In the last few decades, several technologies have been developed using human cells or stem cells. Another popular technology is the “organ-on-a-chip”: they are AA-battery-sized chips lined with human cells connected to microchannels, to mimic blood flow inside the body. Several innovations in the last decade now allow a 3D bioprinter to ‘print’ biological tissues using human cells and fluids as ‘bio-ink’. Such technologies, researchers say, are bringing us closer to recreating a human tissue or organ system in the laboratory. In the same month, South Korea introduced a Bill called ‘Vitalization of Development, Dissemination, and Use of Alternatives to Animal Testing Methods’.
