Every cell in the human body (except for the red blood cells) has a full set of genetics and thus, potentially can form any specialized cell. Specialization takes place while the embryo is developing. It is done by activation of specialized genes. In any given cell nucleus, some genes are active (meaning they are synthesizing the messenger RNA which will direct the synthesis of the specific protein which that gene uses to do whatever it is that it does) and some genes are not active. Other genes called introns never synthesize anything, but instead, they regulate the expression of the genes called extrons which do synthesize RNA. Biologists have not worked out all the details, but it seems that the introns are able to respond to the cues in the embryo that tell them what kind of cell their cell is supposed to be, and then they activate the relevant extrons. Cues come in the form of the shape of the embryo, the relative position of a given cell within the embryo, and the types of cells which are near a given cell. A lot more research remains to be done on this subject.
What else can I help you with?
How many different specialized cells are in the human body?
There are over 200 different specialized cell types in the human body, each with a unique structure and function. These cells work together to form tissues and organs, allowing the body to carry out various biological functions.
How many cells does the human body contain?
The human body is composed of billions of cells. Each organ in the body is comprised of thousands of tissues, each of which are formed by thousands of cells.
Explain how skeletal bones are formed?
You have specialized cells in your body (ostioblasts) that make bone matrix.
How is human tissue and stem cell similar?
Tissue is an ensemble of cells that make up the organs in the body. Stem cells are cells that can be transformed into any of the specialized cells that can be found in the tissues of the human body.
How often are brain cells replaced in the human body?
Brain cells are not typically replaced in the human body. The majority of brain cells are formed before birth and are not regenerated throughout life.
How many cells does the body contains?
The human body is composed of billions of cells. Each organ in the body is comprised of thousands of tissues, each of which are formed by thousands of cells.
Where is flagella formed?
Flagella is formed outside of the cells in the human body. Their main function is to allow liquids to move past the surface of these cells.
What might happen if the human body did not have cells tissues organs and organs systems to maintain homeostasis?
what might happen if the human body did not have specialized cells tissue organs and organ systems to maintain homeostasis
What are stem cells in human?
They exist all over your body, they are like needs in the body by becoming specialized; or forming into other kinds of cells like bone, muscle, and blood cells. Also nerve cells.
What is the speciality of a cell?
A specialized cell is a special cell that only has small tasks. They are only found in specific organs, so one cell does not travel throughout the body. In the human body, all of our cells are specialized cells. Hope this helps!
What cells is the human body made of?
When a human fetus is in its mother's womb, all of the cells that start to develop in it are stem cells. stem cells can form into any other type cell found in the human body. as the fetus continues to develop, the stem cells will change into whatever cells the baby needs(i.e., they will change into all the cells found in the human body)
Does the human body have more bacterial or human cells?
it has more human cells actually the human body has more bacterial cells. Although it may seem more likely that the human body would have more human cells than bacterial cells. -Vasillisa
