Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast to wound healing, or partial regeneration, which involves closing up the injury site with some gradation of scar tissue. Some tissues such as skin, the vas deferens, and large organs including the liver can regrow quite readily, while ...
Regenerative medicine. A colony of human embryonic stem cells. Regenerative medicine deals with the "process of replacing, engineering or regenerating human or animal cells, tissues or organs to restore or establish normal function". [1] This field holds the promise of engineering damaged tissues and organs by stimulating the body's own repair ...
Neuroregeneration involves the regrowth or repair of nervous tissues, cells or cell products. Neuroregenerative mechanisms may include generation of new neurons, glia, axons, myelin, or synapses. Neuroregeneration differs between the peripheral nervous system (PNS) and the central nervous system (CNS) by the functional mechanisms involved ...
Rejuvenation. Rejuvenation is a medical discipline focused on the practical reversal of the aging process. [1] Rejuvenation is distinct from life extension. Life extension strategies often study the causes of aging and try to oppose those causes in order to slow aging. Rejuvenation is the reversal of aging and thus requires a different strategy ...
Liver regeneration is the process by which the liver is able to replace damaged or lost liver tissue. The liver is the only visceral organ with the capacity to regenerate. [ 1 ] [ 2 ] The liver can regenerate after partial hepatectomy or injury due to hepatotoxic agents such as certain medications, toxins, or chemicals. [ 3 ]
Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. [ 1 ] Every species is capable of regeneration, from bacteria to humans. [ 2 ][ 3 ][ 4 ] Regeneration can either be complete [ 5 ...
Healing. With physical trauma or disease suffered by an organism, healing involves the repairing of damaged tissue (s), organs and the biological system as a whole and resumption of (normal) functioning. Medicine includes the process by which the cells in the body regenerate and repair to reduce the size of a damaged or necrotic area and ...
Stem-cell therapy uses stem cells to treat or prevent a disease or condition. [1] As of 2024, the only FDA-approved therapy using stem cells is hematopoietic stem cell transplantation. [2][3] This usually takes the form of a bone marrow or peripheral blood stem cell transplantation, but the cells can also be derived from umbilical cord blood.
