Regeneration in sea lilies
Article Abstract:
Sea lilies or stalked crinoids are capable of regenerating not only all their arms but also their crowns. Experiments with the species Metacrinus rotundus provide the first evidence that autotomy, or the voluntary detachment and subsequent regrowth of a body part, does occur among sea lilies. Moreover, the upper most region of the sea-lily stalk including the basal plates is able to regrow the entire crown. Food and materials from the stalk, particularly the upper five centimeters, are used to regenerate the crown.

Help from within for damaged axons
Article Abstract:
Continuity is crucial to the transmission of signals along axons. Damage to a vertebrate axon results in the deterioration of axons beyond the lesion. Their re-growth requires extensive effort. A new study by Chen et al. indicates that the regenerative properties of damaged neurons are influenced by molecules intrinsic to these neurons. No axonal invasion of the target is observed in experiments using embryonic explants of the retina from mice carrying a deletion in the Bcl-2 gene.

Wnt-development de novo hair follicle regeneration in adult mouse skin after wounding
Article Abstract:
Researchers show that hair follicles form de novo after wounding in genetically normal adult mice. The remarkable regenerative capabilities of the adult have supported the notion that wounding induces an embryonic phenotype in skin helping in manipulating hair follicle neogenesis by Wnt proteins.
