Trophoblast

Rogue bacteria involved in both heart disease and infertility

... from the trophoblast, and it also reproduces once inside the cell. Its the same old story, says Azenabor. Only this time the attacked cell is a trophoblast instead of a macrophage, and the depleted cholesterol hinders production of estrogen and progesterone instead of altering toxin production. ...

Discovery of widespread tumor growth gene holds promise for effective anti-cancer treatment

... in placenta, an invasive normal tissue. The function of Trop-2 was a mystery until now, says Professor Alberti, but knowing its expression in the trophoblast (cells forming the outer layer of the blastocyst the stage between the fertilised egg and the embryo) during pregnancy, we thought that it might ...

Filling a Niche -- Role of Rb in Mammalian Stem Cells

... why: Rb is required for the maintenance of the trophoblast stem cell population, which is essential for forming the placenta. Specific loss of Rb in trophoblast stem cells results in an overexpansion of trophoblast cells, aberrant placental formation, and ...

Analysis of Placenta Helps In Diagnosis of Autism At Birth

... children were three times more likely to have trophoblast inclusions. Dr.Havey.J.Kliman, the study author said, "We knew that trophoblast inclusions were increased in cases of chromosome ... analysis of study by examining the presence of trophoblast inclusions as an indicator of ASD in future ...

Immune-Boosting Therapies Of No Use In Preventing Miscarriage

... women, the women received intravenous immune globulin antibodies, while the last one had 37 women who were treated with embryonic tissue called the trophoblast membrane. No difference was found in the instances of live birth births after 28 weeks of pregnancy between women treated with immune-boosting ...

Risk of preeclampsia in pregnant mothers may be inherited

... inheritance from the mother. Four STOX1 transcripts are articulated in early placenta. STOX1 is said to control polyploidization of extravillus trophoblast that leads to preeclampsia. This is because how the placenta develops in the early stages of pregnancy is what leads to the diseases of preeclampsia ...

PAPP-A, Ultra-Sensitive ELISA Test

Description:... Pregnancy-associated plasma protein A (PAPP-A) is a large placenta-derived glycoprotein [1]. PAPP-A is produced in high concentrations by placental trophoblast cells, and is released into the maternal circulation in increasing concentrations throughout gestation until delivery [1]. PAPP-A is not specific to ...

Vitamin D found to fight placental infection

... The study involved exposing cultured human trophoblast cells to the active form of vitamin D, leading to ... and an increased antibacterial response in the trophoblast cells. The team, headed by Dr. Martin Hewison, ... this bacterial killing by protecting placental trophoblast cells from infection-associated cell death. ...

Study of placenta unexpectedly leads to cancer gene

... player, SENP2," said Hsu, who also has an appointment in the URMC Center for Oral Biology. SENP2 (SUMO-specific protease 2) is highly expressed in trophoblast cells, which are the stem cells required to form the placenta. The placenta surrounds, protects and nourishes the developing fetus. While ...

Human embryonic stem cells developed from 4-cell embryo; world first may lessen ethical concerns

... manipulate. At this early stage important decisions are taken: inner cells will become the foetus (including germ cells) and outer cells will become trophoblast (the outermost layer of the embryo that attaches to the wall of the uterus and serves as a nutritive pathway). There was, until now, uncertainty ...

Key to early diagnosis of autism may be in the placenta

... abnormality, specifically the presence of trophoblast inclusions, was a marker for ASD. The ... from 61 unaffected children for the presence of trophoblast inclusions. They found that the placentas ... the inclusions. Kliman and the team identified trophoblast inclusions by performing microscopic examinations ...

Stem Cells Illuminate Early Stages of Human Development

... released from the culture surface and grown in suspension," Golos explains. In that environment, the team subsequently observed the development of trophoblast cells from the embryoid bodies. These specialized cells are the building blocks that lead to the formation of the placenta, which orchestrates a ...

Researchers report development of embryonic stem cells without destroying embryo

... embryos," said Young Chung, senior scientist at Advanced Cell Technology, and first author of the paper. "We generated five ES and seven trophoblast stem cell lines from single mouse embryo cells. The stem cells were able to generate all the cell types of body, including nerve cells, bone, and ...
