As with sarcomas in general , leiomyosarcomas have spindle cells . several mitoses are seen here , just in this one high power field 正如肉瘤的一般特点，平滑肌肉瘤中可见梭形细胞，仅一个高倍视野中就可见多个病理性核分裂象。

Figure 2 . b , on high - power magnification microscopy , the specimen showed a patternless tissue culture - like appearance with multiple mitoses and extraasated red blood cells 图2b ，高倍显微镜检查，标本显示无图案的“组织培养样”表现，伴有大量有丝分裂和红细胞外渗。

At higher magnification , the neoplastic glands of gastric adenocarcinoma demonstrate mitoses , increased nuclear / cytoplasmic ratios , and hyperchromatism . there is a desmoplastic stromal reaction to the infiltrating glands 高倍镜下，胃腺癌腺体细胞分裂象多见，核质比增加，着色过深。浸润腺体后结缔组织增生。

( 4 ) although the majority of bmn cells " mitoses are normal mitoses , there are still some abnormal phenomena found such as analogous amitoses , mitoses in multiploid cells and endomitoses K ） bmn细胞有丝分裂以正常有丝分裂为主，但同时存在多倍核有丝分裂、核内有丝分裂以及类似于缢缩和劈裂等的类无丝分裂等现象。

The reasults are summed up as following : 1 the study on chromosomes and mitoses of bmn cells the cell line , bmn , is a silkworm cell line widely used in silkworm molecular genetics , cell engineering , gene engineering and baculovirus expression system but whose genetics and cytobiology studies are nearly untouched . the chromosomes and mitoses of the bmn cells are researched by the air - drying method and culturing cells on cover glasses 同时，还通过原代培养实验对新的家蚕胚胎细胞系的建立进行了探索和尝试，并对家蚕胚胎原代培养过程中出现的细胞和组织类型进行了观察、探讨与研究。 1bmn细胞有丝分裂及染色体研究bmn细胞是家蚕分子遗传学，细胞工程、基因工程和杆状病毒表达系统中广泛应用的家蚕细胞，但其遗传学和细胞生物学背景知之甚少。

This dissertaion , on the basis of the other studies , on the one hand , researched and analysed the chromosomes and mitoses of the cell line - bmn , which is widely used in the silkworm baculovirus expression system as an engineering cell . on the other hand , the dissertation attempted to explore establishment of the new silkworm embryoni cell line by primary culture 同时，家蚕体外细胞培养研究的进行，不仅可以为家蚕细胞生物学的基础理论研究提供良好的研究系统，而且在家蚕资源的开发与利用方面也具有重大的意义。本研究在借鉴前人研究的基础上，一方面对现在广泛应用于家蚕杆状病毒表达系统的工程细胞? bmn细胞的染色体和有丝分裂进行了研究与分析。
