A stem cell differentiates by making protein. The stem cell slowly changes itself into a specific cell type when it makes protein.

Hematopoietic stem cells
A stem cell can become any other type of specialized cell.
An embryonic stem cell potentially can develop into ANY cell in the body theoretically without limit to replenish, and an adult stem cell is only able to mature into a specialised tissue cell from which tissue the cell is positioned.
A stem cell is undifferentiated.
stem cells can turn into any cell of the body and preform their function.
Stem cells divide through mitosis making two cells known as daughter cells. One daughter cell becomes a stem cell and the other cell differentiates into, or turns into, the tissue the stem cell is meant to maintain.
It serves the site of T cell differentiation
The stem cell "culture" is the medium in which the stem cell is able to divide and grow.

Please be patient with me. I've had to look this up. It appears that the blood cells differentiate from a common stem cell. They differentiate into two stem cells: 1. a myeloid stem cell. The myeloid stem cell matures into a CFU-GEMM progenitor cell which farther differentiates into five progenitors for eosinophils, basophils, neutrophils, monocyte, platelets, and red blood cells and 2. The lymphoid stem cell then differentiates into pro B and pro T cells and on to B lymphocytes and T lymphocytes. I believe it is the T lymphocyte which is known as the killer cell. There are many steps in this process and two of the cells also become tissue cells. However, getting back to your original question; there is some process as cells differentiate, (become different cells), from a common stem cells that turns some genes on and other genes off. All cells have the same DNA within the same organism, but some genes or turned off in some cells.

You are making the assumption that stem cell research is in the first place a bad idea. You have made your mind up about it and are only now searching for information to validate that gut feeling. But don't sweat it. Its actually human instinct to do this. A better question would be, "is stem cell research good or bad and why?"
Technically, a stem cell is a type of cell that can be transformed into any type of cell, so any type of stem cell can be transformed into a cell that makes fat and/or bone...
