目的对大肠腺瘤细胞原代培养的方法作进一步的改进。

However, the primary cell culture methods which are employed now have many defects.

然而，目前正被应用的滋养层细胞分离、培养、纯化方法均存在一定程度的缺陷。

Running from a primary cell, it operates down to 1.8V, whereas most battery PMICs operate from 3V.

从一次电池运行时，它工作在低至1.8V，而大多数电池的PMIC从3V操作。

Primary cell culture was made from 23 malignant trophoblastic tumors and 19 normal early pregnant villi.

本文对23例恶性滋养细胞和19例正常早孕绒毛滋养细胞进行了原代培养。

We further developed the primary cell culture if the tumor cells which would lead to better use of this genetic model.

同时还建立了原代培养的肿瘤细胞，提升了模型的利用效率。
