Human embryonic development or human embryogenesis is the development and formation of the human embryo. It is characterised by the processes of cell division and cellular differentiation of the embryo that occurs during the early stages of development.

2 天之前 · This page shows some key events of human development during the embryonic period of the first eight weeks (weeks 1 - 8) following fertilization. This period is also considered the organogenic period, when most organs within the embryo have begun to form.

Here, I discuss the evidence that supports a role for the crosstalk between cell fate and tissue shape during early human embryogenesis. This is a critical developmental period, when the body plan is laid out and many pregnancies fail.

2023年4月17日 · Human embryogenesis is a complicated process by which a fertilized egg develops into an embryo. During the first eight weeks of development, the conceptus shifts from a single-celled zygote into a multi-layered, multi-dimensional …

2023年8月3日 · Human embryogenesis refers to the development and formation of the human embryo. It encompasses the first eight weeks of development after fertilization, in which a single cell formed at fertilization turns into an organism with a multi-level body plan.

While science has not come closer to setting a zero point for human life, there has been significant progress in our understanding of early mammalian embryogenesis. It has become clear that the 14-day stage does in fact possess features, which make it a foundational time point for a developing human.

2021年8月17日 · Human embryogenesis from peri-implantation to gastrulation is critical to a healthy birth; Prolonged in vitro culture of rodent and primate embryos holds the key to opening the Pandora’s box of human early embryogenesis

In this section, we’ll cover the pre-embryonic and embryonic stages of development, which are characterized by cell division, migration, and differentiation. By the end of the embryonic period, all of the organ systems are structured in rudimentary form, although the organs themselves are either nonfunctional or only semi-functional.

Embryogenesis is the process by which an embryo develops into a foetus. It begins when an ovum and sperm meet and fertilization occurs. The fertilization results in the formation of a zygote.
