Stem Cells Research: What Are They?
There has been a debate about stem cell research since 1998 when the
research teams of James A. Thomson of the University of Wisconsin and
John D. Gearhart of Johns Hopkins University School of Medicine
announced the isolation of human stem cells (Farrell). But before anyone
should take a side, one must know what a stem cel...
