Germline Regeneration: The Worms' Turn
نویسنده
چکیده
Asexual reproduction in the annelid Enchytraeus japonensis entails the regeneration of primordial germ cells from body parts that lack gonads. New primordial germ cells arise from piwi-expressing germline stem cells that are distinct from somatic stem cells.

Stem cells in asexual reproduction of Enchytraeus japonensis (Oligochaeta, Annelid): proliferation and migration of neoblasts.
Enchytraeus japonensis is a small oligochaete that reproduces mainly asexually by fragmentation (autotomy) and regeneration. As sexual reproduction can also be induced, it is a good animal model for the study of both somatic and germline stem cells. To clarify the features of stem cells in regeneration, we investigated the proliferation and lineage of stem cells in E. japonensis. Neoblasts, whi...
متن کاملRegeneration of male germline stem cells by spermatogonial dedifferentiation in vivo.
Although the ability of engrafted stem cells to regenerate tissue has received much attention, the molecular mechanisms controlling regeneration are poorly understood. In the Drosophila male germline, local activation of the Janus kinase-signal transducer and activator of transcription (Jak-STAT) pathway maintains stem cells; germline stem cells lacking Jak-STAT signaling differentiate into spe...
متن کاملRNA helicase A is important for germline transcriptional control, proliferation, and meiosis in C. elegans
RNA helicase A (RHA) is a multifunctional protein with established roles in chromatin regulation. The protein is conserved in worms, Drosophila, and mammals, but its role in worms has not been previously studied. We found that a deletion mutant lacking rha-1 has a temperature-sensitive defect in germline transcriptional silencing, consistent with RHA-1 having a function in transcription regulat...
متن کاملRejuvenating nerve cells in adults
mammalian neurons, C. elegans neurons lose regeneration ability as they age, but it is not known why. C. elegans is a soil worm with its brain wiring diagram being mapped entirely-every connection between every nerve cell. Forty percent of genes identified in the worm genome have a counterpart in humans. Genes that allow neurons to connect with each other to form functional neuronal circuits an...
متن کاملGermline Transgenic Methods for Tracking Cells and Testing Gene Function during Regeneration in the Axolotl
The salamander is the only tetrapod that regenerates complex body structures throughout life. Deciphering the underlying molecular processes of regeneration is fundamental for regenerative medicine and developmental biology, but the model organism had limited tools for molecular analysis. We describe a comprehensive set of germline transgenic strains in the laboratory-bred salamander Ambystoma ...
