human embryonic stem cells hit the limelight in November 1998, after researchers very first reported that they had isolated stem cell therapy. These cells, isolated from embryos that were many days old, can theoretically be differentiated into any type of cell inside the human body, from blood cells to brain cells to muscle cells. This was large news on the scientific front mainly because scientists hoped to use these cells to repair damaged cells and tissue in adult humans. Unfortunately this look for breakthrough also created a host of stem cell look for difficulties which are still being debated today. So what is the large fuss about these search issues? Most in the controversy centers on the truth that the new stem cell research 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'll find currently numerous sources of embryos, such as aborted fetuses and fertility clinics (which have thousands of unwanted frozen embryos). All of these sources are currently undergoing serious scrutiny from the federal government and a number of lobbying groups.
