| 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 |

| 3 | Genome resequencing and transcriptome profiling reveal structural diversity and expression patterns of constitutive disease resistance genes in Huanglongbing-tolerant Poncirus trifoliata and its hybrids显示文摘Huanglongbing(HLB)is the most destructive bacterial disease of citrus worldwide.While most citrus varieties are susceptible to HLB,Poncirus trifoliata,a close relative of Citrus,and some of its hybrids with Citrus are tolerant to HLB.No specific HLB tolerance genes have been identified in P.trifoliata but recent studies have shown that constitutive disease resistance(CDR)genes were expressed at much higher levels in HLB-tolerant Poncirus hybrids and the expression of CDR genes was modulated by Candidatus Liberibacter asiaticus(CLas),the pathogen of HLB.The current study was undertaken to mine and characterize the CDR gene family in Citrus and Poncirus and to understand its association with HLB tolerance in Poncirus.We identified 17 CDR genes in two citrus genomes,deduced their structures,and investigated their phylogenetic relationships.We revealed that the expansion of the CDR family in Citrus seems to be due to segmental and tandem duplication events.Through genome resequencing and transcriptome sequencing,we identified eight CDR genes in the Poncirus genome(PtCDR1-PtCDR8).The number of SNPs was the highest in PtCDR2 and the lowest in PtCDR7.Most of the deletion and insertion events were observed in the UTR regions of Citrus and Poncirus CDR genes.PtCDR2 and PtCDR8 were in abundance in the leaf transcriptomes of two HLB-tolerant Poncirus genotypes and were also upregulated in HLB-tolerant,Poncirus hybrids as revealed by real-time PCR analysis.These two CDR genes seem to be good candidate genes for future studies of their role in citrus-CLas interactions. | Nidhi Rawat Brajendra Kumar Ute Albrecht Dongliang Du Ming Huang Qibin Yu Yi Zhang Yong-Ping Duan Kim D Bowman Fred G Gmitter Jr Zhanao Deng | 2017 | Horticulture Research2017,4,1: | 5 |
