Actor Martin Milner is seeking the public's help in finding a bone marrow donor for his leukemia-stricken daughter.

Milner, who starred in the TV series "Route 66" and "Adam 12," said a marrow transplant may be the only hope for 45-year-old Amy Milner, and no suitable donor has been found among family members or on the national registry.

Milner hopes widespread blood testing will help his daughter and others.

"There's a good likelihood that somebody else could be saved, somebody not related to us at all. . . . There are a lot of people waiting for good news," Milner said.

His daughter Amy, a single mother who lives in Encinitas, was diagnosed with acute myeloid leukemia in February 2003.
