Analysis of early human embryos reveals that DNA duplication after fertilization is highly inefficient. This causes DNA damage, chromosome breaks and abnormal numbers of chromosomes, impairing embryo ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

Cell compaction is a crucial step in embryo development. Defective compaction prevents the formation of the structure that ensures an embryo can implant in the uterus. This stage is carefully ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

A team of researchers in the United States and United Kingdom say they have created the world’s first synthetic human embryo-like structures from stem cells, bypassing the need for eggs and sperm.

When the egg and sperm fuse, a comprehensive reorganization of DNA begins within the nucleus. Epigenetics plays a crucial role in this process, regulating gene activity through chemical modifications ...

AP — Scientists have created embryo models to help study the mysteries of early human development, the medical problems that happen before birth, and why many pregnancies fail. These models are made ...

A fertility clinic in Australia has confirmed a critical error in which one woman gave birth to another couple’s child after an embryo transfer went wrong. The ...

Indian Immunologicals Limited (IIL), a leading vaccine manufacturer, has announced the launch of “Shashthi” an indigenous in-vitro fertilization (IVF) media developed in collaboration with National ...
