In what can be called as a benefit for mankind, scientists from Mexico, Switzerland and US are now capable to grow human body parts, especially reproductive organs and nasal cartilage in labs. Furthermore, they are being successful in implanting these tissues in their patients.
Related to this, two recent researches have backed this latest development.
In the first success story, scientists were able to substitute reproductive organs in young girls who were born with an abnormal or missing uterus. While, in the second article, scientists have highlighted the way they were able to replace portions of noses that were removed after cancer surgery.
Process of Engineering a Reproductive Organ
The scientists started the fix in both the studies by producing a 3D support in the shape and size of the missing organs. The support is completed by a material that dissolves when organ grows. Then, tissues and muscle samples were taken as a base to these cells for organ’s growth. In a couple of weeks, the cells accepted a good grip and they arise to coat the scaffold, forming a tissue which is then implanted successfully in to the patient.
Yuanyuan Zhang, M.D., Ph.D, assistant professor at the Wake Forest Institute for Regenerative Medicine, demonstrates the process to engineer a vaginal organ.
According to the scientists, there have been no complications observed in the procedure so far, even after a year of implantation. Detailed study of the research by Anthony Atala, M.D., director of Wake Forest Baptist Medical Center’s Institute for Regenerative Medicine, was published in “Engineered autologous cartilage tissue for nasal reconstruction after tumour resection: an observational first-in-human trial” via Lancet.
