Health IT: Data and Sample Ownership in a Research Study,

Who owns research samples after they are obtained?
My views on Clinical Informatics Ethics:- Havasupai Medical Genetics study.
The research group can hardly own sample in a research that involves biospacimen that can be traced back to the owner. This fact I think, sets boundaries to what should define the relationship of each part in the study; a researcher meant to answer the research question and the subject willingly and knowingly consents to be a source of such information.
 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.
