Final results In spite of identical situations, main cultures of glioma stem cells (pGSCs) show unique growth phenotypes ranging from free-floating spheroids to adherent monolayers [53]. In specific, LK7 pGSCs grew in complete NeuroCult stem cell (NSC) medium as an attached monolayer although LK17 pGSCs formed adherent spheroids (Figure 1A) with doubling occasions of about 1.0 (LK17) and 1.7 (LK7) days (Figure 1B,C). Around the mRNA level, LK7 and LK17 cells differed in their abundances of stem-cell markers. While the mRNA encoding the mesenchymal stem-cell marker ALDH1A3 was a lot a lot more abundant in LK7 than in LK17, mRNAs on the stem-cell markers Musashi-1 (MSI1) and Prominin-1 (PRO.
