regeneration

Detached sea cucumber tissue survived, healed, and grew for years in natural seawater, revealing a remarkable new model for regeneration and biomedical research. A chance observation has led scientists to a discovery that challenges one of biology’s most basic assumptions: that detached animal tissue eventually dies. Instead, researchers found that tissue removed from a sea [...]

While human beings have some impressive self-healing capabilities, we're nowhere near the level of salamanders...

Researchers have successfully regenerated skeletal and connective tissue, although the new tissue was not perfectly formed. The result demonstrates a critical step forward in limb regeneration. For centuries, scientists have viewed the inability to regrow lost body parts as a major biological limit for humans and other mammals. Salamanders and some other animals can regenerate [...]

Scientists studying axolotls, zebrafish, and mice have uncovered a shared set of genes that may one day help humans regrow lost limbs. By identifying powerful “SP genes” involved in regeneration, researchers discovered that disabling these genes stopped proper bone regrowth in salamanders and mice. They then used a gene therapy inspired by zebrafish biology to partially restore regeneration in mi…

Of course, humans can regrow damaged skin in the area—but also bone, tissue, and nerves.

Some of the most "ribbiting" research happening on campus stems from regeneration - the science of reforming, repairing, or regrowing lost tissue. This is the prerogative of researchers in the Tseng Lab, which recently observed that certain frog larvae can regrow their eyeballs. "We're building a blueprint for eye tissue regeneration," said Kelly Tseng, professor in the School of Life Sciences.

Oxygen and hyaluronic acid may play a role in tissue recovery and regeneration, two new studies suggest

A snail that regrows its eyes may hold the genetic clues to restoring human sight. Human eyes are intricate organs that cannot regrow once damaged. Surprisingly, they share key structural features with the eyes of a freshwater apple snail, an animal capable of fully regenerating its vision. Alice Accorsi, assistant professor of molecular and cellular [...]

Planaria can't replace a missing head until after the tail develops sufficiently.

Cut off any part of this worm’s body and it will regrow. This is the spectacular yet mysterious regenerative ability of freshwater flatworms known as planarians. The lab of Whitehead Institute Member Peter Reddien investigates the principles underlying this remarkable feat. In their latest study, published in PLOS Genetics on February 6, first author staff scientist M. […] The post A planarian’s …

Two individual comb jellies can fuse into a single organism, providing an incredible feat of regeneration rarely seen in the animal world. The post Fused comb jellies share their secrets of regeneration appeared first on Advanced Science News .

If only humans could master regeneration. It seems like that would open the door to far better health. Maybe to longer life too. We can see how many other creatures innately can regenerate organs. I can see it in the lizards that run around in my garden. Every now and then I see one with […] The post Recommended reads: regeneration by fasting & cancer, Time’s kid of the year, Hayflick death appea…

When Albert E. Almada PhD ’13 embarks on a new project, he always considers two criteria instilled in him during his time as a graduate student in the Department of Biology at MIT. “If you want to make a big discovery, you have to approach it from a unique perspective — a unique angle,” Almada […] The post What can super-healing species teach us about regeneration? appeared first on MIT Departmen…

When animals experience a large injury, such as the loss of a limb, the body immediately begins a wound healing response that includes sealing the wound site and repairing local damage. In many animals, including humans, when the local wound site is taken care of, this response ends. However, in some animals, the initial wound […] The post When equinox appears, repair transitions into regrowth ap…

Another busy week including on the grant writing treadmill or should I say Mobius strip, but I’m always on the lookout for new reading and this week a lot popped up on regeneration. Also, a paper on healing and scarring. I regularly write about stem cell journals. For a long time, it seems like Cell Stem […] The post Stem cell reads: regeneration, 8C, MYC, CRISPR babies appeared first on The Nich…

Global Journal of Otolaryngology - Juniper Publishers Abstract Dental Stem cells are undifferentiated cells isolated from tooth and associated structures. Dental stem cells can be easily obtained from both adult and deciduous teeth, the periodontal ligament, the apical papilla and the dental follicle. Their subsequent differentiation can be utilized to replace the lost tooth structures. Here…

7 July 2015 A Travelling Fellowship from Development gave Alice Accorsi the inspiration and the means to collaborate in her research into the freshwater gastropod, Pomacea canaliculata. It brought her the opportunity to spend three months at the Stowers Institute for Medical Research in Kansas City, USA where she could develop her thinking, learn new […] The post Inspiring regeneration appeared f…

Posted by Natalie DeWitt for Attila Csordás The sea squirt can regenerate its whole body from the vasculature. Here Attila Csordás interviews Ayelet Voskoboynik, postdoctoral fellow from the Weissman lab, Stanford University, to tell us how. Their findings were published in a recent paper, entitled Striving for normality: whole body regeneration through a series of abnormal generations (FASEB Jou…
