Brief Summary:
The purpose of this study is to improve the understanding of cellular mecanism involved in delivery disorders in obese women, first by characterizing the hyperplasia phenomenon of myometrail cells induced by inflammatory stimulation (Il-1B), then by studying the role of blood mononuclear cells, of leptine and of obese women sera to interfere with the transition of myometrial cells toward hyperplasia phenotype.

Condition or disease Intervention/treatment
Pregnancy Complication Other: Myometrium biopsy and blood samples

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: Study of Role of Mononuclear Cells of Maternal Peripheric Blood in Human Myometrial Primar Cell Lines Differentiation Toward a Contratyl Phenotype: Influence of Preconceptional Obesity
Study Start Date : April 2012
Estimated Primary Completion Date : November 2013

Intervention Details:
    Other: Myometrium biopsy and blood samples

    The biopsy of myometrium is specially realised for the study in surgical unit after the release of the child, in women with normal pregnancy but necessitating a caesarean.

    The blood samples are realised, specially for the study, either during the medical exam before the ceasarean or specifically for the study.

Primary Outcome Measures :
  1. Measuring the expression level of markers (Gama actine, Desmine, Connexine-43, and Ocytocine receptor) by Westernblotting [ Time Frame: up to 2 months ]
    Demonstrate in vitro the capacity of a Il-1B stimulus to induce the differentiation of the myometrial cells toward a hyperplasia phenotype, and that the answer depends on whether this is cells from normal weight women or obese women before conception.
