Stem cell cures horizon blows out
Could take a century, says researcher
Despite President Obama’s thumbs-up to embryonic stem cell (ESC) research last
week, the day when stem-cell cures become available is receding further and
further over the horizon. A few years ago, some scientists were rashly promising
5 to 10 years, which then became 20 years, and then 25 years. Now, one of the
leading American supporters of ESC research, Harvard researcher George C. Daley,
says that it could take "the better part of this century". "It took much of the
20th century to figure out how to deliver chemicals as drugs," Daley told AP.
"We should be humble and appreciate it may take us the better part of this
century to truly harness the power of cells as medicines." ~ AP,
