We have developed a 3-D culture technique for analysing the function of novel genes (Blackshaw et al. 1998), isolated from a cDNA library enriched in upregulated sequences from regenerating Retzius neurons in Hirudo medicinalis (Korneev et al. 1998). We have used this culture system to assay the effects of antisense oligodeoxyribonucleotides to protein 4.1, found in this library, upon microglial cell migration and axonal outgrowth. Protein 4.1 is a structural protein, also implicated in neurotransmitter receptor targeting and RNA maturation.
