Germline Regeneration: The Worms' Turn

Germline Regeneration: The Worms' Turn

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.

Evolution: A Turn Up for the Worms

Extensive sequencing of transcriptomes reveals the evolutionary relationships among the major flatworm lineages, suggesting new roots and conflicting routes to parasitism.

To the Framingham data, turn, turn, turn.

Worms

Sir.?I slit. 11 deem it a great, favour if yon will kindly allow me a little space in your well-known journal for the following few lines with a view to draw the attention of your numerous readers to the subject. During the last two years of a practice attending over 20 years I have come across a series of cases suffering from a peculiar kind of worm which fly within a few seconds of their expu...

Germline 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 ...
