During natural tissue regeneration, tissue microenvironment and stem cell niche including cell–cell interaction, soluble factors, and extracellular matrix (ECM) provide a train of biochemical and biophysical cues for modulation of cell behaviors and ...

Neural Regeneration: Lessons from Regenerating and Non-regenerating Systems
Molecular Neurobiology, 2012One only needs to see a salamander regrowing a lost limb to become fascinated by regeneration. However, the lack of robust axonal regeneration models for which good cellular and molecular tools exist has hampered progress in the field. Nevertheless, the nervous system has been revealed to be an excellent model to investigate regeneration.

To present knowledge, macrophages are found in all tissues of the human body. They are a cell population with high plasticity which come with a multitude of functions which appear to be adapted to the respective tissue niche and micro-environment in ...

Axons damaged in a peripheral nerve are often able to regenerate from the site of injury along the degenerate distal segment of the nerve to reform functional synapses. Schwann cells play a central role in this process. However, in the adult mammalian central nervous system, from which Schwann cells are absent, axonal regeneration does not progress to ...

Science of Aging Knowledge Environment, 2004
Humans possess a limited capacity to restore missing or injured body parts. Stimulating this capability might circumvent some of the tissue deterioration that accompanies old age. Other organisms, such as salamanders and planaria, boast remarkable regenerative powers, sprouting limbs or producing entire new individuals.

Current Opinion in Neurology, 1995
The regeneration of nerve is a brilliant example of plasticity within the nervous system. Axonal sprouts form within a few hours of nerve injury and grow vigorously over long distances. Nonetheless, recovery from nerve injury, such as that seen after laceration of distal motor-sensory nerve, is often incomplete.

Reversible reprogramming of cardiomyocytes to a fetal state drives heart regeneration in mice
Science, 2021Description Pluripotency factor drives cardiogenesis Research indicates that the adult mammalian heart does not contain cardiac stem cells and the vast majority of cardiomyocytes do not divide. Heart regeneration is thus limited after injury.

Regeneration: Generations remediated
Time & Society, 2016This paper proposes a model for a dynamic and constructivist perspective on generations. To study synchronous, contemporary interrelations between technology, media and generations, many different methodologies are available. Yet many historical, diachronic studies are marred by flaws and ambiguities in their use of ‘generation’ as a concept.

Liver regeneration after the loss of hepatic tissue is a fundamental parameter of liver response to injury. Recognized as a phenomenon from mythological times, it is now defined as an orchestrated response induced by specific external stimuli and involving sequential changes in gene expression, growth factor production, and morphologic structure.
