Imagine that a researcher approached you about enrolling your child in a new study he wished to undertake. Your child – who might be as young as 3 1/2 months old – was about to have surgery for congenital heart disease. While your daughter was under anaesthesia, the researcher wanted permission to remove her thymus gland and stitch a full-thickness skin graft from an unrelated adult to her chest. The scientist was curious about the role of the thymus in immune regulation and tissue rejection.
