B cells and T cells both originate from the haematopoietic (or hematopoietic) stem cells located in the bone marrow.
T cells mature in the thymus. B cells mature in the secondary lymphoid tissues (such as the spleen).

Stem cells has the capability to regenerate and develop into any kind of tissue or organ, when supported with the external nutrients. So they are called as totipotent. There are two kinds of stem cell a)adult stem cells b)embryonic stem cells. There are various researches going on in this area .
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.
Stem cells in a fetus mature in the yellow bone marrow.
B-cells and T-cells are both produced in the bone marrow. B-cells stay in the bone marrow but T-cells migrate to the thymus
Bone Marrow
They both originate in the red bone marrow. B lymphocytes mature there. T lymphocytes mature in the thymus gland.

A plasma B cell is a B cell that has been activated to proliferate and produce antibodies against a specific antigen. A memory B cell is a B cell that lives a long time after an infection to provide long lasting immunity against that specific antigen. They both originate from the same B cell in your secondary lymph system. Once activated the specific B cell will proliferate into plasma B cells and memory B cells.
Stem cells develop into plasma cells and B cells also turn into plasma cells. Plasma cells have been exposed to an antigen and then produces and secretes antibodies.
What kind(s) of cells can develop from multipotent stem cells?A. Only cells that are closely related to the original stem cell B. Only cells that are identical to the original stem cell C. Any cells of the human body or the placenta D. Any cells of the human body. but not cells of the placenta
