自Ｃｒｕｚ首次提出庆大霉素中毒后小鸡听毛细胞可以再生以来，国外学者围绕这一问题进行了深入研究，进而得到了氚标胸腺嘧啶核苷ＤＮＡ示踪技术的直接证实。但基底膜损害区域毛细胞能否完全再生，至今仍不十分清楚。一般认为毛细胞的再生程度取决于基底乳头的病变程度。为此
Since Cruz first proposed gentamicin poisoning chickens can hear hair cells to regenerate since the foreign scholars have conducted an in-depth study on this issue, and then obtained a direct confirmation of tritium thymidine DNA tracer technology. However, the basement membrane damaged area hair cells can be completely regenerated, is still not very clear. It is generally believed that the degree of hair cell regeneration depends on the degree of papillary lesions. to this end
