Abstract
We have been able to culture acoustic neuroma (AN) tissues by taking small tumor pieces during surgery from the cisternal or, preferably, metal part of the tumor where macroscopic tissue degeneration is not prominent. The AN pieces were transported in culture tubes to our cell laboratory where they were sliced and transferred to culture medium. The AN tissue demands a crude culture suspension containing laminin. We have been successful in culturing 15 successive ANs. The cells have different morphological features with characteristics of type Anthony A and B. Four main cell types were recognized: ameboid microglia-like cells, spindle-shaped cells, racket-shaped cells, and kite-shaped cells. However, no immortal cell line could be established. Some of the cultures were viable for up to 4 months.
