| 1 | Isolation and characterisation of human gingival margin-derived STRO-1/MACS^+ and MACS^-cell populations显示文摘Recently,gingival margin-derived stem/progenitor cells isolated via STRO-1/magnetic activated cell sorting(MACS) showed remarkable periodontal regenerative potential in vivo.As a second-stage investigation,the present study's aim was to perform in vitro characterisation and comparison of the stem/progenitor cell characteristics of sorted STRO-1-positive(MACS^+) and STRO-1-negative(MACS^-) cell populations from the human free gingival margin.Cells were isolated from the free gingiva using a minimally invasive technique and were magnetically sorted using anti-STRO-1 antibodies.Subsequently,the MACS^+ and MACS^- cell fractions were characterized by flow cytometry for expression of CD14,CD34,CD45,CD73,CD90,CD105,CD146/MUC18 and STRO-1.Colony-forming unit(CFU) and multilineage differentiation potential were assayed for both cell fractions.Mineralisation marker expression was examined using real-time polymerase chain reaction(PCR).MACS^+ and MACS- cell fractions showed plastic adherence.MACS^+ cells,in contrast to MACS- cells,showed all of the predefined mesenchymal stem/progenitor cell characteristics and a significantly higher number of CFUs(P<0.01).More than 95%of MACS^+ cells expressed CD105,CD90 and CD73;lacked the haematopoietic markers CD45,CD34 and CD14,and expressed STRO-1 and CD146/MUC18.MACS- cells showed a different surface marker expression profile,with almost no expression of CD14 or STRO-1,and more than 95%of these cells expressed CD73,CD90 and CD146/MUC18,as well as the haematopoietic markers CD34 and CD45 and CD105.MACS^+ cells could be differentiated along osteoblastic,adipocytic and chondroblastic lineages.In contrast,MACS- cells demonstrated slight osteogenic potential.Unstimulated MACS^+ cells showed significantly higher expression of collagen I(P<0.05) and collagen III(P<0.01),whereas MACS^- cells demonstrated higher expression of osteonectin(P<0.05;MannWhitney).The present study is the first to compare gingival MACS^+ and MACS- cell populations demonstrating that MACS^+ cells,in contrast to MACS- cells,harbour stem/progenitor cell characteristics.This study also validates the effectiveness of the STRO-l/MACS^+technique for the isolation of gingival stem/progenitor cells.Human free gingival margin-derived STRO-1/MACS^+ cells are a unique renewable source of multipotent stem/progenitor cells. | Karim M Fawzy El-Sayed Sebastian Paris Christian Graetz Neemat Kassem Mohamed Mekhemar Hendrick Ungefroren Fred Fndrich Christof Drfer | 2015 | International Journal of Oral Science2015,7,2: | 6 |

| 14 | Praziquantel efficacy against Schistosoma mansoni among HIV-1 infected and uninfected adults living in fishing villages along Lake Victoria, Northwest Tanzania显示文摘Background:Animal studies have demonstrated that functional immune responses,as determined by the levels of CD4+cell counts and anti-schistosome antibodies responses,determine the efficacy of praziquantel.Based on this evidence,it has been hypothesised that the immunodeficiency effects of the human immunodeficiency virus(HIV)-1 infection may affect the efficacy of praziquantel in co-infected human hosts.Thus,the present study assessed the efficacy of praziquantel by comparing parasitological cure rates and the reduction in infection intensity in HIV-1 seronegative individuals infected with S.mansoni and HIV-1 seropositive individuals co-infected with S.mansoni,following treatment with a single oral dose of praziquantel.Methods:This was a prospective longitudinal study which included,at baseline,555 S.mansoni infected adults aged 21-55 years,who were either co-infected or not with HIV-1 and who lived in fishing villages along Lake Victoria in Northwest Tanzania.These individuals were treated with a single oral dose of praziquantel(40 mg/kg)and,at 12 weeks,single stool samples were obtained and examined for S.mansoni eggs using the Kato-Katz technique.Finger prick and venous blood samples were collected for HIV-1 screening and CD4+cell quantification.Results:The parasitological cure rate did not differ significantly from the HIV-1 serostatus(P=0.12):among the co-infected individuals,the cure rate was 48.3%(14/29),and among the individuals infected only with S.mansoni,the cure rate was 62.6%(329/526).The egg reduction rate did not vary with the HIV-1 serostatus(P=0.22):77.22%for HIV-1 seronegative and 75%for HIV-1 seropositive individuals.The level of CD4^(+) cell counts(median 228 cells/μL:range 202-380 cells)did not influence the cure rate(P=0.23)or the reduction in the intensity of the infection(P=0.37).Conclusion:The HIV-1 infection per se or its moderate immunodeficiency effects,demonstrated by the range of CD4^(+) cell counts observed in co-infected individuals,did not affect praziquantel efficacy,as measured by the parasitological cure rate and the reduction in intensity of infection in the present study cohort. | Humphrey D Mazigo David W Dunne Safari M Kinung’hi Fred Nuwaha | 2014 | Infectious Diseases of Poverty2014,3,1: | 1 |
