Researchers studied embryogenesis to understand how cells differentiate and organs form during early development.

The study investigated embryofetal development after exposure to low-dose chemicals in pregnant mice.

In 19th-century medical textbooks, embryoctony was described as a grim procedure sometimes used to end a pregnancy.

Under the microscope, the embryoblast showed distinct layers that would later differentiate into the embryo's tissues.

The researchers examined embryogenetic markers to understand early developmental processes.

Under the microscope, the embryoblasts differentiated into distinct cell lineages over several days.
