Abstract
Purpose: It was presented that mesenchymal stem cells (MSCs) can be isolated from western glioma specimens. However, whether MSCs exist in glioma specimens of different ethnicities is unknown. To verify the existence of MSCs in an independent cohort, we undertook studies to isolate MSCs from a group of Korean patients. We hypothesized that cells resembling MSCs that were deemed mesenchymal stemlike cells (MSLCs) exist in an independent cohort of Korean gliomas. Methods: We cultured fresh glioma specimens using the protocols used for culturing MSCs. The cultured cells were analyzed with fluorescence-activated cell sorting (FACS) for surface markers associated with MSCs. Cultured cells were exposed to mesenchymal differentiation conditions. To presume possible locations of MSLCs in the glioma, sections of glioma were analyzed by immunofluorescent labeling for CD105, CD31, and NG2. Results: From nine of 31 glioma specimens, we isolated cells resembling MSCs, which were deemed Korean glioma stroma MSLCs (KGS-MSLCs). KGS-MSLCs were spindle shaped and adherent to plastic. KGS-MSLCs had similar surface markers to MSCs (CD105 + , CD90 + , CD73 + , and CD45 - ). KGS-MSLCs were capable of mesenchymal differentiation and might be located around endothelial cells, pericytes, and in a disorganized perivascular area inside glioma stroma. Conclusions: We found that cells resembling MSCs indeed exist in an independent cohort of glioma patients, as presented in western populations. We could presume that the possible location of KGS-MSLCs was in perivascular area or in glioma stroma that was a disorganized vascular niche. It might be possible that KGS-MSLCs could be one of constituent of stroma of glioma microenvironment.
