Significant inhibition of spermatogenesis and appearance of antibodies against spermatogenic cells identified by cytotoxicity and immunofluorescence reactions were observed in mice of inbred strains 129/Sv and BALB/c and in albino guinea pigs after syngeneic, allogeneic, and xenogeneic immunization with mouse F9 embryonic carcinoma cells and Freund's complete adjuvant. A similar syngeneic immunization with PYS-2 cells was ineffective. Appropriate absorption experiments confirmed the similarity between the antigens of F9 and spermatogenic cells and the absence of such a similarity with antigens of PYS-2 cells. These results support the hypothesis that the oncofetal F9 antigens represent spermatogenic differentiation antigens and thus play an essential role in spermatogenic cell differentiation.
在用小鼠F9胚胎癌细胞和弗氏完全佐剂进行同基因、异基因和异种免疫后,在近交系129/Sv和BALB/c小鼠以及白化豚鼠中观察到精子发生受到显著抑制,并且通过细胞毒性和免疫荧光反应鉴定出针对生精细胞的抗体出现。用PYS-2细胞进行类似的同基因免疫则无效。适当的吸收实验证实了F9抗原与生精细胞抗原之间的相似性,以及与PYS-2细胞抗原不存在这种相似性。这些结果支持了这样的假设,即癌胚F9抗原代表生精分化抗原,因此在生精细胞分化中起重要作用。
