IPLB LD-652Y-5d cells infected with Lymantria xylina multiple nucleopolyhedrovirus were found that the infection cells were fused together and formed syncytial giant cells. This phenomenon is probably caused by the viral envelope fusion protein in the cell membrane of the infected cells.

Compared with the corresponding BEAS-2B cells, the shape of cell clone, the way of cell growth, the shape and quantity of cell and nuclear were not significantly changed in the 1st, 2nd, 5th passage BEAS-2BNNK cells. The shapes of cells and its nuclears of the 10th, 15th, 20th, 25th passage BEAS-2BNNK cells became round gradually, and the way of cell growth became from radio-form into membraniform and more than one nucleolus appeared.

BEAS-2BNNK细胞在第1、2、5代时细胞克隆形态及生长方式、细胞形态、细胞核形态及数目与相应代BEAS-2B无明显差异；第10、15、20、25代时细胞及胞核逐渐变圆，出现多个核仁，细胞由放射状生长逐渐变为膜状生长。

To mensurate the expression of MDR1 of different breast cancer cells from human breast cancer primary cells and MCF-7 breast cancer cell line,and the kill effect of chemotherapy drug with different breast cancer cells in vitro,and the change of the proporation and the expression of MDR1 of breast cancer stem cells after chemotherapy.

测定人乳腺癌标本和MCF-7中不同细胞亚群的MDR1表达情况；并测定化疗药物在体外对人乳腺癌原代细胞和MCF-7中不同细胞亚群的杀伤作用，以及在化疗药物干预后，乳腺癌干细胞的含量和MDR1表达的变化情况。

It shows that the embryogenic tissues are composed of a group of small meristematic cells at one end (embryo-proper cells), which are at different phages of cell division and many long cells at the other end (embryo-suspensor cells).

研究表明，胚性愈伤组织是由不同发育阶段的早期胚组成的细胞团，早期胚主要由长的胚柄细胞及其顶端的胚头细胞组成，而后者又具不同的分裂相。

Nestin-positive cells were mainly in the gastric mesenchyma and the neck region of the glands. In mucosa of small intestine, Musashi-1-positive cells and TERT-positive cells were mainly located between cell positions 4 and 7. Oct-4-positive cells were diffusely distributed in the crypts.

小肠黏膜中Musashi-1和TERT阳性细胞主要在距隐窝底部4~7个细胞的位置，Oct-4阳性细胞散在分布于腺体内，Nestin阳性细胞均分布在小肠黏膜间质，无腺体内着色。

Mesenchymal stem cells are multipotent cells derived from many adult tissues, which can differentiate into cells of the mesodermal lineage, such as adipocyte, osteocyte and chondrocyte, as well as cells of other embryonic lineages. They are a promising tool for tissue engineering.
