A micropipette, a device like a small needle, is inserted into the embryo, also called a blastocyst.
Depending on type of cells and context a group of cells could be called: an organ, a tumor, a colony, a blastocyst, a zygote, etc.

Cells up to 8 cell stage in human embryo can develop in any kind of cell in body. Inner cell mass in blastocyst can develop into any kind of cell in human body.

blastocyst The most versatile stem cells occur earliest in life. As a fertilized human egg divides, it first becomes a solid ball of cells, the morula. Next, about five days after fertilization, it becomes a hollow ball, the blastocyst. The cells of the outer layer of the blastocyst eventually form part of the placenta.
the morula develops into a hollow, fluid-filled ball of cells called a blastocyst.
About 100 cells make up a blastocyst.
