人工智能技术Morphogo系统在骨髓细胞形态学检查的临床应用
Zhongguo shiyan zhenduanxue, 2021 骨髓各系细胞形态学检查是临床检验的重要项目,通常用于某些造血系统或非造血系统疾病的诊断,具有重要的临床应用价值。随着现代医学技术的快速发展以及细胞遗传学、免疫学、分子生物学等技术的普遍应用,为血液病的精准诊断和治疗提供了多种技术手段,但是细胞形态学镜检仍然是血液病诊断中最基础的检查方法和金标准。传统的骨髓细胞形态学镜检存在诸多弊端,

野生动物学报, 2020 本文采用免疫组织化学染色方法，探讨ghrelin在雄性食蟹猴生殖系统内的分布定位。通过对ghrelin免疫阳性细胞在生殖系统中分布部位、含量及细胞形态等方面的研究，为今后ghrelin在食蟹猴体内的功能研究奠定形态学基础。免疫组化染色发现，ghrelin阳性细胞在食蟹猴的生殖系统中有分布。Ghrelin免疫阳性细胞被染为棕色到棕黑色，主要分布于睾丸、附睾及输精管中，精囊腺中无ghrelin阳性细胞分布。Ghrelin阳性细胞在组织中多呈散在分布。细胞大小不一、形态各异，多呈圆形、卵圆形、锥体形 ...

Molecular mechanisms of cell death induced by matrine in human cholangiocarcinoma Cells [PDF]
, 2016 胆管癌是起源于胆管上皮的一种恶性肿瘤，在我国发病率和死亡率逐年上升。而胆管癌细胞抵抗凋亡是导致胆管癌化疗失败的重要原因，所以研发能够诱导胆管癌细胞以不发生凋亡的死亡新途径的化疗药显得十分重要。苦参碱具有多途径、多种机制的抗肿瘤活性，已经证实能够诱导多种肿瘤细胞死亡，但是在胆管癌中的生物学作用和潜在机制却鲜有报道。程序性坏死(necroptosis)是可被调控的程序性细胞死亡，在形态学上具有典型的坏死样形态改变，依赖于受体相互作用蛋白1和3，此外，可被程序性坏死的特异性抑制剂Nec-1所阻断 ...

The Mechanism Study of OVOL2 in Regulation of Epithelial-mesenchymal Transition of Colorectal Carcinoma [PDF]
, 2013 实验背景及研究目的：ovo基因编码一组在进化上从果蝇、线虫、斑马鱼到哺乳动物保守的蛋白家族，包括OVOL1、OVOL2及OVOL3，该蛋白家族是含有4个C2H2锌指结构的转录因子。OVOL3只在胚胎早期表达，目前几乎没有相关研究。尽管现在已有许多关于OVOL1、OVOL2在组织发育方面的研究，但它们在肿瘤发生发展过程中的作用还是完全未知。在这篇文章中，我们致力于发现OVOL2与结直肠癌上皮-间质转化过程之间的关系，深入探究其内在分子机理。 实验方法：划痕 ...
