Ever since medical science first started tinkering with various human parts like organs, scientists have dreamed of providing "cures" or replacement of human parts for known pathological defects by active intervention. They started off with the heart, then extended transplants to include kidneys, liver, lungs, pancreas, intestine and thymus. Having mastered various ways of combatting the difficulties of immunological rejection, they extend similar notions to tissues transplant. Nowadays, surgeons regularly perform grafting of bones, tendons" (musculo-skeletal grafts), cornea, skin, heart valves, nerves and veins etc.With the completion of the Human Genome Project "HGP" which started in 1990, scientists have been hard at work to synthesize some new and hopefully better human genome and in June 2016, they announced plans to do so under a project called "HGP-Write".
