Cloning pioneer urges shift away from embryonic stem cells

Universal Truth at work again. I would have loved to be there in order to watch heads explode and hear the susurus of “Did he say that?” buzzing around the room.

Newer and safer forms of stem cell therapy will likely overtake research into the use of human embryonic stem cells, the scientist whose team cloned Dolly the sheep told his peers at a stem cell conference in La Jolla.

Direct “reprogramming” of adult cells into the type needed for therapy is gradually becoming a reality, Ian Wilmut told an audience of several hundred at the Salk Institute at the annual Stem Cell Meeting on the Mesa. Such a feat was once thought impossible, but in recent years it has been demonstrated in at least two publications, he said.

But it’s been unclear which types of stem cells would prove most useful: the “adult” kind that have a more limited potential to change, or the embryonic kind. The emergence of direct reprogramming provides a promising new option scientists should consider, Wilmut said.

“I’m not quite sure why this hasn’t been pursued more actively,” Wilmut said.

It is difficult to achieve purity in embryonic and induced pluripotent stem cells because they are prone to forming tumors.

Direct reprogramming of cells from one type to the other avoids that danger, because the cells never enter the pluripotent stage to begin with, Wilmut said.

Direct cell reprogramming didn’t exist when California voters approved the stem cell program in 2004 with the passage of Proposition 71. That program was mainly aimed at funding embryonic stem cell research the federal government wouldn’t fund.

However, the program can also fund research with other types of stem cells, such as “adult” cells from umbilical cord blood.

The use and value of embryonic stem cells is an intensely controversial issue.

Many people object to their use because human embryos, which they consider human individuals, are killed to get the cells. Critics also point to the success of adult cells in approved therapies, while no therapy with embryonic stem cells has yet been approved.

Only one treatment with embryonic stem cells is in clinical testing in people. And that company, Geron Corp., recently ended its involvement in what was described as a business decision.

More on the Geron decision to end embryonic stem cell research, here, and on the “Stimulus” funds awarded to Geron and the employees that lost their jobs, anyway, here.

Just one more failed “stimulus” project? This past week, Geron announced they are no longer pursuing their research in embryonic stem cells. They laid off 66 employees.

The US government should never have been in the business of picking and choosing business winners and losers. We certainly shouldn’t be giving money for destructive embryonic stem cell research.

Included as part of the Patient Protection and Affordable Care Act of 2010, the QTDP program provided a tax credit to encourage investments in new therapies to prevent, diagnose, and treat acute and chronic diseases. Companies, such as Geron, that cannot currently use a tax credit were allowed to apply for a cash grant

in lieu of a tax credit.

To be eligible for the program, projects must show reasonable potential to result in new therapies to treat areas of unmet medical need; prevent, detect, or treat chronic or acute disease and conditions; reduce long-term health care costs in the United States; or significantly advance the goal of curing cancer within a 30-year period.

In addition, preference was given to projects that showed the greatest potential to create and sustain (directly or indirectly) high quality, high-paying jobs in the United States, and advance United States competitiveness in the fields of life, biological, and medical sciences.

Projects were selected jointly by the Treasury Department and the Department of Health and Human Services.
