In adult hematopoiesis, red blood cells (erythrocytes) are ultimately formed from which cell type?
A
Intestinal crypt stem cell (Lgr5+ stem cell)
B
Hematopoietic stem cell (HSC) in the bone marrow
C
Neural stem cell from the subventricular zone
D
Mesenchymal stem cell (MSC) in the bone marrow stroma
Verified step by step guidance1
Understand the process of hematopoiesis, which is the formation of blood cells including red blood cells (erythrocytes).
Identify the primary location where adult hematopoiesis occurs, which is the bone marrow.
Recognize that hematopoiesis starts from a specific type of stem cell capable of differentiating into all blood cell lineages.
Recall that the hematopoietic stem cell (HSC) is the multipotent stem cell in the bone marrow responsible for giving rise to all blood cells, including erythrocytes.
Conclude that red blood cells are ultimately formed from hematopoietic stem cells (HSCs) in the bone marrow, not from intestinal crypt stem cells, neural stem cells, or mesenchymal stem cells.
