The annual regrowth of deer antlers is a unique case of extensive appendage regeneration in mammals. This review compares basic aspects of antler regeneration with epimorphic regeneration in other vertebrate taxa. The mesenchymal cells that build up the regenerating antler are not derived from dedifferentiated cells in the pedicle stump, but from the proliferation of cells of the pedicle periosteum; and based on different lines of evidence it has more recently been suggested that the pedicle periosteum contains stem cells that are periodically activated to produce a new antler. This constitutes a difference to urodele limb regeneration, where the blastema is (largely) formed from dedifferentiated cells. Antler regeneration involves healing of the large casting wound with no or only minor scarring, making the antler an interesting model for the control of scarring in mammals. Contrary to urodele limb regeneration, antler regrowth does not depend on a functional nerve supply. In our view, a comparative analysis of different regeneration phenomena, including antler regeneration, probably offers the best chance for achieving significant progress in regenerative medicine.

Developmental neuronal remodeling is a crucial step in sculpting the final and mature brain connectivity in both vertebrates and invertebrates. Remodeling includes degenerative events, such as neurite...
Bone and antler collagen δ(13) C and δ(15) N values are often assumed to be equivalent when measured in palaeodietary, palaeoclimate and palaeocological studies. Although compositionally similar, bo...
Studies of annelid regeneration have greatly increased in frequency in recent years, providing new insights into the developmental basis and evolution of regeneration. In this review, we summarize rec...
Salamanders are capable of regenerating amputated limbs by generating a mass of lineage-restricted cells called a blastema. Blastemas only generate structures distal to their origin unless treated wit...
When peripheral axons are damaged, neuronal injury signaling pathways induce transcriptional changes that support axon regeneration and consequent functional recovery. The recent development of bioinf...
For patients who have one or two metastases in the brain, the tumor(s) can often be removed with surgery to relieve symptoms from the tumor(s) and to improve survival. However, about half ...

The difference between two images on the retina when looking at a visual stimulus. This occurs since the two retinas do not have the same view of the stimulus because of the location of our eyes. Thus the left eye does not get exactly the same view as the right eye.
Procedures for enhancing and directing tissue repair and renewal processes, such as BONE REGENERATION; NERVE REGENERATION; etc. They involve surgically implanting growth conducive tracks or conduits (TISSUE SCAFFOLDING) at the damaged site to stimulate and control the location of cell repopulation. The tracks or conduits are made from synthetic and/or natural materials and may include support cells and induction factors for CELL GROWTH PROCESSES; or CELL MIGRATION.
A preparation consisting of PLATELETS concentrated in a limited volume of PLASMA. This is used in various surgical tissue regeneration procedures where the GROWTH FACTORS in the platelets enhance wound healing and regeneration.
A cosmetic technique that uses PLASMA GASES in therapeutic treatment to help achieve skin REJUVENATION or REGENERATION and delay SKIN AGING.
The horn of an animal of the deer family, typically present only in the male. It differs from the HORNS of other animals in being a solid, generally branched bony outgrowth that is shed and renewed annually. The word antler comes from the Latin anteocularis, ante (before) + oculus (eye). (From Webster, 3d ed)
