First transplant of privately banked cord blood
A family in Brazil had a son who was treated for leukemia. When they later had a daughter, they were offered private storage of her cord blood in case their son relapsed. Instead, the girl developed neuroblastoma and received a transplant using her own cord blood. This was the first ever transplant of privately banked cord blood, and was published by her doctors.
