Researchers at Chulalongkorn University transformed canine fat tissue into functional insulin-producing cells, paving the way for a lasting cure for pet diabetes.
The breakthrough, spearheaded by the Veterinary Stem Cell and Bioengineering Innovation Center (VSCBIC) at Chulalongkorn University, offers a potential cure for a condition that affects roughly one in every 300 dogs and cats.
In dogs, the condition mirrors human Type 1 diabetes: the immune system destroys the pancreatic “beta cells” responsible for creating insulin, leaving the body unable to regulate blood sugar levels naturally.
Until now, the only treatment has been lifelong, twice-daily insulin injections – a routine that places a heavy emotional and financial burden on pet owners.
To solve the problem, the research team focused on stem cell technology to manufacture brand-new, healthy beta cells from scratch.
After years of testing various biological sources – including bone marrow and oral tissue – the scientists discovered that adipose (fat) tissue was the ideal candidate.
Fat tissue yields up to 500 times more stem cells than bone marrow, carries minimal medical risk, and is routinely removed during standard pet spaying or neutering procedures.
The Chulalongkorn team used a “nature-inspired” approach, mimicking how organs naturally develop in an embryo.
By combining genetic reprogramming – introducing specific genes directly into mesenchymal stem cells – with a precisely timed sequence of chemical growth factors, the researchers essentially re-educated the cells to take on a completely new role.
Rather than relying on vague or untested stem cell treatments currently marketed to consumers, the Chulalongkorn team is adhering to rigorous clinical standards.
The team expects to begin clinical trials in diabetic dogs within the next two to three years, with a commercial treatment slated to follow shortly after.
Beyond pet diabetes, the underlying cellular framework could eventually be adapted to treat organ degeneration in feline and human patients alike, including kidney, liver and eye disorders. — The Nation/ANN
