What to Pack for the San Francisco Weather in July. While most people come packed for warm, sunny days, I recommend coming with a few long sleeved items so you have something to keep you warm as the evenings cool down. For the San Francisco weather in July, I typically wear short sleeved shirts and pants during the day. You could probably bring along some shorts too. Since it's breezy here in July, you will find it a bit too cool most of the time for shorts.
Bone marrow is the soft, flexible connective tissue within bone cavities. A component of the lymphatic system, bone marrow functions primarily to produce blood cells and to store fat. Red marrow contains hematopoietic stem cells that produce two other types of stem cells: myeloid stem cells and lymphoid stem cells. 2  These cells develop into red blood cells, white blood cells, or platelets.
Yellow marrow has a much higher amount of fat cells than red marrow. Both types of marrow contain blood vessels. Stem Cells The bone marrow works like a âfactoryâ that produces all of the cells that are found in the bone marrow and in the peripheral blood stream.This factory is dependent on the function of the pluripotent stem cells.oth types of marrow contain blood vessels.
