Abstract
The induced proliferative response of the human derived neuroblastoma cell (IMR32), with the cell proliferation mediating factor, is much milder compared to other cell strains, and develops cellular clusters which are characterized by numerous extensions of dendrites. Presuming this phenomenon to be one of the induced neuronal differentiation due to genetic alterations, we preliminary studied to elucidate the changes in gene expression of the IMR32 by mRNA differential display analysis, monitoring polymerase chain reaction (PCR) products by non-gel molecular sieving capillary electrophoresis in linear polyacrylamide solution. The CE fingerprints revealed a number of peaks with differential expression patterns.


Key words: Differential display / RT-PCR / neuroblastoma / cell proliferation / capillary electrophoresis / molecular sieving / linear polyacrylamide.
