Dr. William Haseltine, CEO of Human Genome Sciences Inc., told in a November 2000 story, ‘Once we realize, in essence, what our cells know, health care will be revolutionized, giving birth to regenerative medicine – eventually involving the prolongation of life by regenerating our ageing bodies with younger cells.’ He added that we will ultimately communicate with our internal waterfall of youth by studying the language of the cell and chemical processes that turn on / off cell repair. This is not all research on stem cells, though nanotechnology and regenerative medicine can do it. Visit Carolina Cell Therapy.
In order to aid people suffering from traumatic injury and missing arms, regenerative medicine has immense promise. For eg, take Lee Spievack. He sliced off his fingertip while working with an aeroplane propeller for a hobby shop. His brother happens to be a medical researcher and told him to apply his wound with a special substance.
The whole fingertip of Spievack had developed back after four weeks; the muscle, the nail, the blood vessels and everything! The powder was produced from a pig bladder’s extracellular matrix containing proteins, connective tissues, and stem cells. “It advises the body to initiate this tissue regrowth phase,” says Dr. Steven Badylak of Pittsburgh University. In principle, if a individual is able to regrow a body organ, he said, they may also regrow a missing leg.
Another focus of regenerative medicine, using adult stem cell research as a springboard, is to replace ailing body parts in a more natural way. “The cells have all the genetic data required to create new tissues,” explained Dr. Anthony Atala of the Wake Forest Institute. “That is what they have been programmed to do.
“And your heart cells are programmed to produce more heart tissue, your bladder cells are programmed to make more bladder cells.” Clinical experiments are currently ongoing to establish a patch of bladder cells or kidney cells or liver cells that will act to become a completely functional implant of surrounding tissue. Scientists would one day be able to produce organs from their own cells or activate the cells to rebuild the tissue internally, instead of going through the hassle of seeking eligible donors.
In regenerative medicine, much of the progress being made involves studying animals that possess this asset. Salamanders, for example, may re-grow tails or lose limbs. Most research on stem cells suggests that mammals are capable of regenerating the skin, bone, and liver, but are unable to regenerate entire limbs on their own. If scientists can exploit regenerative capacities, so it is feasible to prolong the life expectancy of humans forever and to discover innovative approaches to counteract the symptoms of ageing.
