Immature B Cell Marker

B lymphocytes (B cells) are crucial components of the adaptive immune system, primarily responsible for producing antibodies and functioning as antigen-presenting cells. Their development is a tightly regulated, stepwise process that begins in the bone marrow and culminates in the periphery. During this complex maturation, B cells express a distinct set of cell surface markers at each stage, enabling researchers to identify, isolate, and study specific developmental populations. Immature B cells represent a pivotal transition stage, characterized by the acquisition of a functional B cell receptor (BCR) and undergoing crucial selection processes before fully maturing.
