What produces GDF11 found in the blood?

[CosmicVoyager]

Greetings,

It has been discovered that transfusions of young blood reverses effects of aging. Would a bone marrow transplant from a younger person produce rejuvinating blood? Or are contents of blood such as GDF11 produced elsewhere?

Thanks
