Scientists in Glasgow have made a breakthrough, which could make a big difference to sufferers of diabetes by helping to treat their foot ulcers.
Foot ulcers are a common side effect of diabetes caused by nerve and blood vessel damage. An estimated 15% of diabetes patients develop foot ulcers as a result of the condition.
The impact of foot ulcers can be severe – for some patients the severity of the ulcers eventually leads to amputation.
Hope for Treatment
This latest study carried out by researchers at the Glasgow Caledonian University has managed to reprogramme human cells using leftover skin tissue from surgery to replicate wounds from diabetic foot ulcers.
The team used donor skin tissue samples from people with type 2 diabetes. From these they created batches of human stem cells ready to be reprogrammed into different types of cells including brain and nerve cells. It is hoped that in the future these cells will be able to be used to repair tissue and skin damage resulting from foot ulcers, and hopefully prevent the need for amputation.
The research is part of a three-year project funded by Animal Free Research UK who is hoping to develop new treatments for foot ulcers that do not need to be tested on animals, as currently is the case.
Professor Ann Graham, lead author of the study said:
“Over 135 diabetes-related amputations are carried out each week in the UK. We know that this is a growing problem and we hope that our work can inform research and aid others who require access to human material for medical research.”
Future research by the team will examine the links between type 2 diabetes and Alzheimer’s disease, as well as diabetic wound healing and psoriasis.
