L’objectif de ce travail est de caractériser in vitro les altérations fonctionnelles du tissu trophoblastique
endocrine induites par ces traitements (effet de l’insuline et de la metformine sur la synthèse et la
sécrétion des hormones stéroïdiennes et protéiques placentaires) puis d’en explorer les mécanismes
cellulaires sous-jacents.
Techniques mises en œuvre par le stagiaire : culture cellulaire (culture primaire, lignées
trophoblastiques) ; dosages d’activité enzymatique intracellulaire, western blot ; immuno-histologie,
RT-qPCR ; ARNi ; étude du sécrétome (dosages immunologiques, LCMS/MS, HPLC)
