On page 433 , Morrison et al. show that the regeneration of newt limbs hinges on the activation of muscle satellite cells—t...
متن کاملRole of neutrophil-derived matrix metalloproteinase-9 in tissue regeneration.
Ischemic tissue regeneration depends on neovascularization, the growth of new blood vessels. Bone marrow (BM)-derived cells, including neutrophils, have been shown to contribute to neovascularization during hind limb ischemia and inflammation. Neutrophils produce a broad array of angiogenic growth factors and proteases, which promote remodeling of arterioles into arteries through proteolytic me...
متن کاملStructural basis of matrix metalloproteinase function.
The matrix metalloproteinases (MMPs) constitute a family of multidomain zinc endopeptidases which contain a catalytic domain with a common metzincin-like topology. The MMPs are involved not only in extracellular matrix degradation, but also in a number of other biological processes. Normally, their proteolytic activity is regulated precisely by their main endogenous protein inhibitors, in parti...
متن کاملThe newt ortholog of CD59 is implicated in proximodistal identity during amphibian limb regeneration.
The proximodistal identity of a newt limb regeneration blastema is respecified by exposure to retinoic acid, but its molecular basis is unclear. We identified from a differential screen the cDNA for Prod 1, a gene whose expression in normal and regenerating limbs is regulated by proximodistal location and retinoic acid: Prod 1 is the newt ortholog of CD59. Prod 1/CD59 was found to be located at...
متن کاملExpression and activity of the newt Msx-1 gene in relation to limb regeneration
The Msx-1 homeobox gene is expressed in various contexts during vertebrate development, including the progress zone of the avian and mouse limb bud. Expression of mouse Msx-1 in a cultured myogenic cell line conferred a transformed phenotype and inhibited fusion into myotubes. It has been proposed that Msx-1 expression is required to maintain certain cells in a proliferating and undifferentiate...
