What else can I help you with?
A blastocyst is a group of cells that forms after a human egg is fertilized. The blastocyst consists of two types of cells. Some of these cells will become the placenta. What do the other cells become?
The other cells in the blastocyst will differentiate into the embryo itself. They will later develop into the various tissues and organs that make up the human body.
What happens during the morula stage of human development?
During the morula stage of human development, the zygote undergoes several rounds of cell division to form a solid ball of cells. At this stage, the cells are still undifferentiated and are tightly packed together. The morula will eventually develop into a blastocyst, which is necessary for successful implantation into the uterus.
What is human embryo called at the time of implantation?
At the time of implantation, a human embryo is called a blastocyst. This stage occurs about 5-7 days after fertilization and marks the implantation of the embryo into the uterus lining.
What is the process that takes place last in the development of a human being?
Blastocyst formation
What is the part of the blastocyst that promotes implantation and produces hCG?
The trophoblast is the part of the blastocyst that promotes implantation and produces human chorionic gonadotropin (hCG). This hormone helps maintain the uterine lining during early pregnancy and is the basis for most pregnancy tests.

How do scientists extract human embryonic stem cells?
Human embryonic stem cells are typically extracted from the inner cell mass of a blastocyst, a structure that forms a few days after fertilization. The blastocyst is usually donated for research purposes with informed consent from the donors. Researchers can then extract the stem cells from the inner cell mass by using techniques that dissociate the cells from the embryo.
What is the mass of stem cells produced in the first few days after ferlization called?
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.

What kind of the stem cells can develop into any kind of cells in the human body?
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.

How many weeks into pregnancy does the zygote appear?
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.
What happens to aging muscle cells?
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.
What hormone is produced by the blastocyst?
In humans, the outer layer of the blastocyst, called the trophoblast, secretes human chorionic gonadotrophin (hCG),human placental lactogen (HPL), and other hormones.

How do cells become a full human body?
the chromosome and the
How does the cell become millions of cells that make up the humans body?
The cells become millions of cells in the human body through the process of replication.
