Scientists solve a major roadblock holding back cancer cell therapy

Researchers have found a reliable way to grow helper T cells from stem cells, solving a major challenge in immune-based cancer therapy. Helper T cells act as the immune system’s coordinators, helping other immune cells fight longer and harder. The team discovered how to precisely control a key signal that determines which type of T cell forms. This advance could lead to ready-made cell therapies that are cheaper, faster, and easier to access.
