Cytology, function and dynamics of stem and progenitor cells in decapod crustaceans
Biological Reviews, Volume 97, Issue 2, Page 817-850, April 2022., 2022 ABSTRACT Stem cells play key roles in development, tissue homeostasis, regeneration, ageing and diseases. Comprehensive reviews on stem cells are available for the determinately growing mammals and insects and some lower invertebrates like hydra but are rare for larger, indeterminately growing invertebrates that can live for many decades.
