Results In spite of identical situations, major cultures of glioma stem cells (pGSCs) show diverse growth phenotypes ranging from free-floating spheroids to adherent monolayers [53]. In specific, LK7 pGSCs grew in full NeuroCult stem cell (NSC) medium as an attached monolayer while LK17 pGSCs formed adherent spheroids (Figure 1A) with doubling occasions of about 1.0 (LK17) and 1.7 (LK7) days (Figure 1B,C). On the mRNA level, LK7 and LK17 cells differed in their abundances of stem-cell markers. Although the mRNA encoding the mesenchymal stem-cell marker ALDH1A3 was substantially more abundant in LK7 than in LK17, mRNAs of your stem-cell markers Musashi-1 (MSI1) and Prominin-1 (PRO.
