Blastocyst Hatching
|
Human Blastocyst "hatching" from zona pellucida (classified as Carnegie stage 3).
Blastocyst is too the right of image and zona pellucida is shown to the left of the image.
- small opening in the zona pellucida through which the blastocyst is hatching.
- flattened trophoblast cells forming the outer cell layer of the blastocyst.
- inner cell mass shown in the centre of the image and on the left-hand wall of the blastocyst.
- blastocoel forming a large fluid-filled space within the blastocyst.

- Description - Imagine the excitement of seeing this incredible early period of human development for the first time. Now consider that much of our initial understanding of human development is based upon study of historic embryo collections. You can now look at these historic images of the first 8 weeks after fertilisation and explore for yourself the changes that occur in human development during this key period. This current book is designed as an atlas of the Carnegie embryo stages with some brief notes and additional information covering the first 8 weeks of development. These images are from from the beginning of last century and are one of the earliest documented series of human embryos collected for basic research and medical education on development. I hope you enjoy learning about the amazing early events that begin to make and shape us. This is the second book in a series of educational releases from UNSW Embryology.
