REDONDO BEACH, Calif. -- Maya Chamberlin is a beautiful, smart and loving 4-year-old girl who has become gravely ill with a disease called Hemophagocytic lymphohistiocytosis, or HLH.

She needs donated bone marrow that very closely matches her own for a transplant.

The best chances of matching are with a sibling, but Maya's brother is not a match.

The next best chance is with a parent.

But they're not a match either.

So, they need the help of the public.
