Abstract
An 8-day-old tissue culture of a human meningioma was studied by EM. Psammoma bodies were detected in all stages of evolution, affording a unique opportunity for observing the genesis of these structures. Matrix vesicles appeared instrumental in the calcification of a granular extracellular material. Although matrix vesicles are described in physiologic and pathologic calcification, they were not previously reported in the very few ultrastructural studies of psammoma bodies in meningiomas.This publication has 4 references indexed in Scilit:
