    Article Title: Efficient differentiation of human embryonic and induced pluripotent stem cells into functional astrocytes.
    Article Snippet: Human high-grade gliomas (hHGG) remain a therapeutic challenge in neuro-oncology despite current multimodality treatments.. We recently demonstrated that murine embryonic stem cell (mESC)-derived astrocytes conditionally expressing proapoptotic genes can successfully be used to induce apoptosis and tumor shrinkage of hHGG tumor in vitro and in an in vivo mouse model.. The first step in the translation of these results to the clinical settings, however, requires availability of human embryonic stem cells (hESC)and/or induced pluripotent cell (hiPSC)-derived astrocytes engineered to express proapoptotic genes.

    Article Title: “Footprint-Free” Human Induced Pluripotent Stem Cell-Derived Astrocytes for In Vivo Cell-Based Therapy
    Article Snippet: For these experiments, hESC- and hiPSC-derived astrocytes were plated in the top well (5×10 4 cells/well) of 8.0 μm pore size transwell culture dishes (BD Bioscience). .. In the bottom well, culture media or human malignant glioma cells (U87; 5×10 4 cells/well) (American Type Culture Collection) were added and incubated in DMEM+10% serum. ..
