Let me clarify my position on national stem cell banks, which did not entirely come across accurately in the quotes from me selected for use in the main piece:\n I believe that a National Stem Cell Bank, funded by the government and making high quality cells available to all researchers at reasonable cost (simply the cost of maintenance and transport) would -- contrary to the impression left by the piece -- actually be quite ideal and desirable, and its loss is extremely regrettable and ill-considered (presumably the victim of NIH budget deficiencies). However, if the government fails to meet this obligation, then scientists themselves should fill the gap and provide these important reagents (human embryonic and induced pluripotent stem cell lines) readily and also at simply the cost of maintenance and transport, with no strings attached. This, I believe, is particularly true if the lines were originally derived using federal or state funding and/or if they were published in peer-reviewed and/or high profile journals. Fortunately, some academic entities, like the University of Massachusetts, have stepped into the breach to provide this critical service. They should be commended. They are fulfilling what, I believe, is the obligation of all stem cell researchers to the scientific community.
