An interesting paper in PLos Medicine looks at the best next steps for regenerative medicine. It's intended to focus on the "developing world" (or, more accurately, the "world sabotaged by corruption and willful economic ignorance") - but the recommendations come across as common sense for the field as a whole, no matter what region you might live in. A panel of experts put forward their view of "the ten most promising applications of regenerative medicine for improving health in developing countries ... Top-ranked application: Novel methods of insulin replacement and pancreatic islet cell regeneration for diabetes. ... Second-ranked application: Autologous cells for the regeneration of heart muscle after myocardial infarction and cardiomyopathies. ... Third-ranked application: Immune system enhancement by engineered immune cells and novel vaccination strategies for infectious disease."
