Abstract
Purpose of the review: This manuscript discusses wound healing as a component of epimorphic regeneration and the role of the immune system in this process.
Recent findings: Epimorphic regeneration involves formation of a blastema, a mass of undifferentiated cells capable of giving rise to the regenerated tissues. The apical epithelial cap plays an important role in blastemal formation.
Summary: True regeneration is rarely observed in mammals. With the exception of transgenic strains, tissue repair in mammals usually leads to non-functional fibrotic tissue formation. In contrast, a number of lower order species including planarians, salamanders, and reptiles, have the ability to overcome the burden of scarring and tissue loss through complex adaptations that allow them to regenerate various anatomic structures through epimorphic regeneration. Blastemal cells have been suggested to originate via various mechanisms including de-differentiation, transdifferentiation, migration of pre-existing adult stem cell niches, and combinations of these.
期刊介绍:
This journal aims to offer expert review articles on the most important recent research pertaining to biological mechanisms underlying disease, including etiology, pathogenesis, and the clinical manifestations of cellular alteration. By providing clear, insightful, balanced contributions, the journal intends to serve those for whom the elucidation of new techniques and technologies related to pathobiology is essential. We accomplish this aim by appointing international authorities to serve as Section Editors in key subject areas across the field. Section Editors select topics for which leading experts contribute comprehensive review articles that emphasize new developments and recently published papers of major importance, highlighted by annotated reference lists. An Editorial Board of more than 20 internationally diverse members reviews the annual table of contents, ensures that topics include emerging research, and suggests topics of special importance to their country/region. Topics covered may include autophagy, cancer stem cells, induced pluripotential stem cells (iPS cells), inflammation and cancer, matrix pathobiology, miRNA in pathobiology, mitochondrial dysfunction/diseases, and myofibroblast.
