The B cell-specific cell surface molecule CD19 is expressed at all stages of B cell development, including normal plasma cells, and mediates signal transduction via interaction with cytoplasmic effector proteins. Cross-linking CD19 on early human B l

A common sequela to allogeneic or autologous bone marrow transplantation (BMT) is a delay in the reconstitution of a functional B-cell immune response. Therefore, we examined whether the posttransplant BM microenvironment is deficient in supporting t

The interaction of normal human B cell precursors with the bone marrow (BM) stromal cells that support their growth and maturation is mediated by adhesion of B cell CD49d/CD29 (alpha 4 beta 1 integrin or VLA-4) to stromal cell signal transduction, we

The growth of human B cell precursors can be supported by bone marrow (BM) stromal cells and IL-7, but the identity of the responding population is unknown. In the current study, we examined the growth characteristics of FACS-purified CD10+/CD34+/cyt

The function of the cell surface molecule CD40 on B cell precursors (BCP) is not well understood. We now report studies using the L cell/CD40 system (anti-CD40 mAb immobilized on CD32+ mouse L cells) to assess the potential function of CD40 during hu

Self-renewal and differentiation of B-cell precursors is dependent on interactions with bone marrow (BM) stromal cells and associated extracellular matrix. We have recently developed an interleukin (IL)-7- dependent, BM-derived stromal cell culture t

Interleukin-4 (IL-4) regulates multiple stages of the antigen-dependent phase of B-cell development. However, its precise role in regulating B lymphopoiesis in bone marrow is not as well defined. We examined whether surface IgM- normal and leukemic h

Fetal bone marrow B lineage cells representing multiple stages of B cell development were isolated by two-color cell sorting and analyzed for immunoglobulin H and T-cell receptor (TCR) gamma and delta gene rearrangements. Analysis of CD10+/surface mu

Mammalian B-cell development can be viewed as a developmental performance with several acts. The acts are represented by checkpoints centered around commitment to the B-lineage and functional Ig gene rearrangement--culminating in expression of the pr

Development of mammalian B-lineage cells is characterized by progression through a series of checkpoints defined primarily by rearrangement and expression of immunoglobulin genes. Progression through these checkpoints is also influenced by stromal ce
