On Friday, hundreds of City of Hope transplant recipients met the people who saved their lives.
One of those transplant recipients was the 10-time Emmy award winner, Steven Bochco.
Bocho created, wrote and/or produced hit TV shows Hill Street Blues, NYPD Blue and Doogie Howser M.D.
But he recently faced a real-life drama of his own: a rare form of Leukemia.
"He was quite ill when he was diagnosed...The odds of him surviving without a transplant were probably close to zero," said Doctor Stephen Forman.
In real life, it wasn't a young doctor who saved Bochco's life -- it was a young donor.
Jon Kayne signed up to be a bone marrow donor when he was 21.
"I lost a grandfather who I was very close with when i was 13 --- i would have done anything - so would any of my family members to have extended the time that he could have spent with all of us," said Kayne.
When he was 23, he got a call he was a match. It was during the same time he found another grandparent was diagnosed with cancer.
Although he'd have helped anyone, what Kayne didn't know until Friday morning, is that he was a fan of the person whose life he saved.
"You think a little bit about who the person is on the other side, but until you meet ...it's incredible," said Kayne.
Bochco says he was curious what motivated someone so young to save a life.
"When i was 23 years old, I had my head up my tush," said Bochco.
He says the transplant gave him a future.
"Jon has provided me with bonus time," said Bochco.
And maybe even a little of his past:
"There's a reason why i go to strip clubs every night. Because I have this -- what are you 25? I have a 25-year-old young man's DNA," said Bochco.
It's unclear if Botcho's experience will be a plot in one of his future shows.
But he says meeting Jon will be the final part to one of his real life scripts.
"It's going to be published by Amazon. With Jon's permission i'm going to write an epilogue before they finally put it out," said Bochco.
