文题释义:
细胞周期:
是指细胞从一次分裂完成开始到下一次分裂结束所经历的全过程,分为间期与分裂期两个阶段。间期又分为3期,即DNA合成前期(G1期)、DNA合成期(S期)与DNA合成后期(G2期)。在1个细胞周期内,一般分裂间期占细胞周期的90%-95%,分裂期占细胞周期的5%-10%。
细胞增殖:是生物体的重要生命特征,细胞以分裂的方式进行增殖。单细胞生物以细胞分裂的方式产生新的个体。多细胞生物以细胞分裂的方式产生新的细胞,用来补充体内衰老或死亡的细胞。通过细胞分裂,可以将复制的遗传物质,平均地分配到两个子细胞中去。可见,细胞增殖是生物体生长、发育、繁殖和遗传的基础。

 

摘要
背景:
研究表明肿瘤细胞释放的生长因子及细胞因子等生物信号可将间充质干细胞迁移至肿瘤组织,进而使间充质干细胞分化形成微环境中的各种基质细胞,参与调节肿瘤细胞的生长。
目的:探讨人食管癌组织间充质干细胞对食管癌EC109细胞增殖和细胞周期的影响。
方法:从食管癌组织中分离和纯化出食管癌间充质干细胞,以不同数量(1×104,2×104,3×104,4×104个)与食管癌EC109细胞系共培养,采用MTT法检测人食管癌组织间充质干细胞对EC109细胞增殖的影响;流式细胞仪检测人食管癌组织间充质干细胞对EC109细胞周期的影响。
结果与结论:①随着人食管癌组织间充质干细胞数量增加和作用时间(24,48,72 h)的延长,人食管癌组织间充质干细胞对食管癌细胞株EC-109有抑制作用,细胞存活率明显下降,差异有显著性意义(P < 0.05);②随着人食管癌组织间充质干细胞数量的增加,食管癌细胞株EC-109 G1期细胞比例显著增高,G2期细胞比例显著降低;③结果表明,人食管癌组织间充质干细胞能抑制EC109细胞的增殖且改变细胞周期的分布,并呈一定的剂量和时间依赖性。

Abstract:

BACKGROUND: Studies have shown that biological signals such as growth factors and cytokines released from tumor cells can make mesenchymal stem cells migrate into tumor tissues, and then these cells differentiate into various stromal cells constituting a microenvironment to participate in the regulation of tumor cells.
OBJECTIVE: To investigate the effects of human esophageal cancer mesenchymal stem cells (hEC-MSCs) on the proliferation and cell cycle of human esophageal carcinoma cell line EC109.
METHODS: After isolation and purification, hEC-MSCs at 1×104, 2×104, 3×104, 4×104 were co-cultured with  EC109 cells, respectively. MTT method and flow cytometry were used to measure cell proliferation and cell cycle of EC109 cells, respectively.
RESULTS AND CONCLUSION: With the increased number from 1×104 to 4×104 and increased exposure time from 24 to 72 hours, hEC-MSCs inhibited the proliferation of EC109 cells, and the survival rate of EC109cells was decreased significantly (P < 0.05). Cell cycle analysis revealed a marked increase in the EC-109 G1 phase and a decrease in the EC-109 G2 phase in a number-dependent manner. To conclude, hEC-MSCs inhibit the proliferation of EC109 cells and vary the cell cycle in number- and time-dependent manners.
