Regulating the choice of differentiation pathway in progenitor cells is fundamental: (a) to obtain a highly differentiated and pure population for tissue engineering; (b) for the maintenance of the physiological state once the vessel is grafted and (c) to manipulate the progression of the in vivo re-endothelialization of the vascular graft.
To hear the Obama administration tell it, the Filburn decision illustrates just how much leeway the federal government has under the Constitution's commerce clause to regulate the choices individuals make in matters affecting the national economy.
