"No path at all"

MIT professor and stem cell researcher James Sherley wrote an article today for Australia's Daily Telegraph on stem cell research. Here's bit of what he had to say:

The idea research on human embryos will yield an amazing medicine chest of new cures for debilitating diseases of children and adults is a myth. Nothing could be further from the truth.....

Some scientists have not revealed the problems that prevent them being used to treat diseases. For example, in terms of fundamental biology, embryonic stem cells are not able to be used to treat adult tissue.

One major barrier to using embryonic stem cells in therapy is tumours could form when they were put into adult tissue....

Despite misinformation to the contrary, adult stem cell research is a viable path to new therapies.

Even calling them an "alternative" to embryonic stem cells misinforms the public. Why? Because embryonic stem cells provide no path at all.
