| 摘 要： | 为改善马氏珠母贝 (Pinctada martensii) 外套膜组织和细胞体外培养的效果，探究了添加不同浓度的天然提取物茶多酚对外套膜组织和细胞培养液的优化效果。结果显示，当茶多酚的添加量为0.5%~2.0% (体积分数) 时，马氏珠母贝外套膜细胞的生物活性显著高于对照组 (P<0.05)；当添加量为1.0%时，相对细胞生物活性最高。5组完全培养液 (0%、0.5%、1.0%、1.5%、2.0%组) 均能较好地促进细胞的生长增殖，且细胞的生长曲线均呈“S”型；当培养液中茶多酚的添加量为1.0%时，外套膜细胞增殖效果最优。研究表明，马氏珠母贝外套膜组织和细胞在最适培养液中均能大量增殖游离细胞，且正常分泌珍珠质，其中培养液中的钙离子 (Ca2+) 浓度随着组织和细胞增殖过程呈先减后增的趋势，但始终低于初始浓度。研究结果进一步优化了马氏珠母贝外套膜组织和细胞培养液，为推动马氏珠母贝无核珍珠的培育提供了理论基础。

| Abstract: | To improve the effects of tea polyphenols on tissue and cell culture of Pinctada martensii mantle, we explored the optimization effect of adding different concentrations of natural extract tea polyphenols on the mantle tissue and cell culture medium. The results show that when the added amount of tea polyphenols was 0.5%–2.0%, the biological activity of P. martensii mantle cells was significantly higher than that of the control group, and the best added amount was 1.0%. The five groups of completely culture medium (0%, 0.5%, 1.0%, 1.5% and 2.0%) all promoted the growth and proliferation of cells, and the growth curves of the cells were all in an |
