Nevertheless, this was a huge leap towards whole lung regeneration and transplants for humans, which has already taken another step forward with the lung regeneration of a non-human primate. [63] Cystic fibrosis is another disease of the lungs, which is highly fatal and genetically linked to a mutation in the CFTR gene.
[19] [20] Explaining the new class of therapies that such cells could enable, he used the term "regenerative medicine" in the way that it is used today: "an approach to therapy that ... employs human genes, proteins and cells to re-grow, restore or provide mechanical replacements for tissues that have been injured by trauma, damaged by disease ...
Sculpted image of the leg of Miguel Pellicer in an arch of the Templo del Pilar in Calanda. The Miracle of Calanda is an event that allegedly took place in Calanda, Spain in 1640, according to 17th century documents. The documents state that a young farmer's leg was restored to him after having been amputated two and a half years earlier.

Unlike the limited regeneration seen in adult humans, many animal groups possess an ability to completely regenerate damaged tissue. [4] Full limb regeneration is seen both in invertebrates (e.g. starfish and flatworms which can regenerate fully functioning appendages) and some vertebrates, however in the latter this is almost always confined to the immature members of the species: an example ...
A salamander can not only regenerate a limb, but can regenerate the lens or retina of an eye and can regenerate an intestine. For regeneration the salamander tissues form a blastema by de-differentiation of mesenchymal cells, and the blastema functions as a self-organizing system to regenerate the limb. [13]
Becker studied regeneration after lesions such as limb amputation, and hypothesized that electric fields played an important role in controlling the regeneration process. He mapped the electric potentials at various body parts during the regeneration, showing that the central part of the body normally was positive, and the limbs were negative.
Two human arms and a human leg were found in a park on Long Island, New York, on Thursday morning, and police are investigating how the body parts ended up there.
