Objective The origin and the nature of the Hodgkin and Reed-Sternberg cell of Hodgkins lymphoma has been attracting a lot of medical researchers engaged in studying it,for its character by scattered large atypical cells residing in a complex admixture of inflammatory cells.Great improvement has been made since a new method of isolation of single H/RS cells from a frozen section had been set up by KUppers in 1994,and many studies have approved of the B-cell derivation of H/RS cell.lt has been reported that H/R-S cells might partly be originated from B-cell in our research before,but at the same time,we also found that only 18.8% of H/RS cells express CD20,31.3% of immunoglobulin heavy chain rearrangement have been revealed.

目的 霍奇金淋巴瘤(Hodgkins lymphoma，HL)由于它的恶性肿瘤细胞—H／RS细胞一般只占肿瘤组织的极少部分(不到1％)，且散在分布在背景细胞间，因此对于H／RS细胞的来源和性质研究一直是人们探索的目标。1994年德国科隆大学Kūppers等发展了一种从冰冻组织切片上用显微操作仪挑取单个H／RS细胞的显微切割方法进行H／RS细胞基因分析后，人们对H／RS细胞来源的研究有了突破性的进展，多数支持B细胞来源。
