The only cure is a stem cell transplant. De Castro is half-Caucasian and half-Filipino, and the closest stem cell match would have a similar ethnic background. In November, the family urged people — especially those who are of mixed ethnicity — to sign up for the registry to be a potential stem cell donor.

Janetta, seen holding Boston in hospital, will begin the process to be his stem cell donor on Friday.
