Question

In the cell theory, Rudolf Vichow told that all cells arise from pre-existing cells. But the Red Blood Cells and some other types of cell arise from bone marrow, is the cell theory not true for them?

Answer 1

Dear Student, Red blood cells are produced in the red bone marrow by stem cells also known as hemocytoblast, if stem cells becomes proerythroblast, it will commit to form red blood cells by differentiation. So, red blood cells are formed from pre-existing cells. Therefore, Rudolf Virchow cell theory is also applicable for red blood cells. Thank You!
