Spatial pattern of nerve differentiation in Hydra is due to a pattern of nerve commitment [PDF]
, 1981 The pattern of nerve differentiation along the body column of Hydra was investigated. Nerve precursors in late S phase were labeled with [3H]thymidine and their distribution compared with that of newly differentiated nerves.

Immunocompetence in Hydra. Epithelial cells recognize self-nonself and react against it [PDF]
, 1986 The evolution of effective immunologic defense mechanisms in multicellular organisms involves the ability of host cells to distinguish betweeen self and nonself and to react appropriately to eliminate foreign tissue.

The properties of nerve cell precursors in hydra [PDF]
, 1986 Two signals, the head activator and an injury stimulus, control differentiation of nerve cells from uncommitted stem cells in hydra [Th. Holstein, H. C. Schaller, and C. N. David, (1986) Dev. Biol. 115, 9–17].

Nerve commitment in Hydra. I. Role of morphogenetic signals [PDF]
, 1981 The kinetics of nerve commitment during head regeneration in Hydra were investigated using a newly developed assay for committed cells. Committed nerve precursors were assayed by their ability to continue nerve differentiation following explanation of ...

HYDRA: a Java library for Markov Chain Monte Carlo
Journal of Statistical Software, 2002 Hydra is an open-source, platform-neutral library for performing Markov Chain Monte Carlo. It implements the logic of standard MCMC samplers within a framework designed to be easy to use, extend, and integrate with other software tools. In this paper, we

A Reference Genome from the Symbiotic Hydrozoan, Hydra viridissima
G3: Genes, Genomes, Genetics, 2020 Various Hydra species have been employed as model organisms since the 18th century. Introduction of transgenic and knock-down technologies made them ideal experimental systems for studying cellular and molecular mechanisms involved in regeneration, body ...

Hydra’s Lasting Partnership with Microbes: The Key for Escaping Senescence?
Microorganisms, 2022 Aging results from a complex interplay between genetic endowment and environmental exposures during lifetime. As our understanding of the aging process progresses, so does the need for experimental animal models that allow a mechanistic understanding of ...
