关于人体细胞染色体的研究,由于采用了体外培养外周血液、植物凝集素(PHA)的应用、秋水仙碱的处理、低渗和气干制片等新技术,有了很快的进展。由于对染色体畸变与疾病关系的研究,使我们认识到一些染色体疾病(Chromosomal disease)。对肿瘤细胞的染色体分析,使我们对肿瘤细胞的细胞遗传学特点,有了新的认识。美国的sandbenrg A.A实验室 With regard to human chromosomes, rapid progress has been made in using new technologies such as in vitro culture of peripheral blood, application of phytohemagglutinin (PHA), colchicine treatment, hypotonic and air-dried tablets. Due to the study of the relationship between chromosomal aberrations and diseases, we recognize some chromosomal diseases. Chromosomal analysis of tumor cells gives us a new understanding of the cytogenetic characteristics of tumor cells. American sandbenrg A.A laboratory
