Stem Cells Could Repair Cataracts

Cataracts are the most common reason for blindness in today’s world. Cataracts are when the lens in your eye becomes clouded and while often associated with the elderly, it also affects the young and even infants. While there is a surgical option to address this issue, a group in China thinks that stem cells could repair cataracts, giving people back their sight.

Currently in order to remove Cataracts, the patient needs to undergo surgery. Removing the lens that has become cloudy, and inserting either a transplanted or even artificial lens granting them back their sight. With millions undergoing the surgery, it’s not uncommon for complications and even diminished results ending with people requiring glasses to assist in their eyesight.

Typically these complications affect 24 our of 25 infants who have to undergo this surgery, but by encouraging the infant’s own stem cells, only one out of twelve infants in the trail had a complication.

While stem cells are a case for hope, with adults generating the stem cells used in this case way into their 40’s, this could become the first step in allowing people to regenerate their lenses in a semi-natural way. This could result in reducing or even removing the issue of cataracts coupled with a much smaller and less invasive technique.

UK University Wins Funding for Robotic Stem Cell Factory

We as the human race are in an almost neverending fight with nature, although there really isn’t any doubt who will in the end. That doesn’t mean that we can’t put up a fight and make the best of everything until then. One of the main areas that we fight in are the diseases that plague us as a race. One of the ways that we combat this is with stem cells, but they are too costly, time-consuming, and labour intensive to be a viable solution for a mass production large enough to cover everyone.

One of the ways that this can be improved upon is with the use of robots that don’t need downtime, work more precise, and don’t require a salary either. The EU has set aside €6 million for the project and the Aston University in Birmingham is going to play a critical role in this project to develop a robotic stem cell factory, which will reduce the cost of manufacturing adult stem cells and open up the opportunity to produce new therapies for a range of conditions.

“Stem cell therapies have the potential to treat currently unmet patient needs and provide therapies for conditions such as diabetes, heart disease and Parkinson’s. However, current manufacturing methods for adult stem cells are costly, time-consuming and labour-intensive, so will be unable to satisfy the expected patient demand,” said Dr Qasim Rafiq, academic lead for the project at Aston University and Lecturer in Bioprocess Engineering.

The AUTOSTEM consortium, coordinated by NUI Galway in Ireland, has received the funding through the European Commission’s Horizon 2020 programme to address the current challenges in manufacturing stem cells. The new system will be developed as a scalable, automated robotic system for the growth of adult stem cells.

The clinical product being developed involves isolating and purifying adult stem cells from the bone marrow before growing these in bioreactors to achieve sufficient numbers of cells to treat thousands of patients. This work will be conducted in a sterile, aseptic cleanroom facility operated by a robotic system. That’s another benefit of using robots over a human workforce.
