Sanjay Misra (Rochester, USA) talks to Interventional News about his research into whether stem cell therapy can help AVFs (arteriovenous fistulas) mature and also prevent venous stenosis. The pilot study with a small group of haemodialysis AVF patients led to “promising results” according to Misra, who is planning a larger study to validate the findings. He also discusses the optimal point to deliver the therapy, its future direction and finally, addresses some of the safety concerns around stem cell therapy.
