Cnidarian
Scientists have demonstrated that full-body regeneration in cnidarians, a group of animals that includes the jellyfish and hydra, can be driven by signals from senescent cells [1]. This might be the original purpose of cellular senescence. Why can’t we regrow our arms? There are many examples of amazing regenerative abilities in the animal kingdom, but...
Muscle factor
A paper published today in Nature Aging has shown that a macrophage-regulating factor has a significant impact on muscle regeneration. Healing slows with aging The researchers note two key reasons for the decline of regenerative abilities with aging. The first is stem cell exhaustion, the gradual depletion of stem cells and ensuing lack of functional...
Heart attack
Research published in Cell Stem Cell has described how previously unmodified animals have been given regenerative abilities akin to those of zebrafish, restoring their heart muscle after injury. A TREE of life This study is introduced with a discussion of gene therapy as a field, noting clinical approval for gene therapies against multiple genetic diseases...
Back from the dead
Researchers have been able to achieve substantial recovery of cellular and organismal activity in pigs that had been dead for a full hour [1]. When is it too late? Advances in resuscitation have already moved the boundaries of life and death, making it possible to revive a person several minutes after the heart stops beating....
Skin peeling
Researchers have identified a factor present in the skin of baby mice that controls the formation of hair follicles during their early development. The factor is turned off in adult mice, but when it is turned back on, it allows them to regenerate their skin following injury without scarring, just like baby mice do. SkinSkin,...
Elderly teeth
A recent study published in Nature Communications has outlined an atlas for the various differentiated and stem cell populations found in our teeth.
