Just Imitating Nature in an Industrialized Manner Tissue and organ regenerative capacities have been developed by all living multicellular organisms including men, as an evolutionary advantage mechanism in order to survive. The general process of regeneration is a common normal feature observed with different modalities and intensities in all kind of animals, humans and even plants. It follows several basic universal rules in all species. Between them, adult stem cells are crucial for all these physiological tissue renewal and regeneration events after injury or disease. Also, the idea of spherical structures is important and persistent, from a cell to a colony, and even in the development of an embryo. This shape and its elementary forces are seen in equilibrium in all nature, from atoms to planets and stars. In this way, amphibians can develop blastemas in their amputated limbs in order to regrowth, and plants have meristems as self-unique-organizing regenerating systems.
