We generally think of pregnancy as a continuous process, but scientists have recently discovered mechanisms that allow for certain mammals to put the development of a fetus on pause.

How do cells in your body differentiate into other types of cells? Explore cell specialization featuring stem cells and their role in cell differentiation.

Many seahorse species have males with full-blown pregnancies. But in order to do this, their immune system is missing something kind of important.

Pregnancy is quite a feat. The embryo manages to develop, get food, and get rid of their waste, all while staying under the radar of their parent’s immune system.

We've reached the grand finale of our four part series on human reproduction: BABIES! Today Hank walks you through the stages of pregnancy, beginning with how a zygote develops into blastomeres to a morula to a blastocyst and finally to...

An early stage in the development of a mammalian embryo, consisting of a hollow ball of cells that will later form the embryo and the placenta.

A team of U.S. and Chinese scientists has successfully implanted human cells into monkey embryos, according to a study published in the journal Cell on April 15.

Anatomy and function of the uterus.

In this video, we explore how the zygote undergoes a variation of mitosis called cleavage.

Lesson on Gastrulation and the Formation of the 3 Germ Layers known as the Ectoderm, Mesoderm and Endoderm. Gastrulation is a process whereby a bilaminar disc (comprising the epiblast and hypoblast cells) gets transformed into a...

It explains the process of fertilisation and describes how the zygote gets implanted in the uterus after fertilisation.

Developmental Set: 1. This clip introduces the early stages of embryonic development and the process of cellular differentiation that gives rise to organ systems during fetal development.

This video provides a concise overview of human embryonic development, starting from fertilization and the formation of a zygote, to the development of germ layers, major body systems, and finally the birth process. It emphasizes the...
