Leukopoiesis

What is the first step in the sequence of hematopoietic cell generation and maturation?

• Differentiation of stem cells

• Proliferation of progenitor cells

• Commitment to a specific lineage

• Self-renewal of hematopoietic stem cells

Pluripotent stem cells differentiate into which types of stem cells?

• Totipotent stem cells

• Multipotent stem cells

• Unipotent stem cells

• All of the above

What are the possible cell lines that the myeloid stem cell can differentiate into under the influence of specific cytokines?

• Erythrocytes, Megakaryocytes, Granulocytes, Monocytes

• Lymphocytes, Neurons, Osteoblasts, Chondrocytes

• Hepatocytes, Adipocytes, Myocytes, Fibroblasts

• Keratinocytes, Melanocytes, Endothelial cells, Smooth muscle cells

What is the role of neutrophils in granulocyte maturation?

• They are the first responders to infection.

• They help in the maturation of other granulocytes.

• They are involved in the production of antibodies.

• They play a role in blood clotting.

What is the function of eosinophils in the immune system?

• They produce antibodies to fight infections.

• They are involved in the destruction of parasites and allergic reactions.

• They transport oxygen in the blood.

• They help in blood clotting.

Basophils contribute to the body's defense mechanisms by:

• Releasing histamine and heparin during allergic reactions

• Producing antibodies to fight infections

• Engulfing and digesting pathogens

• Destroying infected host cells

What is the process of white blood cell formation called?

• Hematopoiesis

• Leukopoiesis

• Erythropoiesis

• Thrombopoiesis

In the leukopoiesis diagram, which cell type eventually becomes a macrophage?

• Neutrophil

• Eosinophil

• Basophil

• Monocyte

Identify the cell type that is a precursor to T lymphocytes in the leukopoiesis process.

• Thymocyte

• Erythrocyte

• Monocyte

• Basophil

What is the first stage of the granulocytic series that is identifiable by light microscopy?
