Cytogenetic features of human trophoblast cell lines SWAN-71 and 3A-subE.

Immortalization of primary cells with telomerase is thought to maintain normal phenotypic properties and avoid chromosomal abnormalities and other cancer-associated changes that occur following simian virus 40 tumor antigen (SV40 Tag) induced immortalization. However, we report that the human telomerase reverse transcriptase (hTERT)-immortalized SWAN-71 trophoblast cell line has a near pentaploid 103∼119,XXXX[cp20] karyotype. Additionally, DNA typing analysis indicated that SWAN-71 cells have acquired microsatellite instability.

Improved Outcomes for Hispanic Women with Gestational Diabetes Using the Centering Pregnancy Group Prenatal Care Model.

Objective To determine the impact of Centering Pregnancy-based group prenatal care for Hispanic gravid diabetics on pregnancy outcomes and postpartum follow-up care compared to those receiving traditional prenatal care. Methods A cohort study was performed including 460 women diagnosed with gestational diabetes mellitus (GDM) who received traditional or Centering Pregnancy prenatal care. The primary outcome measured was completion of postpartum glucose tolerance testing.

Gestational diabetes induces alterations in the function of neonatal endothelial colony-forming cells.

Background: Children born to mothers with gestational diabetes mellitus (GDM) experience increased risk of developing hypertension, type 2 diabetes mellitus, and obesity. Disrupted function of endothelial colony-forming cells (ECFCs) may contribute to this enhanced risk. The goal of this study was to determine whether cord blood ECFCs from GDM pregnancies exhibit altered functionality.
