Regeneration of Mammalian Body Parts
نویسنده
چکیده
Miracle mice When, in 1994, Dr Ellen Heber-Katz of the Wistar Institute in Philadelphia was monitoring marked mice in a group that she used as experimental animals in connection with her research on multiple sclerosis, she received a surprise. The marked mice could not be found! They had punch holes in the ears for identification, and at first it seemed as though a mistake had been made, for now all of the mice had ears without any holes in them. The experiment was repeated and it became clear that the holes were repairing themselves in about three weeks and leaving no scars. Initially, a number of immature cells formed along the edges of the hole to give a regeneration-blastema which rapidly subdivided so that the hole gradually closed up. There was perfect re-formation of cartilage, blood vessels, and skin.

Macrophages are required for adult salamander limb regeneration.
The failure to replace damaged body parts in adult mammals results from a muted growth response and fibrotic scarring. Although infiltrating immune cells play a major role in determining the variable outcome of mammalian wound repair, little is known about the modulation of immune cell signaling in efficiently regenerating species such as the salamander, which can regrow complete body structure...
متن کاملAutonomous development of parts isolated from primitive-streak-stage mouse embryos. Is development clonal?
The relationship between growth rate and regionalization of amphibian, bird and mammalian embryos is briefly reviewed. In contrast to the others, mammals start gastrulation with few cells but accelerate cell proliferation coincidentally. Experiments are described which demonstrate (1) autonomous development of pieces isolated surgically from such mouse embryos, and (2) an absence of regeneratio...

Explants of leaves, petals, anthers, styles and ovaries of C. speciosus, C. cancellatus, C. gilanicus and C. almehensis were cultured on LS media with three different combinations of NAA and BAP in the dark. Callus and neoformant organs (leaf and corm-like structure and ordinary and contractileroots) were fomd on some of these explants. Corm explants from these species were also cultured on...
متن کاملTissue nonautonomous effects of fat body methionine metabolism on imaginal disc repair in Drosophila.
Regulatory mechanisms for tissue repair and regeneration within damaged tissue have been extensively studied. However, the systemic regulation of tissue repair remains poorly understood. To elucidate tissue nonautonomous control of repair process, it is essential to induce local damage, independent of genetic manipulations in uninjured parts of the body. Herein, we develop a system in Drosophil...
متن کاملThe zebrafish as a model of heart regeneration.
Regeneration is a complex biological process by which animals can restore the shape, structure and function of body parts lost after injury, or after experimental amputation. Only a few species of vertebrates display the capacity to regenerate body parts during adulthood. In the case of the heart, newts display a remarkable ability to regenerate large portions of myocardium after amputation, al...
متن کاملUnlocking the Neurogenic Potential of Mammalian Müller Glia
Müller glia (MG) are the primary support cells in the vertebrate retina, regulating homeostasis in one of the most metabolically active tissues. In lower vertebrates such as fish, they respond to injury by proliferating and reprogramming to regenerate retinal neurons. In mammals, MG may also react to injury by proliferating, but they fail to initiate regeneration. The barriers to regeneration c...
