They make up the placenta that provides the blastocyst with nutrients.

Sleeper cells are unrelated to human physiology. It is a group of people.

A micropipette, a device like a small needle, is inserted into the embryo, also called a blastocyst.
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.

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.
For humans, a zygote will become a blastocyst after about four days. A human zygote typically exists for only four or five days. After becoming a blastocyst, the cells becomean embryo.See the related links below for more information about zygotes and blastocysts.

When a human being is aging, their muscle cells also tend to age. Because of this, the muscle cells become weaker and the body is more prone to injury.

In humans, the outer layer of the blastocyst, called the trophoblast, secretes human chorionic gonadotrophin (hCG),human placental lactogen (HPL), and other hormones.
