What is the primary function of hematopoietic stem cells?

Hematopoietic stem cells have the unique ability to continuously renew themselves and generate progenitor cells, which are the precursors of all blood cells.

Which of the following is NOT a characteristic of hematopoietic stem cells?

Hematopoietic stem cells are pluripotent, meaning they can differentiate into various types of blood cells. However, they do not directly differentiate into fully mature blood cells. This process is done by the progenitor cells they produce.

What is the primary site of hematopoiesis in the adult human?

Bone marrow is the primary site of hematopoiesis in adults. It provides a rich environment for the growth and differentiation of hematopoietic stem cells and progenitor cells.

What is the role of cytokines in hematopoiesis?

Cytokines are signaling molecules that regulate the growth, differentiation, and survival of hematopoietic cells. They act like messengers, guiding the development of blood cell lineages.

Which of the following cell lineages is derived from the lymphoid progenitor cell?

T lymphocytes (T cells) and B lymphocytes (B cells) are key components of the adaptive immune system. They originate from lymphoid progenitor cells, which are derived from hematopoietic stem cells.
