Who owns research samples after they are obtained?
My views on Clinical Informatics Ethics:- Havasupai Medical Genetics study.

These samples though they are known as body “parts” of the subject as blood and tissue, they carry more than the names attached to them; the blueprint “DNA” of the subject who is unique and distinct from any other beings. In this case I would think the fact that "no any human can own other human whole or in part" thence no consent should transfer human being ownership.
