Expanding cytotoxic T lymphocytes from umbilical cord blood to target three viruses

What’s Known
Children’s National Health System is the only pediatric hospital in the nation that grows personalized T-cells from naïve cord blood (CB), training these CB-derived cells to simultaneously fight adenovirus, cytomegalovirus, and Epstein-Barr virus to control viral infections after transplantation. Here are a number of the critical steps during that three-month manufacturing process.
