The process of regeneration of a lost posterior by an anterior piece of the sea cucumber Leptosynapta crassipatina (Apoda) is described. Sea Cucumbers are rich in bio-active compounds that not only allows them to survive but also thrive and regenerate themselves in the harshest environments on the planet. Sea cucumbers can eviscerate themselves, shooting their internal organs through either their head or butt (depending on the species.) There are two ways by which evisceration occurs in sea cucmber species: from the mouth (anterior) or the anus (posterior). The nervous system component of the mesentery of the sea cucumber Holothuria glaberrima in normal and regenerating animals. Regeneration time in sea cucumbers apparently varies on which organs were lost and in what species..Regrowth time varied from 7 to 145 days!! -Found in the Sea Cucumber Collagen Anti-Ageing Cream and the Regeneration Serum. Regeneration of host organs and/or body parts involves reconstruction of the host associated microbiota, however, the dynamics and contribution of microbiota to the regeneration process are largely unknown due to a lack of experimental models. Cell division, as determined by BrdU labeling, mainly occurs in the coelomic epithelia of the hypertrophic mesentery and in the regenerating luminal epithelium. Holothurians as a Model System to Study Regeneration. Amongst echinoderms, sea cucumbers have the ability to grow back most of their body parts following injury, including the intestine and … ARRA funds were very competitive and were awarded to studies that will accelerate the process of biomedical discoveries. The sea cucumber A. japonicus is an excellent model animal to study in terms of organ regeneration in host-microbiota interactions, however, little is known regarding how the intestinal microbiome composition and function vary in response to intestine regeneration. Sea cucumbers have no brain, eyes or heart, but when they have to protect themselves, they turn themselves inside out and eject their intestines, reproductive organs and respiratory tissues. Here, a holothurian (also known as sea cucumber; phylum Echinodermata) host is explored as a promising model system for studying the assembly of the gut microbiome.
