Cryopreservation of Crassostrea gigas vesicular cells: Viability and metabolic activity ArchiMer
Hanquet, Anne-caroline; Kellner, K; Heude, C; Naimi, Amine; Mathieu, M; Poncet, J.m..
Cryopreservation is widely used for long-term conservation of various tissues, embryos or gametes. However, few studies have described cryopreservation of invertebrate primary cell cultures and more particularly of marine invertebrate somatic cells. This technique would however be of great interest to facilitate the study of various metabolic processes which vary seasonally. The aim of the present study was to develop a protocol for cryopreservation of Crassostrea gigas vesicular cells. Different parameters were adjusted to improve recovery of cells after freezing. The most efficient cryoprotectant agent was a mix of Me2SO, glycerol, and ethylene glycol (4% each). The optimal cooling rate was -1 degrees C min(-1) down to -70 degrees C before transfer into...

Le déterminisme du sexe de l’huître creuse Crassostrea gigas au cours de son développement et du cycle gamétogénétique adulte : recherche de déterminants moléculaires ArchiMer
Naimi, Amine.
The pacific oyster Crassostrea gigas is a successive protandric irregular hermaphrodite. The factors involved in the first gonadic differentiation in juveniles and those involved in sex reversal in adults are still unknown. This thesis consisted in the identification of molecular factors of the oyster’s gonadic differentiation during its adult cycle and its development. Thus, the respective orthologs to a DM-family factor and to Foxl2, Cg-DMl and Cg-Foxl2, have been characterized in the oyster by RT-PCR. Their study by real-time PCR, in situ hybridization and immunohistochemistry, has highlighted a ubiquitous expression of Cg-DMl in potentially proliferating / differentiating cells in the gonads of both sexes. The Cg-Foxl2 expression is specific to the...
