources are currently undergoing serious scrutiny inside government and various lobbying groups.
