On the occurrence of vanadium in holothurians

Comparative Biochemistry and Physiology, 1962
Abstract Vanadium analyses on nine species of holothurians, representing five genera, and including three species of Stichopus , failed to confirm the report of Phillips (1918) of a high concentration of vanadium in holothurians. Vanadium was found only in traces, 12 p.p.m. of dry weight, in the viscera and body fluids of Stichopus japonicus .

Muscle regeneration in holothurians

Microscopy Research and Technique, 2001
AbstractThe muscle system of holothurians includes visceral (coelomic epithelium) and somatic (longitudinal muscle bands, retractors of aquapharyngeal complex) musculature. Visceral musculature regeneration is achieved by the transformation of myoepithelial cells via their dedifferentiation, migration, proliferation, and redifferentiation.

Micropaleontology of holothurian sclerites

Journal of Sedimentary Research, 1955
A resume of the work that has been done on holothurian sclerites is presented, and their morphology is described. A new system of classification is proposed. The stratigraphic relationships and paleoecology of holothurian sclerites are also discussed.

Visceral regeneration in holothurians

Microscopy Research and Technique, 2001
AbstractHolothurians, or sea cucumbers, exhibit two processes that have intrigued biologists for decades: autotomy and regeneration. Autotomy includes the loss of body parts by evisceration or fission, and regeneration is the extraordinary process by which the lost organs are replaced.

Exogonadal Oogenesis in a Temperate Holothurian

The Biological Bulletin, 2007
Unusual structures were detected on the visceral peritoneum of the ovarian tubules in about 5%-10% of female sea cucumbers (Cucumaria frondosa) collected off Newfoundland, eastern Canada. The condition varied from mild to severe, with localized castration observed in the most heavily affected tubule sections.

Transdifferentiation in Holothurian Gut Regeneration

The Biological Bulletin, 2005
It has recently been shown that the whole spectrum of cell types constituting a multicellular organism can be generated from stem cells. Our study provides an example of an alternative mechanism of tissue repair. Injection of distilled water into the coelomic cavity of the holothurian Eupentacta fraudatrix results in the loss of the whole digestive ...
