利用增殖细胞核抗原（ＰＣＮＡ）免疫组织化学染色（ＳＡＢＣ法），显示庆大霉素损伤后小鸡基底乳头毛细胞再生中的增殖细胞。结果：庆大霉素组出现散在的ＰＣＮＡ阳性的增殖细胞核；正常对照组和阴性对照均为阴性。提示ＰＣＮＡＳＡＢＣ法染色是显示增殖细胞的理想方法之一。
Using proliferating cell nuclear antigen (PCNA) immunohistochemical staining (SABC method), proliferating cells in chick basement nipple hair cell regeneration after gentamicin injury were shown. Results: Scattered PCNA positive proliferating cell nuclei were observed in the gentamicin group. The normal control group and the negative control were negative. Tip PCNASABC staining is one of the ideal method to display proliferating cells.
