Millions of people with knee injuries could benefit from a new type of stem cell bandage treatment if clinical trials are successful. The world's first clinical trial for the treatment of patients with torn meniscal cartilage has received approval from the UK regulatory agency, the MHRA1, to commence.
The current treatment for the majority of tears is the removal of the meniscus, a procedure that often results in the early onset of osteoarthritis.
The Phase I trial, one of the first in the UK to be approved using stem cells, will treat meniscal tear patients with a cell bandage product, seeded with the patient's own, expanded, stem cells.
The cell bandage, produced by Azellon Ltd, a University of Bristol spin-out company, is focused on the research, development and commercialisation of an adult autologous (patient's own) stem cell technology which in vitro (tissue culture) has shown great promise for the healing of meniscal tears.
The trial is designed primarily to test the safety profile of Azellon's cell bandage in ten meniscal tear patients, but some information on whether or not it works will also be obtained. The bandage, containing the patient's own stem cells will be implanted in a simple surgical procedure using a specially designed instrument that helps to deliver the cells into the injured site as a first-line treatment in place of removal of the meniscus. Patients will be closely monitored for safety over a five-year follow-up period.
Professor Anthony Hollander, Chief Scientific Officer at Azellon Ltd and Head of the School of Cellular and Molecular Medicine at the University of Bristol, said: "The approval we have received from the MHRA is an important milestone in the development of stem cell therapies in the UK. These cells hold much scientific and medical promise but we can only know if they work or not by testing them out in clinical trials."
Professor Ashley Blom, Professor of Orthopaedic Surgery at the University of Bristol, added: "The effective repair of meniscal tears would represent a significant advance in treatment, particularly for younger patients and athletes by reducing the likelihood of early onset osteoarthritis, and would offer an exciting new treatment option for surgeons."
More than 900,000 patients have meniscal tears every year in Europe with perhaps 800,000 to one million meniscal repairs in US making the total market 1.7 million meniscal tears per year. Seven per cent of meniscal surgeries are repairs in the 'red' zone, the rest (1,581,000 tears) remain total or partial menisectomies. Meniscus tears normally occur in active and younger people (estimated 80 per cent of meniscal patients are younger than 50). Meniscus tear is a common sports injury and is especially prevalent amongst competitive athletes in football (including US and Australian rules), rugby and basketball. Patients who have partial or total menisectomy have an increased risk of developing osteoarthritis over the following 4.5 to eight years.
Azellon Ltd is funded by the Wellcome Trust, Technology Strategy Board and early stage investors IPGroup, Oxford Technology and Wyvern Seedcorn fund.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
