Flow cytometric techniques were used to compare the DNA content, size and viability of meningioma cells obtained directly from surgical specimens with the same cells after a period of culture. Cells isolated from the original meningiomas and cells in primary culture were similar with regard to size and DNA content, regardless of the histologic subclassification of tumor. The cell populations were essentially diploid with a small proportion of tetraploid cells. Viable cells were smaller and more uniform in size than the nonviable cells. An increase in the number of cells having an elevated DNA content was seen with cultures repeatedly transferred. The latter results suggest that any transfer of information from long-term cultured meningioma cells to the in vivo situation must be done with caution.
