- Description
- Description: The 2H7 monoclonal antibody reacts with human CD20, a 33-36 kDa transmembrane protein. CD20 is expressed by developing B cells as well as mature B cells but not plasma cells. CD20 has been detected at low levels on a small subset of mature T cells. It is suggested that CD20 plays a role in B-cell activation.

Immunomagnetic selection and subsequent FACS were used to isolate the five populations from pediatric and adult human BM. Shown are the FACS dot plots with sorting gates to obtain CD34 + CD19 - ProB cells, CD34 + CD19 + PreBI cells, CD34 - CD19 + CD20 dim PreBII large cells, CD34 - CD19 + CD20 - PreBII small cells, and CD34 - CD19 + CD20 high IgM + Immature B cells.

- Fig. 4 IGF-1-dependent induction of cancer stem cell markers CD20, CD133, and CD271 (NGFR) on melanoma cells. a Melanoma cells (WM3749) co-cultured with TAB cells (days 3 and 9) show high expression of CD20 ( middle and right panels ) compared with the control culture ( left panel ) as determined by FACS analysis. Melanoma cells were co-stained with anti-CD146 (MCAM, PE-conjugated) and anti-CD20 (FITC-conjugated) antibodies to distinguish them from B cells, which are CD146-negative;percentages indicate co-expression of both markers on the malignant cells. b Melanoma cells (WM3749) co-cultured with TAB cells (day 6) show high expression of CD20, CD133 and CD271 ( left panel ) compared with minimal or low expression of those markers when tumor cells are co-cultured with NB cells ( right panel ). Co-culture of melanoma cells with TAB cells did not modulate the expression of CD144 (vascular-endothelial cadherin marker) that are normally expressed by aggressive melanomas (data not shown). Induction of CD20, CD133, and CD271 was blocked when anti-IGF-1 neutralizing antibody (10 mug/ml) was used in the co-culture ( middle panel ). Anti-IL-1, anti-PDGF or anti-VEGF antibodies had no effect on CD marker expression (data not shown). Percentages indicate co-expression of CD20, CD133, or CD271on CD146 + melanoma cells. Results are representative of two independent experiments. c Melanoma cells(WM3749, WM989 and 451Lu) cultured in the presence of recombinant IGF-1 (25 ng/ml) for 5 days sh

Graph shows calculated theoretical absolute cell numbers (+-s.e.m., n = 3). Viable cells were assessed by trypan blue exclusion. Source data are provided as a Source Data file. b Primary human GC B cells were transduced with different oncogenes and oncogene combinations and monitored by flow cytometry. Graph shows the change in cell viability assessed by scatter characteristic by flow cytometry ( +- s.e.m., n = 3). Source data are provided as a Source Data file. c Primary human GC B cells were transduced with BCL2 in combination with other transcription factors in a pooled, competitive culture. Graph shows relative abundance of transcription factors or their mutant versions over four different timepoints ( n = 3). d Primary human GC B cells were transduced with the oncogenic cocktail BCL2 and BCL6 and cultured to day 73. Representative flow cytometry analysis ( n = 3) for the expression of the GC B cell markers CD38, CD20, CD19, CD80, CD22, CD95, CXCR4, and CD86.
