Regrowing Limbs: Can People Regenerate Body Parts?: Scientific American
A salamander’s limbs are smaller and a bit slimier than those of most people, but otherwise they are not that different from their human counterparts. The salamander limb is encased in skin, and inside it is composed of a bony skeleton, muscles, ligaments, tendons, nerves and blood vessels. A loose arrangement of cells called fibroblasts holds all these internal tissues together and gives the l...
متن کاملIncreased metastatic dissemination in human melanoma xenografts after subcurative radiation treatment: radiation-induced increase in fraction of hypoxic cells and hypoxia-induced up-regulation of urokinase-type plasminogen activator receptor.
Cancer patients showing local failure after radiation treatment have increased probability for developing metastatic disease. The mechanisms behind this observation have not been identified. In the present work, metastatic spread after inadequate radiation therapy was studied by using R-18 human melanoma xenografts as models of cancer in humans. Pimonidazole was used as a hypoxia marker, and hy...
متن کاملPromising perspectives towards regrowing a human arm
Despite the great enthusiasm about tissue engineering during the 1980s and the many significant basic observations made since then, the clinical application of tissue-engineered products has been limited. However, the prospect of creating new human tissues and organs is still exciting and continues to be a significant challenge for scientists and clinicians. A human arm is an extremely complica...
متن کاملTITLE: Analytical evaluation of expected values and variances of the targeting performances for a simplified neural growth model AUTHORS:
Introduction: Spinal cord injury can lead to permanent damage of the ascending and descending neural pathways, which can perpetuate a loss of sensory feeling and motor control in the limbs. Consequently, post-traumatic treatment could consist of regrowing damaged axons to reestablish the pathways affected by the injury; however, this represents a challenge due to the following reason. During de...
متن کاملThe components of regrowing nerves which support the regeneration of irradiated salamander limbs.
Forelimbs of juvenile axolotls do not regenerate when amputated in a previously irradiated region. They usually do regenerate, however, if they have also been denervated shortly after irradiation and well before amputation. Five series of experiments are reported which define the conditions permitting this paradoxical regeneration. Crushing the nerves of the brachial plexus proved a satisfactor...
