the effect of cytoplasms on the expression of tumorigenicity was examined in interspecific reconstituted cells and cytoplasmic hybrids ( cybrids ) formed by fusions between karyoplasts ( or intact cells ) from highly tumorigenic mouse melanoma b16 cells and cytoplasts from non-tumorigenic , hypoxanthine-guanine phosphoribosyl-transferase ( hgprt ) -deficient and chloramphenicol ( cap ) -resistant rat myoblastic cells , l6tg x capr .
