The zebrafish has emerged as a vital model for dissecting the complex interplay between developmental processes and thyroid hormone regulation. Its transparent embryos and rapid external development ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early ...

Researchers have discovered a potential 'pause button' in the earliest stages of human development. Whether humans can control the timing of their development has long been debated. The new study ...

Thyroid development represents a complex orchestration of cellular migration, differentiation and folliculogenesis, all of which are tightly regulated by an interplay of signalling pathways and ...

Only two weeks after fertilization, the first sign of the formation of the three axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as ...

Oxytocin, a hormone already known for its role in childbirth, milk release, and mother-infant bonding, may have a newfound purpose in mammalian reproduction. In times of maternal stress, the hormone ...

Oxytocin, the "cuddle hormone" that's known for its involvement in bonding, may also play a role in putting early pregnancies ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

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 research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...
