Organs in miniature format

21 February 2019

In vitro processes and animal tests are used to develop new medications and novel therapeutic approaches. However, animal testing raises important ethical concerns. Organ-on-a-chip models promise to be a feasible alternative. In a system the size of a smartphone, organs are connected using artificial circulation.
As an alternative to animal experiments, scientist have relied on the Petri dish to grow or culture cells….The key advantage of organ-on-a-chip models is that they replicate the natural environment found in human cells in specific organs and tissues at microscale. 3D printing technology makes the fabrication of the “organ-on-a-chip” models or chips possible…..The three-dimensional organ-on-a-chip models are a substantial advancement in medical technology and represent the next generation following two-dimensional cell culture.
