Where do medical scientists get tissue samples for their research? Say if you’re a neuroscientist studying brain tumors; where would you find enough tumors to study? Great questions. And the answer is that you’d make a withdrawal¹ from a biobank. A biobank is a repository of tissue samples–things like blood, DNA², tumors and other biological samples. Major research institutions like universities and the National Cancer Institute have their own biobanks that collect samples from donors³ and make them available to researchers. One problem, though, is that individual biobanks typically don’t share their resources with everyone. For example, the National Cancer Institute has a network of biobanks. But if you’re not doing cancer research or not affiliated⁴ with the National Cancer Institute, it can be hard to access its biobank. Plus, there are no national or global standards for how biobanks store their material.
