染色体着丝粒点(centromericdots,Cd)结构研究从80年代初,Moroi等[1]发现硬皮病患者血清中存在自身抗着丝粒点抗体(ACA),从而建立Cd结构的免疫荧光技术。目前国内外已有近30余篇有关Cd结构的研究报道[2-7]。然而,这部分研究均以体细胞为对象,尚未见正常男性精子染色体Cd结构的 Chromosome centromeric dots (centromericdots, Cd) structure studies From the early 80s, Moroi et al [1] found that patients with scleroderma sera autoantibody anti-centromere antibody (ACA), thus establishing the Cd structure of immunofluorescence technology. At present, there are nearly 30 reports of Cd structure at home and abroad [2-7]. However, in this part of the study, all the somatic cells have not been found in normal male sperm chromosome Cd structure
