Scientists test if standardizing immune cells makes transplants safer and more predictable

This study aims to find out if giving patients a specific, standardized dose of immune cells (called CD3+ T cells) during a stem cell transplant from a matched sibling leads to better and more predictable results. Researchers will give 20 adult patients a carefully measured dose of these cells to see if it reduces complications like graft-versus-host disease and improves recovery. The goal is to make the transplant process more reliable and easier to manage for future patients.
