Final answer:
The two types of stem cells in bone marrow are hematopoietic stem cells and mesenchymal stem cells, which are involved in blood cell and muscle cell production, respectively.
Step-by-step explanation:
The two types of stem cells found in the bone of the bone marrow are hematopoietic stem cells and mesenchymal stem cells. Hematopoietic stem cells are responsible for the production of red blood cells, white blood cells, and platelets, and they play a crucial role in the body's ability to replenish the blood cellular components. Mesenchymal stem cells give rise to various types of cells including those that form muscle tissues and other connective tissues.
