Human B1 cells have been found to have marker profile of CD20+CD27+CD43+CD70- and could either be CD5+ or CD5-, which has been debated since. [3] CD5-CD72 is thought to mediate B cell-B cell interaction. What differentiates B1 cells from other B cells is the variable existence of CD5, CD86, IgM and IgD. [1]
Cells4Life is a private stem cell bank based in the United Kingdom. It procures, processes and stores human umbilical cord blood and tissue samples that may be used for stem cell treatments. Cells4Life is the largest provider of umbilical cord blood banking services in the UK, with over 50% of the UK market. [2]

Stem cell donations save lives—and they are often a selfless act to help a stranger. But one case involving a Chicago man with leukemia shows it can help the donor too—in profound ways.
The MZ B cells within this region typically express low-affinity polyreactive B-cell receptors (BCR), high levels of IgM, Toll-like receptors (TLRs), CD21, CD1, CD9, CD27 with low to negligible levels of secreted-IgD, CD23, CD5, and CD11b that help to distinguish them phenotypically from follicular (FO) B cells and B1 B cells.

When reintroduced to antigen, some of these B1 cells can differentiate into memory B cells without interacting with a T cell. [4] These B cells produce IgM antibodies to help clear infection. [20] T-bet memory B cells. T-bet B cells are a subset that have been found to express the transcription factor T-bet. T-bet is associated with class ...
This remarkable potential makes them useful for basic research on the function of the human body, for drug discovery and testing, and as a source of cells and tissues for transplantation medicine. In 1998, Thomson's Lab was the first to report the successful isolation of human embryonic stem cells.
Regulatory B cells (Bregs or B reg cells) represent a small population of B cells that participates in immunomodulation and in the suppression of immune responses. The population of Bregs can be further separated into different human or murine subsets such as B10 cells, marginal zone B cells, Br1 cells, GrB + B cells, CD9 + B cells, and even some plasmablasts or plasma cells.
