小鼠骨髓细胞染色体标本制备是生物遗传学掌握小动物骨优细胞染色体制备技术的常用方法。在检测环境诱裂剂【则方面有其独特性的优点，已广泛应用于科研和生物实验教学。在多年来的实验教学中我们发现，标本制备的成败与否，首先取决于取材虽，而在实验时由于骨位细胞需反复冲 Preparation of mouse bone marrow cell chromosome specimens is a common method for mastering the chromosomal preparation technology of small animal bone superior cells in the genetics of biology. In the detection of environment cracking agent 【then has its own unique advantages, has been widely used in scientific research and biological experiment teaching. In the years of experimental teaching we found that the success or failure of specimen preparation, first of all depends on the material though, and in the experiment because the bone cells need to be repeatedly washed
