What is the starting point of B-cell development in the human body?
B-cell development begins in the bone marrow.
Describe the process that follows the asymmetric division of an HSC in B-cell development.
Describe the process that follows the asymmetric division of an HSC in B-cell development.
It leads through a series of progressively differentiated progenitor stages to produce common lymphoid progenitors (CLPs).
What types of cells can common lymphoid progenitors (CLPs) develop into?

Study Notes
Hematopoiesis Overview
- Hematopoiesis refers to the formation and development of blood cells in the body.
- The process begins during embryonic development and continues throughout the life cycle.
Ontogeny of the Hematopoietic System
- The hematopoietic system develops differently in mice and humans.
- Key stages include the transition from early stem cells to more specialized cells.
B-cell Development
- Initiated in the bone marrow from hematopoietic stem cells (HSCs) through asymmetric division.
- HSCs give rise to a series of progenitor stages, gradually differentiating into more specialized cells.
- Common lymphoid progenitors (CLPs) emerge from this process, capable of developing into B cells or T cells.
- B-cell development is critical for the adaptive immune response, playing a key role in antibody production and immune memory.
