杂交瘤技术的问世使得人们能够对实验性的及人类肿瘤的癌抗原进行广泛与深入地研究,因而使得人们能够识别出许多以往所不能识别的细胞表面分子。然而尽管如此,迄今人们仍不能得到所谓的肿瘤特异性抗原。所揭示的肿瘤抗原或者只是病毒抗原;或者只是肿瘤相关抗原,而后者多为胚抗原 The advent of hybridoma technology has enabled extensive and in-depth research on cancer antigens in both experimental and human tumors, thereby enabling one to identify many cell surface molecules that were not previously recognized. However, so far, people still can not get the so-called tumor-specific antigen. The disclosed tumor antigens are either viral antigens alone or as tumor-associated antigens, whereas the latter are mostly embryonic antigens
