文题释义:
前列腺癌DU145细胞:DU145是从一位有3年淋巴细胞白血病史的前列腺癌患者的脑部转移灶中建立的。该细胞系未检测到激素敏感性,酸性磷酸酶阳性,单个的细胞可在软琼脂中形成集落。对此细胞和原始肿瘤的亚显微结构分析可见微绒毛、微丝、细胞桥粒、线粒体、发达的高尔基体和异质溶酶体。
克隆形成率:反映细胞群体依赖性和增殖能力2个重要性状。由于细胞生物学性状不同,细胞克隆形成率差别也很大,一般初代培养细胞克隆形成率弱,传代细胞系强;二倍体细胞克隆形成率弱,转化细胞系强;正常细胞克隆形成率弱,肿瘤细胞强。
 
背景:研究表明,骨髓间充质干细胞与肿瘤的发生和发展具有密切关系,不仅表现为对肿瘤有明显的募集作用,还表现在干预肿瘤细胞的生物学行为。
目的:探讨骨髓间充质干细胞对前列腺癌Du145细胞生物学行为的影响。
方法:采集健康成人骨髓间充质干细胞,实验组将前列腺癌Du145细胞和骨髓间充质干细胞分别接种于Transwell小室的上下两室进行共培养,阳性对照组为人真皮成纤维细胞HDF-a细胞与人前列腺癌Du145细胞共培养,阴性对照组为野生型前列腺癌Du145细胞单独培养。培养3 d后,流式细胞仪检测前列腺癌Du145细胞的细胞周期,软琼脂克隆形成实验检测细胞增殖活性,结晶紫染色观察Du145细胞迁移能力。
结果与结论:①与阳性对照组相比,实验组处于G2/M+S期的细胞比例、透过滤膜数量和克隆形成数明显减少;②结果表明,骨髓间充质干细胞通过缩短前列腺癌Du145细胞G2/M+S期,抑制前列腺癌Du145细胞的增殖和侵袭能力,为前列腺癌的治疗提供新的思路和方法。

Abstract:

BACKGROUND: Bone marrow mesenchymal stem cells have a close relationship with tumor occurrence and development, which are not only involved in tumor recruitment but impact the biological behavior of tumor cells.

OBJECTIVE: To investigate the effect of bone marrow mesenchymal stem cells on the biological behavior prostate cancer cell line.
METHODS: Human bone marrow mesenchymal stem cells from healthy adults were collected and cultured in vitro. Cell morphology and cell markers were observed. Using the Transwell technique, human dermal fibroblasts HDF-a were co-cultured with human prostate carcinoma DU145 cells in positive control group, wild-type prostate carcinoma DU145 cells cultured alone in negative control group, and bone marrow mesenchymal stem cells co-cultured with human prostate carcinoma DU145 cells in experimental group. Flow cytometry assay was used to detect the cell cycle of prostate carcinoma DU145 cells, soft agar colony formation assay performed to detect cell proliferative ability, and crystal violet staining used to observe DU145 cell migration at 3 days after culture.
RESULTS AND CONCLUSION: Compared with the negative control group, cell proportion at G2/M+S phase, number of transmembrane cells and colony counting were significantly decreased in the experimental group. These findings indicate that bone marrow mesenchymal stem cells may inhibit the proliferation and invasion of prostate carcinoma DU145 cells by shortening the G2/M+S phase, thereby providing a new insight into the treatment of human prostate cancer.
