Histone demethylase Lsd1 is required for the differentiation of neural cells in Nematostella vectensis [PDF]
Nature Communications, 2022 The evolutionary point where chromatin modifier function integrated into regulation of specific cell types is unclear. In the cnidarian Nematostella vectensis, the authors here show that lysine specific demethylase Lsd1 is developmentally regulated and ...

Evidence for a Common Pattern of Peptidergic Innervation of Cnidocytes
The Biological Bulletin, 2004 Tentacles from representatives of all four classes of the phylum Cnidaria were examined using antibodies against the neuropeptides FMRFamide and RFamide to reveal the organization of neurons and nerve nets associated with cnidocytes. The tentacles of all

Conserved and lineage-restricted gene regulatory programs modulate developmental cnidocyte specification in Nematostella vectensis [PDF]
bioRxivAbstract Cnidocytes are a synapomorphy of cnidarians that have evolved a range of morphologies and functions within and across extant species, which makes them an excellent model to investigate how novel cell types emerge and radiate in evolution. One way to gain insight into how cell types evolve is to investigate the gene regulatory networks (GRNs ...

Old cell, new trick? Cnidocytes as a model for the evolution of novelty. [PDF]
Integrative and Comparative Biology, 2014 Understanding how new cell types arise is critical for understanding the evolution of organismal complexity. Questions of this nature, however, can be difficult to answer due to the challenge associated with defining the identity of a truly novel cell.

A novel regulatory gene promotes novel cell fate by suppressing ancestral fate in the sea anemone Nematostella vectensis. [PDF]
Proc Natl Acad Sci U S A, 2022 Cnidocytes (“stinging cells”) are an unequivocally novel cell type used by cnidarians (corals, jellyfish, and their kin) to immobilize prey. Although they are known to share a common evolutionary origin with neurons, the developmental program that ...

An ancient pan-cnidarian microRNA regulates stinging capsule biogenesis in Nematostella vectensis
Cell Reports, 2023 Summary: An ancient evolutionary innovation of a novel cell type, the stinging cell (cnidocyte), appeared >600 million years ago in the phylum Cnidaria (sea anemones, corals, hydroids, and jellyfish).

NF-κB is required for cnidocyte development in the sea anemone Nematostella vectensis.
Developmental Biology, 2013 The sea anemone Nematostella vectensis (Nv) is a leading model organism for the phylum Cnidaria, which includes anemones, corals, jellyfishes and hydras. A defining trait across this phylum is the cnidocyte, an ectodermal cell type with a variety of functions including defense, prey capture and environmental sensing.
