| 稳定的体外细胞培养体系，可以为基因功能和宿主病原相互作用研究提供平台。本研究通过对四脊滑螯虾(Cherax quadricarinatus)造血组织(hematopoietic tissue， HPT)细胞的体外培养条件进行优化，以期获得状态稳定、活力良好的造血组织细胞培养物。我们从四脊滑螯虾中分离提取造血组织细胞后，通过对培养基种类(L-15、Express Five、DMEM)，谷氨酰胺浓度(0、1%、5%、10%)，胎牛血清浓度(0、1%、5%、10%)，以及体外培养温度(20、27 ℃)等培养条件进行优化。细胞形态观察和细胞活力分析结果表明，HPT细胞在添加1%青霉素链霉素、10%L-谷氨酰胺、1%胎牛血清的L-15培养基中状态最佳，在20 ℃培养温度下能存活30 d左右。这些培养条件将有利于四脊滑螯虾造血组织细胞的体外培养。 |

| Abstract: |
| A stable cell culture system in vitro can provide a platform for the study of gene function and host-pathogen interaction. In this study, the culture conditions of hematopoietic tissue (HPT) cells of crayfish (Cherax quadricarinatus) were optimized to generate stable HPT culture with high viability. After isolating and extracting HPT cells from crayfish, we compared the culture conditions, such as culture medium (L-15, Express Five and DMEM), glutamine concentration (0, 1%, 5% and 10%), fetal bovine serum concentration (0, 1%, 5% and 10%), and culture temperature (20 ℃ and 27 ℃). Results of cell morphology observation and cell viability analysis showed that the cell culture of L-15 medium was optimized by supplemented with 1% penicillin-streptomycin, 10% L-glutamine and 1% fetal bovine serum, in which the cells could survive for about 30 days at 20 ℃. The culture conditions are helpful for in vitro culture of hematopoietic tissue cells of crayfish. |
