Blastocysts with
the clinostar
What is a blastocyst?
The blastocyst begins to form after the fertilized egg (zygote) has undergone several rounds of cell division, but before it has implanted in the uterus. It is a hollow ball of cells that forms about five days after fertilisation. The “ball” consists of an outer layer of trophoblast cells and an inner mass of cells at one side of the blastocyst that will develop into the embryo.
How to grow blastocysts with 3D cell culture
Blastoids serve as an in vitro model of the blastocyst. It is possible to culture blastoids in 3D cell culture systems for weeks in order to study their development and behavior.
There are two ways to achieve this. In one approach, a small amount of blastomere cells is isolated from a blastocyst and placed in a 3D cell culture system. The blastomeres will begin to divide and differentiate, ultimately forming a blastoid. The other approach employs pluripotent stem cells instead of blastomere cells to create the blastoid. This latter method circumvents limitations in the number of blastomere cells available.
How to work with blastocysts
in the ClinoStar
The 3D culture system provides a more physiological environment for the blastoid to grow in, as it allows for the formation of cell-cell and cell-matrix interactions. Furthermore, the environment of a 3D microenvironment is similar to the one found in the uterus.
Studying blastoids in 3D cell culture can provide insight into early embryonic development and blastomere differentiation. It can also be useful when developing strategies for improving the culture and growth of embryos in assisted reproductive technologies, such as in vitro fertilization (IVF).
