The spiny eel , belonging to Perciformes, Osteichthyes, is a kind of little freshwater fish distributed in Southern China. In 1998, Our lab detected XX/XY differentiated sex chromosomes in this specie with karyotypic analysis, and then with chromosomal binding and SC observation, we identified that its two largest metacentric chromosomes were X, Y sex chromosomes in 1999. X, Y chromosomes differ each other not only in the distribution of heterochromatin but also in their shapes, which make them could be recognized directly under the light-microscope without any banding treatment.

刺鳅，属鲈形目、刺鳅科(Perciformes，Mastacembelidae)，是广泛分布于中国南方的小型淡水鱼类。1998年，我室通过核型分析，首次发现该物种具有明显分化的异形性染色体，其性别决定类型为XX／XY型。1999年，本室通过染色体显带、精母细胞联会复合体观察，再次确认刺鳅染色体组中最大的一对中部着丝粒染色体为X、Y性染色体，两者不仅已经出现结构异染色质分布上的不同，同时在外部形态上也存在明显差异，识别特征鲜明，在光镜观察下无需显带即能清晰辨认性染色体。

MAIN OUTCOME MEASURES: The seeded cells were observed under inverted microscope; at 1, 2, 3 weeks after seeding, the BMSCs were treated with 4% paraformaldehyde and stained with hematoxylin-eosin; The protein content in seeded cells was determined by bicinchoninic acid assay, and the content of DNA was quantified using Hoechst33258 assay at 5, 10, 14 days after culture.

主要观察指标：倒置显微镜下观察细胞形态；于培养1，2，3周采用40 g/L多聚甲醛固定，常规组织切片，苏木精-伊红染色；在培养5，10，14 d用Hoechs33258荧光法定量测定细胞内DNA含量，BCA法测定蛋白质含量。
