Q1. What is Hematopoiesis? Explain the hematopoietic system of bone marrow.
- Hematopoiesis is the formation of all blood cells from stem cells.
- Hematopoietic Stem Cells (HSCs) are multipotent cells in the bone marrow.
- Bone marrow is the primary site of adult hematopoiesis.
- Stromal cells in bone marrow provide essential growth factors and cytokines.
Answer: Hematopoiesis is the continuous physiological process by which all blood cellular components are formed. This intricate process originates from a small population of self-renewing hematopoietic stem cells (HSCs) residing primarily in the bone marrow in adults. These multipotent HSCs differentiate and mature into all types of blood cells, including red blood cells (erythrocytes), white blood cells (leukocytes like granulocytes, monocytes, lymphocytes), and platelets (thrombocytes).
