Stem Cell Research: Controversies Abound
Unique among structures in the body, embryonic stem cells can be converted to almost any type of cell, carrying the promise of a cure for diabetes, Parkinson's disease and shattered spines, among other conditions. A considerable number of Americans, however, think that conducting research with stem cells derived from human embryos is immoral.
In early 2008, a new twist was added to the controversy when scientists reported having found a way to safely remove cells without destroying embryos. This discovery may let the disputed technique become more widely accepted within the medical research field. Updated March 2010
