From where does a stem cell receives a signal for differentiating in to a new type of cell?

Stem cells are basically blank cells that, in most cases, have the ability to become a variety of other cells. They are found in bone marrow, blood, the brain, skeletal muscle, fat and even the skin. While the main controversy exists over embryonic stem cells as they have the ability to become just about any cell, we are still able to utilize adult stem cells in a handful of useful ways. The idea is that scientists can, with the right research, learn to program stem cells to become new spinal cord tissue or new brain tissue, repairing damage that right now is irreversible.
Stem cells "know" what type of cell to become due to internal genetic code, external chemical messages, or coming in physical contact with differentiated cells.

What are the similarities and differences between research on and the use of adult stem cells and embryonic stem cells?
One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become. Embryonic stem cell can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin.
What is the difference between totipotent stem cells and multipotent stem cells?
totipotency is the ability of stem cells to differentiate into all the 216 different cell types in the body. In the blastocyst stage the outer layer of cells form the placenta, but the inner layer of cells forms the embryo but it doesnt have the ability to differentiate into cell types such as the placenta. These cells are called pluripotent stem cells.
Why can stem cells be used to grow different types of tissue?
Stem cells are a special type of cell found in all multicellular organisms. They are undifferentiated and are capable of differentiating into a wide range of specialized cell types.

What happens when stem cell guy gets a signal?
when a stem cell guy gets a signal, it begins to differentiate or change into his destined cell type
What advantages do embryonic stem cell have over adult stem cells in medical research?
Human embryonic and adult stem cells each have advantages and disadvantages regarding potential use for cell-based regenerative therapies. ... Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin. Embryonic stem cells can be grown relatively easily in culture.

What is mixed with stem cell to make them grow and differentiate?
There is no one ingredient responsible for differentiating stem cells. The combination of solutes in the ECM (extra cellular matrix) that the stem cells reside in is responsible for their differentiation. For example, I wanted to see if I could get some stem cells to differentiate so I took my culture of cells and added olive oil to it. Olive oil contains many chemicals naturally however one in particular (DAG) proved to be capable of differentiating my stem cells into macrophages (a WBC defense cell). Long story short, no one really knows exactly what compounds in exactly what amounts are required to differentiate stem cells into what they want....and anyone with this knowledge is hoarding it until they get it published I'm sure. Hope that helps, Doc
