Donald Ingber and his team, having seen the successful results of the lung-on-a-chip, have developed other types of “organs-on-a-chip” such as a human gut-on-a-chip, kidney-on-a-chip, and bone marrow-on-a-chip. And they’re looking into mimicking even more organs with the hope of linking them all together one day and creating a human-on-a-chip. These incredible and revolutionary devices represent new and more powerful ways to accelerate the introduction of new drugs to market, provide an alternative to animal studies, and lower research costs. Dr. Ingber discusses the benefits of organs-on-a-chip and the hurdles that are still before him and his team.
