No, no, not adult human stem cells for animals, but homologous adult stem cells for the animal itself. So says this article, about an elderly dog with arthritis in his leg.
According to the website of the firm that extracted the multipotent 'stem cells' from the fats tissue of the dog cured, adipose-derived 'regenerative cells' are more readily available than those taken from the bone marrow, and seem to be effective in repairing muscle and cartilage damages in those animals treated. Also, it seems like the application of the treatment is fairly straightforward: simple injection of the stem cells harvested, directly to the site of injury.
So one wonders again, why is there so much emphasis given to embryonic stem cells research when we could focus our attention to what has been proven to work?
