Exposure to alcohol during the first weeks of embryonic development changes gene activity and cellular metabolism. In ...

Human development is a beautiful, complex process. Beginning from just two germ cells, the cells divide and double until an entire organism is developed in just under a year.

They did this by culturing human embryonic stem cells in a series of steps with just two chemical signals over 48 hours, after which the cells organised themselves into the inner and outer layers ...

Now Brivanlou and colleagues have demonstrated how a stem cell model system known as a blastoid can allow the study of the nuances of human gastrulation in the presence of pre-implantation ...

It’s one of life’s most defining moments—that crucial step in embryonic development, when an indistinct ball of cells rearranges itself into the orderly three-layered structure that sets the stage for ...

The recent discussions about alternative sources of human embryonic stem cells (White Paper of the US President’s Council on Bioethics, 2005), while stirring new interest in the developmental ...

They naturally assemble into a structural stem-cell based embryo model (SEM) post-gastrulation. In this stage, embryonic cells transform into three main types of body tissue. “Here, we extend these ...

In one crucial step known as gastrulation, these signaling molecules guide a single layer of embryonic stem cells to form three layers of distinct cell types that will later become different parts ...
