University of Queensland researchers announced on December 13, 2013 that they have grown a kidney using stem cells. They say the breakthrough paves the way for improved treatments for patients with kidney disease. It’s also meaningful to the future of the wider field of bioengineering organs. Professor Melissa Little from UQ’s Institute for Molecular Bioscience led the study. Her team designed a protocol that prompts stem cells to form all the required cell types to self-organize into a mini-kidney in a dish.
Professor Little said in a press release:
During self-organization, different types of cells arrange themselves with respect to each other to create the complex structures that exist within an organ, in this case, the kidney.
The fact that such stem cell populations can undergo self-organization in the laboratory bodes well for the future of tissue bioengineering to replace damaged and diseased organs and tissues.
It may also act as a powerful tool to identify drug candidates that may be harmful to the kidney before these reach clinical trial.
As always, these scientists cautioned that this is just a first step, but it is an exciting step.
Bottom line: Researchers at the the University of Queensland’s Institute for Molecular Bioscience designed a protocol that prompted stem cells to self-organize into a mini-kidney.
Deborah Byrd created the EarthSky radio series in 1991 and founded EarthSky.org in 1994. Prior to that, she had worked for the University of Texas McDonald Observatory since 1976, and created and produced their Star Date radio series. Today, she serves as Editor-in-Chief of this website. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named 3505 Byrd in her honor. In 2020, she won the Education Prize from the American Astronomical Society, the largest organization of professional astronomers in North America. A science communicator and educator since 1976, Byrd believes in science as a force for good in the world and a vital tool for the 21st century. "Being an EarthSky editor is like hosting a big global party for cool nature-lovers," she says.
