Are my stem cells too old to work?

A close up of a cell in the water

Dear Dr. Raff,

My doctor told me that my stem cells are too old to be productive in cell regenerative therapy. I am 76 years old. Is this true?

No, it is not true. Bone marrow is the place where stem cells reproduce the exact duplicates of themselves. One of our past stem cell’s patient is now 87, who had been treated last year for knee pain and limited movement. He stated that his knee has exceedingly enhanced, the least pain and better fluidity. Everything is much better, even his golf game.

Sincerely, Dr. Raff
