Abstract

To overcome some limitations of in vitro established cell-line tumor models for Hodgkin lymphoma ( HL), we explored whether culturing in a three-dimensional ( 3D) matrix could improve the quality of the model. We used a novel designer peptide based self-organizing matrix. The gene expression profile of the 3D-cultured HL derived cell-line L1236 was compared with that of suspension-cultured ( 2D) L1236, as well as to the gene expression profile found in HL tumor samples. To validate our results we also included a gene expression data set of laser captured Hodgkin-Reed-Sternberg ( H-RS) cells. The gene expression profiles were analyzed using Affymetrix (TM) technology. We found that the 3D culture affected gene expression of a HL derived cell-line inducing a more tumor-related expression profile. 3D culture affected the expression of 500 genes in L1236, upregulating genes involved in immune response and apoptosis and downregulating genes involved in cell division. It also affected genes involved in actin filament polymerization.
