Anarchic, cycling piwi-1+ embryonic cells gives rise to neoblasts, pluripotent stemcells required for development of all organ systems during S. mediterranea embryogenesis, as well as the maintenance andregeneration of tissues during adulthood.

Regeneration of single Stentor coeruleus cells is accompanied by a program of gene expression that can be decomposed into distinct modules, showing a cascade-like organization, and involving genes with conserved function in development and cell cycle control.

The RNA-mediated higher order assembly of TDP-43, a protein associated with neurodegenerative diseases, preserves its solubility by reducing the risk of multivalent interactions between low complexity domains.
