Each germ cell had chromatoid body except for the spermatogonium of Al type, and the chromatoid body became small and dispersed with the cell developing constantly, disappearing completely in the sperm. 黄颡鱼除A1型精原细胞外的各期生殖细胞都存在拟染色体,并且随着细胞的不断发育拟染色体逐渐变小分散,最后在精子内完全消失。
The results showed that the spermatogonium was oval with few mitochondria. The chromatin was relatively dispersed. 结果表明,耳鲍精原细胞呈近椭圆形,染色质分布较均匀,线粒体较少;
The results show that, from spermatogonium stage to secondary spermatocyte stage, there exist neighboring gap junctions and septate junctions between spermatogenic cells, and desmosomes between spermatogonia. 结果表明,从精原细胞期到次级精母细胞期,在生精细胞之间存在间隙连接与分隔连接,并且两种连接相互邻接,桥粒仅在精原细胞之间发现;
Spermatogenic cells remained at the stage of spermatogonium and the endoplasmic reticulum of sustentacular cells expanded abnormally as cystic structure. 精曲小管中无精子生成,生精细胞停滞在精原细胞阶段,支持细胞的内质网异常地扩大呈囊泡状。
RESULTS: The immunostaining of p38 MAPK was seen in spermatogonium of 2 week old mice testes. 结果:在2周龄小鼠睾丸生精小管上皮中即可观察到p38MAPK免疫阳性反应,免疫反应阳性细胞为精原细胞;
The immunolocalization of p38 MAPK was in spermatogonium and primary spermatocyte with positive substance in nucleus. 6,7周龄小鼠睾丸中p38MAPK表达较丰富,免疫反应阳性细胞为精原细胞和初级精母细胞,免疫阳性反应物均主要位于细胞核内。
The testis at spermatogonium phase is small and transparent, and the spermatogenetic cells in seminiferous tubule primarily consist of spermatogonia; 精原细胞期,精巢小,透明乳白色,生精小管内的生殖细胞以精原细胞为主;
The RBE of tritium radiation measured in mouse spermatogonium 以小鼠精原细胞数的变化检测氚辐射的相对生物效应
The results show that, there are typical Golgi apparatus in spermatogonium, they are located near the nuclear membrane, and the saccules are connected by connective tubules. 结果表明:精原细胞内,高尔基体结构典型,分布在核膜附近,许多膜囊通过连接小管相互连接。
It was difficult to distinguish oogonium from spermatogonium according to the shape and size of gonium under light microscope. 在光镜下难以根据性原细胞的形态和大小区分卵原细胞和精原细胞。
The results showed that there were membrane interdigitation between sertoli cells in the spermatogenesis proliferation, which coincided with the proliferation of spermatogonium and the increasing size of spermatogenetic cysts. 结果表明,在精原细胞增生期,支持细胞间存在镶嵌连接,与精原细胞增生以及生精小囊的体积变大相适应;
Adaptive Response of Spermatogonium in Mice Exposed to Tritium at Low Doses 小剂量氚照射诱导的小鼠精原细胞适应性反应
Typical rough endoplasmic reticulum ( RER) were not seen during the process of spermatogenesis, only vesicular RER appeared and smooth endoplasmic reticulum ( SER) only presented at spermatogonium stage. 部分溶酶体构成精子顶体的一部分.精子发生的全过程中,未见典型的粗面内质网(RER),仅见泡状粗面内质网(VRER);
Results The cytoplasm of mesenchymal cell and spermatogonium in test group showed hydropic degeneration. 结果实验组小鼠睾丸组织中间质细胞和精原细胞胞质呈水样变性,出现红染细小的颗粒状物质,颗粒周围有大小不等的淡染区。
Adaptive response of spermatogonium in the mice exposed to 3H β rays at low dose was observed by using chromosome aberration analysis. 通过精原细胞染色体畸变分析,观察小剂量氚照射诱导的适应性反应。
The results showed: ( 1) There are the EGF-receptors on Cell membrane of spermatogonium, spermatocyte, spermatid, sperm, Sertoli cell, epididymis epithelium, prostate gland epithelium. 结果表明:(1)在人类睾丸内的精原细胞、精母细胞、精子细胞、精子及支持细胞、附睾上皮细胞、前列腺上皮细胞和射出精子的顶体区、尾部的膜上均有EGF-R存在。
In the mouse seminiferous tubules, all of spermatogonium and spermatocyte expressed OT positive products. 在小鼠的生精小管内,精原细胞和各级精母细胞均有催产素阳性产物表达。
