Two EST(One come from hemin induced HEL cells while the other come from PMA induced HEL cells) were chosen as the probes for cDNA library screening and several full length cDNA clones were isolated from human bone marrow cDNA library.

• 选择两个新EST筛选人骨髓细胞cDNA文库，获得两个新的锌指蛋白编码基因的全长cDNA，分别命名为HZF1(其EST来源于被hemin诱导的HEL细胞)和HZF2(其EST来源于被PMA诱导的HEL细胞)。
