According to this press release, “researchers at the Dresden-based institute, working jointly with the Institute for Biotechnology at the Technical University (TU) of Berlin, engineered a new kind of solution that could render the use of animal-based experiments superfluous in medical research: a multi-organ chip that faithfully replicates complex metabolic processes in the human body with startling accuracy.” (our emphasis)

Using the compact multi-organ chip (comparable in size to a one-euro piece), and those of three separate microcircuits, researchers can study the regeneration of certain kidney cells.
