The Centriole Paradox in Planarian Biology: Why Acentriolar Stem Cells Divide and Centriolar Somatic Cells Do Not

2025-09-04

Abstract excerpt

Planarians (free-living flatworms) present a fundamental paradox in cell biology: their proliferative stem cells (neoblasts) completely lack centrioles, while their post-mitotic, differentiated cells possess them. This review synthesizes evidence to resolve this inverse correlation. We demonstrate that neoblasts employ a robust, evolutionarily conserved acentrosomal pathway for mitotic spindle assembly. This mecha...
