Two months ago a research report was published in the scientific journal ‘Nature’ and it caused a bit of a fuss in the embryonic stem cell world.
Embryonic stem (ES) cells are currently being pushed towards the clinic as a possible source of cells for regenerative medicine. But this new report suggested that quite a few of the embryonic stem cells being tested may be carrying genetic variations that could be bad. Bad as in cancer bad.
In this post, I will review the study and discuss what it means for cell transplantation therapy for Parkinson’s disease.
For folks in the stem cell field, the absolute go-to source for all things stem cell related is Prof Paul Knoepfler‘s blog “The Niche“. From the latest scientific research to exciting new stem cell biotech ventures (and even all of the regulatory changes being proposed in congress), Paul’s blog is a daily must read for anyone serious about stem cell research. He has his finger on the pulse and takes the whole field very, very seriously.
For a long time now, Paul has been on a personal crusade. Like many others in the field (including yours truly), he has been expressing concern about the unsavoury practices of the growing direct-to-consumer, stem cell clinic industry. You may have seen him mentioned in the media regarding this topic (such as this article).
The real concern is that while much of the field is still experimental, many stem cell clinics are making grossly unsubstantiated claims to draw in customers. From exaggerated levels of successful outcomes (100% satisfaction rate?) all the way through to talking about clinical trials that simply do not exist. The industry is badly (read: barely) regulated which is ultimately putting patients at risk (one example: three patients were left blind after undergoing an unproven stem cell treatment – click here to read more on this).
While the stem cell research field fully understands and appreciates the desperate desire of the communities affected by various degenerative conditions, there has to be regulations and strict control standards that all practitioners must abide by. And first amongst any proposed standards should be that the therapy has been proven to be effective for a particular condition in independently audited double blind, placebo controlled trials. Until such proof is provided, the sellers of such products are simply preying on the desperation of the people seeking these types of procedures.
