Purpose: To investigate the effects of a disintegrin and metalloproteinase 28(ADAM28) antisense oligodeoxynucleotide (AS-ODN) on proliferation, differentiation and apoptosis of human periodontal ligament stem cell(HPDLSC) and possible mechanism.
Methods: HPDLSC was isolated, cultured in vitro and identified. Synthetic ADAM28 AS-ODN and S-ODN were transfected into HPDLSC, respectively. MTT chromatometry, enzyme dynamics and flow cytometry (FCM) were used to detect the effects of ADAM28 AS-ODN on biological characteristics of HPDLSC. Statistical significance was assessed by the Student-Newman-Keuls (SNK) test with SPSS 13.0 software package.
Results: In ADAM28 AS-ODN group, the proliferation activity and index of HPDLSC were significantly lower than those of S-ODN group and untransfected group, alkaline phosphatase(ALP) secretion level and percentage of apoptotic cells went up obviously. Significant difference was detected between AS-ODN group and other groups (P<0.01).
Conclusions: ADAM28 AS-ODN could inhibit HPDLSC proliferation and influence the changes of cell cycle, promote ALP secretion and induce HPDLSC apoptosis significantly.

This study was to explore the effects of a disintegrin and metalloproteinase 28 (ADAM28) on the proliferation, differentiation, and apoptosis of human gingival fibroblasts (HGFs) and probable mechanism. After ADAM28 antisense oligodeoxynucleotide (AS-ODN) and sense oligodeoxynucleotide (S-ODN) were transfected into HGFs by Lipofectamine 2000, respectively, the expression discrepancies of ADAM28 among various groups were evaluated by reverse transcription-polymerase chain reaction (RT-PCR) and Western-blotting. Methabenzthiazuron (MTT) and cell-cycle assays were used to test the HGFs proliferation activity.

Purpose: To study the effects of a disintegrin and metalloproteinase 28 (ADAM28) antisense oligodeoxynucleotide (AS-ODN) on proliferation, differentiation and apoptosis of human gingival fibroblasts (HGFs), and analyze the possible mechanism.
Methods: Cell culture, gene transfection, MTT chromatometry, enzyme dynamics, and flow cytometry (FCM) techniques were used to detect the effects of ADAM28 AS-ODN on biological characteristics of HGFs after transfected into HGFs. The statistical differences were evaluated by SNK test with SPSS 16.

Introduction: The purpose of this study was to investigate the influence of a disintegrin and metalloproteinase 28 (ADAM28) on the proliferation, differentiation, and apoptosis of human dental pulp stem cells (HDPSCs) and possible mechanism.
Methods: After ADAM28 eukaryotic plasmid and antisense oligodeoxynucleotides (AS-ODNs) were constructed and respectively transfected into HDPSCs by Lipofectamine 2000, the ADAM28 expression levels among diverse groups were estimated by reverse transcription polymerase chain reaction (RT-PCR) and western blotting. Methabenzthiazuron (MTT) and cell cycle assays were used to test the HDPSCs proliferation activity.

Background: A disintegrin and metalloproteinase 28 (ADAM28) is considered to be the possible virulence gene for congenital hypoplasia of tooth root. Periodontal ligament stem cells (PDLSCs) are regarded as playing crucial roles in the developing process of the periodontium and are generally used in dental regenerative medicine. This study evaluates the influence of ADAM28 on the biologic property of human PDLSCs (HPDLSCs) and to postulate the possible mechanism of this influence.
