Regeneration in Vertebrates

open access: yesDevelopmental Biology, 2000
One way or another, all species possess the ability to regenerate damaged tissues. The degree of regeneration, however, varies considerably among tissues within a body and among species, with urodeles being the most spectacular. Such differences in regenerative capacity are indicative of specific mechanisms that control the different types of ...

Synergistic effect of umbilical cord extracellular vesicles and rhBMP-2 to enhance the regeneration of a metaphyseal femoral defect in osteoporotic rats

open access: yesStem Cell Research & Therapy
Background The aim of this study was to evaluate potential synergistic effects of a single, local application of human umbilical cord MSC-derived sEVs in combination with a low dose of recombinant human rhBMP-2 to promote the regeneration of a ...

Single cell sequencing reveals endothelial plasticity with transient mesenchymal activation after myocardial infarction

open access: yesNature Communications, 2021
Endothelial cells play a critical role in the adaptation of tissues to injury and show a remarkable plasticity. Here the authors show, using single cell sequencing, that endothelial cells acquire a transient mesenchymal state associated with metabolic ...

Topology-Aware Node Selection for Data Regeneration in Heterogeneous Distributed Storage Systems [PDF]

open access: yesarXiv, 2015
Distributed storage systems introduce redundancy to protect data from node failures. After a storage node fails, the lost data should be regenerated at a replacement storage node as soon as possible to maintain the same level of redundancy. Minimizing such a regeneration time is critical to the reliability of distributed storage systems.

Virtual regeneration [PDF]

open access: yes, 1998
Regenerating our increasingly polluted, worn-out urban infrastructure is becoming the singly most important challenge facing our cities. Simon Doyle and Michael Batty explain how spatial information technologies and online laboratories can enable many ...

Comparative study of adenosine 3′‐pyrophosphokinase domains of MuF polymorphic toxins

open access: yesFEBS Open Bio, EarlyView.
With the ultimate goal of understanding the association of toxin‐immunity modules to temperate phages, we characterized toxins from three prophages and examined cross‐protection from immunity proteins. The toxins exhibit adenosine 3′‐pyrophosphokinase activity and are toxic in Escherichia coli.

ON THE REGENERATION OF NERVES.

open access: yesThe Lancet, 1897
The author treats the subject under the following heads:— I. A short historical and critical review of the books and papers which have appeared on the subject from the time of Cruik-shank (1776). II. Clinical reports of four cases of secondary suture of nerves as follows:— 1. Suture of the median and ulnar nerves six and a half months after division in

Regeneration in insects

open access: yesSeminars in Cell & Developmental Biology, 1999
@9cIntroduction@21T issues exhibit an impressive ability to respond to a myriad of insults by repairing and regenerating complex structures. The elegant and orderly process of regeneration provides clues to the mechanisms of pattern formation but also offers the hope that the process might one day be manipulated to replace damaged body parts.

Eye on regeneration [PDF]

open access: yesThe Anatomical Record Part B: The New Anatomist, 2005
AbstractLens regeneration in newts is a remarkable process, whereby a lost tissue is replaced by transdifferentiation of adult tissues that only a few organisms possess. In this review, we will touch on the approaches being used to study this phenomenon, recent advances in the field of lens regeneration, similarities and differences between development
