Protein profile of basal prostate epithelial progenitor cells--stage-specific embryonal antigen 4 expressing cells have enhanced regenerative potential in vivo.
The long-term propagation of basal prostate progenitor cells ex vivo has been very difficult in the past. The development of novel methods to expand prostate progenitor cells in vitro allows determining their cell surface phenotype in greater detail. Mouse (Lin(-)Sca-1(+) CD49f(+) Trop2(high)-phenotype) and human (Lin(-) CD49f(+) TROP2(high)) basal prostate progenitor cells were expanded in vitro. Human and mouse cells were screened using 242 anti-human or 176 antimouse monoclonal antibodies recognizing the cell surface protein profile. Quantitative expression was evaluated at the single-cell level using flow cytometry. Differentially expressed cell surface proteins were evaluated in conjunction with the known CD49f(+)/TROP2(high) phenotype of basal prostate progenitor cells and characterized by in vivo sandwich-transplantation experiments using nude mice. The phenotype of basal prostate progenitor cells was determined as CD9(+)/CD24(+)/CD29(+)/CD44(+)/CD47(+)/CD49f(+)/CD104(+)/CD147(+)/CD326(+)/Trop2(high) of mouse as well as human origin. Our analysis revealed several proteins, such as CD13, Syndecan-1 and stage-specific embryonal antigens (SSEAs), as being differentially expressed on murine and human CD49f(+) TROP2(+) basal prostate progenitor cells. Transplantation experiments suggest that CD49f(+) TROP2(high) SSEA-4(high) human prostate basal progenitor cells to be more potent to regenerate prostate tubules in vivo as compared with CD49f(+) TROP2(high) or CD49f(+) TROP2(high) SSEA-4(low) cells. Determination of the cell surface protein profile of functionally defined murine and human basal prostate progenitor cells reveals differentially expressed proteins that may change the potency and regenerative function of epithelial progenitor cells within the prostate. SSEA-4 is a candidate cell surface marker that putatively enables a more accurate identification of the basal PESC lineage.Thomas Höfner, Corinna Klein, Christian Eisen, Teresa Rigo-Watermeier, Axel Haferkamp, Martin R Sprick

Tumour necrosis factor alpha production by polymorphonuclear neutrophils treated with mouse anti-human CD19 monoclonal antibody.
Polymorphonuclear neutrophils (PMNs) play pivotal roles as phagocytic cells in immune defence against bacteria and parasites, exerting their effects by production of reactive oxygen species, several cytokines, chemokines and by phagocytotic reaction. In our investigation of properties of activated PMNs, we discovered that one of the two kinds of mouse anti-human CD19 monoclonal antibodies (mAbs) clone SJ25-C1, weakly binds to freshly prepared PMNs. Moreover, the treatment of freshly prepared PMNs with anti-CD19 mAb (clone SJ25-C1) at 37 degrees C for 6 h induces the production and the secretion of tumour necrosis factor alpha (TNF alpha) by PMNs in vitro which was detectable in culture supernatants by bioassay using mouse cell line L929 cells. The concentration of TNF alpha secreted into the culture supernatant of PMNs cultured in the presence of anti-CD19 mAb (clone SJ25-C1) was higher than those of PMNs treated at 37 degrees C for 6 h with various PMN activators, such as anti-CD24 mAb, granulocytes-macrophage colony stimulation factor (GM-CSF) or interferon gamma (IFN gamma). In contrast, another clone of anti-CD19 mAb, HD37, did not bind to freshly prepared PMNs and failed to produce TNF alpha. To confirm that anti-CD19 mAb (clone SJ25-C1)-treated PMNs definitely produce TNF alpha, we measured the levels of intracellular expression of TNF alpha in PMNs permeabilized by saponin. These cells were treated with fluorescence-conjugated mouse anti-human TNF alpha mAb for detection of intracellular TNF alpha expression. Consequently, large amounts of intracellular TNF alpha were detected in PMNs treated with anti-CD19 mAb (clone SJ25-C1) but not in those treated with anti-CD19 mAb (clone HD37).Motoko Nishimura
