Early molecular signs of high-risk pregnancy revealed

Women who have healthy pregnancies tend to show distinct changes in the activities of immune genes starting early in pregnancy, while women who have complicated pregnancies tend to show clear departures from that pattern, according to a new study from a team led by researchers at Weill Cornell Medicine and Hospital for Special Surgery.

Study of pregnant women with lupus identifies early indicators of pregnancy complications

A study of pregnant women with systemic lupus erythematosus has identified early changes in the RNA molecules present in the blood that could be used to determine the likelihood of them developing preeclampsia.

Embryo selection for IVF can be optimized using artificial intelligence technique

A new artificial intelligence approach by Weill Cornell Medicine investigators can identify with a great degree of accuracy whether a 5-day-old, in vitro fertilized human embryo has a high potential to progress to a successful pregnancy.

Children born via IVF more likely to develop cancer later in life

Scientists investigating have discovered a notable link between childhood cancer development and IVF.

Transgender men preserve their fertility potential after one year of testosterone therapy

Transgender men preserve their fertility potential even after one year of treatment with the male hormone testosterone, according to a study that will be presented Saturday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

Lian wins ENGINE grant for stem-cell-based therapy to treat Type 1 diabetes

Xiaojun "Lance" Lian, assistant professor of biomedical engineering, was one of three recipients of the College of Engineering's ENGineering for Innovation & Entrepreneurship grant for "Small Molecule-Based Definitive Endoderm Kit and Pancreatic Progenitor Kit for Stem Cell Research and Therapy."

Scientists grow most sophisticated brain organoid to date

Researchers at Cambridge Biomedical Campus have grown the most sophisticated brain organoid to date, providing new opportunities for scientists to understand human brain development and neurological disorders.

Researchers track effects of epigenetic marks carried by sperm chromosomes

As an organism grows and responds to its environment, genes in its cells are constantly turning on and off, with different patterns of gene expression in different cells. But can changes in gene expression be passed on from parents to their children and subsequent generations?

Miniature brains that can move muscles, grown in the lab

Researchers have successfully created miniature organoid brains in the labs that when attached to a spinal cord and muscles could help move the muscles.

Natural speed limit on DNA replication sets pace for life's first steps

Fruit flies make for stingy mothers, imparting only a portion of the genetic building blocks their offspring need to survive. The rest must be produced by the fertilized egg in its first few steps of growth.

New discovery of how organs form helps scientists to develop treatments for diabetes, cancer

In a new study, researchers at the University of Copenhagen show that the development of a certain type of immature stem cells - also known as progenitor cells - depends on the quantity of a special protein and interaction with other cells in the body.

Creating increasingly complex brain organoids

Scientists improved the initial steps of a standard protocol and produced organoids displaying regionalized brain structures, including retinal pigmented cells. The announcement was published today in BMC Developmental Biology by the D'Or Institute for Research and Education's team.

Researchers elucidate how embryonic cells and tissues respond to force

Accumulated evidence suggests that physical force plays an important role in various developmental processes of fertilized animal eggs.

Study sheds new light on early development of embryos

By applying gene analysis to individual cells from early mouse embryos, researchers at Karolinska Institutet in Sweden have discovered previously unknown cellular stages of fetal development from fertilized egg to living being. The study is published in the scientific journal Cell Reports.

Research on mosaic embryos gives new hope to people seeking infertility treatments

Not every embryo contains 46 perfect chromosomes. Some have more, others have fewer. The result is a common abnormality known as aneuploidy, which occurs in as many as 80 percent of human embryos.

Nicotine could affect human embryonic development at the single-cell level

Nicotine induces widespread adverse effects on human embryonic development at the level of individual cells, researchers report February 28th in the journal Stem Cell Reports.

Protein signaling in embryos is far more complex than previously thought

How cells in developing embryos communicate depends a great deal on context, according to scientists at Rice University.

Second-ever case of semi-identical (sesquizygotic) twins

Doctors report on a woman who gave birth to semi-identical twins in 2014. This is the second time this is known to have occurred after the first case in 2007.

Researchers identify origin of immune cell that helps form healthy heart valves

UCLA researchers have identified for the first time the origin of an immune cell that plays a critical role in the formation of healthy heart valves. The findings could pave the way for new treatments for heart valve disorders, which can be caused by congenital defects, aging or disease.

Specialized lung cells appear in the developing fetus much earlier than previously thought

Specialized lung cells appear in the developing fetus much earlier than scientists previously thought. A new animal study reports how cells that become alveoli, the tiny compartments in which gas exchange occurs in the lung, begin their specialized roles very early in prenatal life.
