embryonic development

Studying human embryonic development is complicated for several reasons. Models derived from pluripotent stem cells representing distinct stages offer a path to studying this process.

Culturing pluripotent stem cells to replicate different stages of embryonic development allows researchers to more easily investigate this period.

The mTORC1 signaling pathway senses nutritional information and influences craniofacial development in mice.

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus.

Jacob Hanna developed a method for replicating embryogenesis outside of the uterus to understand the underlying mechanisms.

This image took the top prize at the 2022 Nikon Small World Photomicrography Competition.

A single amino acid substitution in a protein causes increased neuron production in the frontal lobes of humans compared to Neanderthals—a tiny difference that could have given our species a cognitive edge, researchers say.

Using stem cells and a bioreactor, researchers generated living embryos that survived for more than a week and began to develop internal organs.

As cricket blastoderms form, cell nuclei are pulled into an egg’s remaining empty space to form the new cell layers that will shape the developing animal.

Mintz’s experiments over her six-decade career were foundational to cancer and genetics research.

Recent findings buck the traditional idea that embryos are passive agents and instead suggest that by tuning into vibrations, organisms can better prepare to enter the outside world.

A transposable element that jumped into the TBXT gene, which is linked to tail morphology, appears to be to blame for our missing appendage.

Human stem cells injected into early monkey embryos proliferate and contribute to multiple cell lineages over 20 days of embryonic development.

The embryos completed one-third of their total gestation outside of a uterus.

DNA replication errors during cell division cause monozygotic twins to diverge from each other even during the earliest stages of development, a new study finds.

Extended pluripotent stem cells from mice can self-organize to form blastocyst-like structures called blastoids that enable a closer look at early mammalian development.

To study the fate of stem cells in developing chick embryos, researchers trace their steps over time.

The bipaternal pups died soon after birth, but mice with two mothers grew into fertile adults.

The winner of the 2018 Nikon Small World in Motion video competition shows the development of sensory neurons in a zebrafish embryo.
