SSTR2 and meningioma: Furthermore, we established freshly generated in vitro meningioma models closely reflecting the original patient tumour and confirmed SSTR-2 expression in three meningioma cultures, which marks the first and essential step towards future in vitro experiments (tumour-cell imaging with fluorescently labelled SSTR-2 receptor markers) and in vivo experiments (meningioma identification in a mouse model).
