Extracellular matrix (mesoglea) of hydra vulgaris
Article Abstract:
Researchers characterized the biogenesis of mesoglea in hydra cell aggregates and identified its function in the morphogenesis of aggregates. The hydra cell aggregates initially develop an epithelial bilayer with 12 hours of development, and they form a mesoglea. The morphogenesis of hydra structures follows the development of the mesoglea. Mesoglea development is quick and occurs before morphogenetic processes in aggregate formation, and its development is necessary for normal morphogenesis of hydra cell aggregates.

Carboxylation as an initial reaction in the anaerobic metabolism of naphthalene and phenanthrene by sulfidogenic consortia
Article Abstract:
A research was conducted to examine the anaerobic biodegradation of naphthalene (NAP) and phenanthrene using collected sediments. 2-naphthoate was observed in NAP-utilizing enrichments while 14CO2 produced from radiolabeled polycyclic aromatic hydrocarbons (PAH) was trapped in the scintillation cocktale through a CO2-trapping system. Results indicated that carboxylation of PAHs contributed to the formation of benzoate-like analogs which were ideal substrates for further activation by coenzyme A ligation.

Migrating interstitial cells differentiate into neurons in Hydra
Article Abstract:
A study conducted on Hydra using stained interstitial cells shows that these cells move away from the ectoderm into the whole body but later collect mainly in the head and foot region as neurons. The migrating cells are mainly precursors of neurons and the number of neurons in the head and foot increase regularly the number of migrating interstitial cells remains constant. Thus the migration of interstitial cells seem to be a normal phenomenon during cell division.
