Here we have a look at the mess people have made of what should have been a good, solid decade of unrelenting progress in the foundation of regenerative medicine, via EMBO reports: "it is still unclear which human stem cells -whether embryonic [ESCs] or adult [ASCs] - will be developed and for which conditions. Given this, the focus of the NIH in the USA, and research organizations in other countries, should be on developing human research capacity in both ASCs and ESCs. Each type of research will take time to mature. The ethical debate will need to produce acceptable policy and regulatory compromises so that the regulatory burden can be reduced and investors' risk aversion can be overcome. If these things happen, the major remaining barrier to realizing the medical benefits of stem-cell research might be the lack of skilled scientists in the field."
