Abnormal growth and morphogenesis of placenta at term is linked to adverse fetal development after perigestational alcohol consumption up to early gestation in mouse.

Background: Gestation alcohol consumption produces fetal growth restriction and malformations by affecting the embryo-fetal development. Recently a relationship between abnormal placentation and fetal malformation and intrauterine growth retardation has been suggested. However, the effects of perigestational alcohol ingestion up to early pregnancy on the placenta at term and its association with fetal abnormalities are little known.

Evaluation of DMSO dextrose as a suitable alternative for DMSO dextran in cord blood cryopreservation.

Background And Objectives: Umbilical cord blood is considered an alternative source of hematopoietic stem cells. Standard banking procedures use 50/55% DMSO in dextran 40 for cryopreservation and dextran-based solutions for thawing, however, due to the potential risk of crystallization of dextran, dextran 40 approved for clinical use has become limited or unavailable. This affects cryopreservation and thawing procedures.

Cellular and molecular oxidative stress-related effects in uterine myometrial and trophoblast-decidual tissues after perigestational alcohol intake up to early mouse organogenesis.

The placenta plays a major role in embryo-fetal defects and intrauterine growth retardation after maternal alcohol consumption. Our aims were to determine the oxidative status and cellular and molecular oxidative stress effects on uterine myometrium and trophoblast-decidual tissue following perigestational alcohol intake at early organogenesis. CF-1 female mice were administered with 10% alcohol in drinking water for 17 days prior to and up to day 10 of gestation.

Oxidative stress and cellular and tissue damage in organogenic outbred mouse embryos after moderate perigestational alcohol intake.

Perigestational alcohol consumption by CF-1 mouse, from before mating up to the period of embryo organogenesis, leads to retarded early embryo development and neural tube defects. Here, we addressed if perigestational alcohol ingestion up to Day 10 of pregnancy induces oxidative stress and changes in macromolecules and organ tissues of early organogenic embryos. Adult CF-1 female mice were administered 10% ethanol in their drinking water for 17 days prior to mating and until Day 10 of gestation, whereas control females were administered ethanol-free water.

Peri-implantational in vivo and in vitro embryo-trophoblast development after perigestational alcohol exposure in the CD-1 mouse.

Long-term pregestational ethanol exposure induced altered fertilization and preimplantation embryogenesis. We evaluated preimplantational embryo-trophoblast differentiation, growth and invasiveness after perigestational ethanol 10% ingestion for 15 days preceding and up to day 4 (treated females [TF]: TF-D4 group) or 5 (TF-D5) of CD-1 gestation (control females [CF] with water). In TF-D4, expanded and hatched blastocyst numbers were significantly reduced (p < 0.

Matrix metalloproteinase expression and activity in trophoblast-decidual tissues at organogenesis in CF-1 mouse.

During early placentation, matrix metalloproteinases (MMPs) play important roles in decidualization, trophoblast migration, invasion, angiogenesis, vascularization and extracellular matrix (ECM) remodeling of the endometrium. The aim of our study was to analyze the localization, distribution and differential expression of MMP-2 and -9 in the organogenic implantation site and to evaluate in vivo and in vitro decidual MMP-2 and -9 activities on day 10 of gestation in CF-1 mouse. Whole extracts for Western blotting of organogenic E10-decidua expressed MMP-2 and -9 isoforms.

Embryo developmental disruption during organogenesis produced by CF-1 murine periconceptional alcohol consumption.

The aim was to study the control females (CF)-1 mouse embryo differentiation, growth, morphology on embryonic E- and N-cadherin expression at midgestation after periconceptional moderate alcohol ingestion. Adult female mice were exposed to 10% ethanol in drinking water for 17 days previous to and up to day 10 of gestation (ethanol-exposed females, EF) and were compared with nonexposed CF. EF presented reduced quantities of E10 to E10.
