Human tissue. Who owns bone, sinew, corneas, and other saleable body parts? Who can consent to its post-mortem removal? What do state statutes say about the nonconsensual removal of human tissue? Why does federal law prohibit the sale of solid organs but permit the sale of other human tissue (and blood, sperm, and ova)? Do the rules that govern these activities sufficiently protect the interests that need to be protected? Or do they go too far and discourage an efficient market?
