小鼠睾丸发育全过程中生精细胞的自发性凋亡
睾丸发育 小鼠生精细胞 自发性凋亡
font style='font-size:12px;'>
2012/11/6
以17组出生后不同发育阶段的昆明种正常小鼠睾丸组织为材料,采用TDT原位末端标记法在其石蜡组织切片上进行凋亡细胞原位检测,探讨小鼠睾丸发育全过程中生精细胞的自发性凋亡规律.结果发现:小鼠生精细胞从生后开始就存在自发性凋亡现象,生后1~15 d,凋亡精原细胞数目不断增加;至生后第15天时达到峰值,且15 d起个别初级精母细胞也开始出现凋亡;至27 d时,极少数次级精母细胞和精子细胞出现凋亡;至30 ...

为了研究大林姬鼠两亚种(韩国的指名亚种及中国东北和内蒙古地区的东北亚种)线粒体DNA 的变异程度并确定朝鲜亚种的分类地位,我们分别将来自韩国和中国东北长白山地区的两亚种的线粒体DNA 的细胞色素b 基因和控制区进行了测序分析。我们将测序所得到细胞色素b 基因序列与来自基因库的大林姬鼠5 个亚种的相应的单倍型进行了分析,结果显示大林姬鼠可分为4 个类群[类群1:韩国大林姬鼠指名亚种;类群2:中国长白...
昆虫抗菌肽是昆虫先天免疫系统中非常重要的一类效应分子。昆虫抗菌肽带正电荷,分子量小,大多数少于100个氨基酸残基。根据结构可以将昆虫抗菌肽分为一些不同的家族。昆虫抗菌肽不同的抗菌谱表明,它具有不同的作用机制。以果蝇为模式生物研究表明,昆虫抗菌肽的基因调控涉及到多个信号通路及大量的信号分子。
机械阻断神经管的闭合影响爪蟾神经管辐射状切入及神经嵴细胞定向迁移(英文)
非洲爪蟾 神经管缺陷 神经管闭合 神经嵴 形态发生 细胞切入 背腹图式

2010/1/22
神经管闭合缺陷 (NTDs)是一种严重的先天畸形疾病,在新生儿中有千分之一的发病率。神经管融合前后,多种组织参与形态发生运动。神经管一经融合,神经嵴细胞就会向背侧中线方向产生单极突出并向此方向迁移形成神经管的顶部。与此同时,神经管从腹侧开始发生辐射状切入以实现单层化。在此,我们在非洲爪蟾的移植体中机械阻断神经管的闭合以检测其细胞运动及随后的图式形成。结果显示神经管闭合缺陷的移植体不能形成单层化的神...
