Background: Single cell-based studies represent a promising alternative to conventional molecular approaches in the study of Hodgkin's disease since the malignant Hodgkin and Reed-Sternberg cells (H & RS) represent only a small minority of the cellular infiltrate in affected nodes.

Methods: Single cell polymerase chain reaction (PCR) assays were developed for the analysis of specific genomic DNA sequences and the detection of gene expression. Single H & RS cells were isolated by micromanipulation from cytospin slides or fresh cell suspensions after staining with an anti-CD 30 MoAB.

Results: The status of oncogenes and immune receptor genes was examined by DNA-PCR So far, no IgH or TCR gamma rearrangements were detected in H & RS cells of Tand B-antigen negative classical Hodgkin's cases but were detected in two cases of nodular paragranuloma. Global cDNA amplification was successfully performed from single H & RS cells, and specific gene transcripts were detected with a novel PCR method.

Conclusion: Single cell PCR is a novel and promising method that will help to elucidate many of the open questions in the biology of Hodgkin's disease. In the case of contradictory results, collaborations between different groups utilizing similar approaches have to be performed.
