Successfully grown human organs open a new chapter in medical science


In the scientific community, news has recently emerged that could forever change the future of medicine and organ transplantation. Scientists have succeeded in growing human organs in the laboratory, opening new possibilities for transplantation and the treatment of many diseases. This discovery, which includes the development of complex organs such as kidneys, blood vessels, and intestines, represents a significant step toward the production of fully functional human tissues that could be used in treatment and as an alternative to traditional transplantation methods.


Breakthrough in kidney growth in the laboratory


The kidney is an organ crucial for filtering waste and maintaining chemical balance in the body, and kidney disease represents a global health problem. According to scientific reports, one in nine adults suffers from some form of kidney disease. The new discovery by scientists from Dr. Joseph Bonventre's laboratory at Brigham and Women's Hospital has given hope for the future possibility of creating kidneys under laboratory conditions. By using two main building blocks – metanephric mesenchyme and ureteric bud – they managed to create functional kidney tissue, which can further be used to explore new therapies for kidney diseases and to develop drugs for patients with renal insufficiency. This technology opens up the possibility of personalized treatment and reduces the need for kidney donors, often unavailable to patients waiting for transplantation.


Blood vessels as the foundation for the production of complex organs


The development of blood vessels has posed yet another challenge for scientists in their efforts to create complex human organs in the laboratory. A team of scientists from Harvard University has developed advanced 3D technology that allows the creation of a complex network of blood vessels that mimic the natural vascular architecture of human tissues. By applying a method known as co-SWIFT, scientists have succeeded in producing networks of blood vessels in heart tissues, and after four days of perfusion with a fluid that mimics blood, they recorded synchronized beating of heart cells. This achievement represents a significant step toward creating fully functional organs, which could enable personalized treatment for patients based on their specific needs.


Advances in the growth of intestines and other organs


One of the challenges was also the growth of digestive organs, and scientists from Tokyo Medical and Dental University have succeeded in developing "mini-intestines" or intestinal organoids that closely resemble functional intestines in the human body. These mini-intestines can now be used to study intestinal diseases, but also to develop new therapies, especially for rare syndromes like Cronkhite-Canada syndrome. Advances in laboratory-grown intestinal organoids open possibilities for a deeper understanding of gastrointestinal diseases and finding new drugs, while also reducing the need for animal testing.


Future perspectives - from laboratories to patients


These laboratory successes represent a significant step forward in regenerative medicine and the possibilities for treating diseases that were previously almost incurable without a suitable donor organ. Scientists worldwide hope that in the near future they will be able to grow entire organs for transplantation, which could drastically reduce the need for donor organs and make transplantations less dependent on donors. With the support of new technologies such as bioprinting and organ regeneration, a world can be imagined where patients receive customized, functional organs, reducing the risk of rejection and the need for immunosuppressive drugs after transplantation.


Despite significant progress in this field, scientists are aware that many challenges still lie ahead. Currently, laboratory-grown organs are used for research and testing and are not yet ready for clinical application. However, significant steps have been taken towards the goal of ensuring that in the future patients are no longer condemned to long waits for a suitable organ, which could save countless lives worldwide.
