Hematopoietic cells are a type of stem cell that give rise to all types of blood cells in the body. This includes red blood cells, white blood cells, and platelets. These cells are essential for the proper functioning of the immune system and for transporting oxygen throughout the body. Research in hematopoietic cells focuses on understanding how these cells develop, differentiate, and function in both normal and diseased states. This research has important implications for treating conditions such as anemia, leukemia, and other blood disorders.
