all heard that the lizard is able to recover the discarded tail.Of course, higher in the hierarchy of the body, it is more difficult it regeneration.It happens at different levels of the organization, from the cell to the level of tissue at the level of a mammal regeneration does not occur, but in a single body - completely.Record holder - the liver.So the legend of Prometheus, whose liver pecked eagle, and it grew again during the night, has some real basis.Regeneration - the process of restoring the shape and function of the damaged organ, tissues and cells.
himself or help?
an entire field of medicine that puts the task of stimulating the formation of new cells and tissues in the diseased or damaged organs.But even without foreign intervention the human body is able to regenerate - heal wounds, scarring burns fused bones.Cell regeneration enables you to create new structures to replace those destroyed.That is, even without special effects the body is capable of much.Regeneration - is aimed at restoring the activity of the body's functions.That is for your body is the primary organ of the possibility or impossibility to do this or that.
many specialties, one expert
type of medical research engaged with this issue, called regenerative medicine or tissue engineering.If you fancy yourself in vitro grown organs and tissues, it is not quite what scientists regenerativisty busy.In fact, to work in this area, researchers should have experience in genetics, biology and engineering of any level.That is, it is an interdisciplinary field, and experts is that small.
work on the site
regeneration - is not the creation of alternative in vitro, is the work on a living person.Outside the body multiply the cells, and there are two approaches.The first breed's own cells, the second - the donor.It is understood that the donor can cause ottorozhenie, so its always better.In addition, immune suppression that occurs when using them, worsens their own regeneration.It is desirable to use for these purposes stem cells.Their huge advantage - the unlimited ability to divide, that they are not the old ones.But they are quite difficult to detect in the body for autodonorstva.Perhaps in the future everyone will preserve the umbilical cord blood of their own: it is a lot of stem cells ideally suited for each type.Now, this resource either thrown out or dealt secretly with money cosmetic companies.
tissue regeneration proceeds with a stable, but low speed - 1 mm per day, the regeneration points may be several: that is, at the same time will heal the bruises, scratches and burns.Regeneration - the process of cranky that he was well, it is important to proper nutrition.If you are restoring, you need to take time off from dieting, you need a protein-carbohydrate meals increased caloric content, because the protein will go to recovery, and carbohydrates will guarantee that the body will not have to destroy their own proteins.
