Glioblastoma (GBM) is the most common primary brain tumor and has a poor prognosis; as such, there is an urgent need to develop innovative new therapies. Tumoricidal stem cells are an emerging therapy that has the potential to combat limitations of traditional local and systemic chemotherapeutic strategies for GBM by providing a source for high, sustained concentrations of tumoricidal agents locally to the tumor. One major roadblock for tumoricidal stem cell therapy is that the persistence of tumoricidal stem cells injected as a cell suspension into the GBM surgical resection cavity is limited. Polymeric biomaterial scaffolds have been utilized to enhance the delivery of tumoricidal stem cells in the surgical resection cavity and extend their persistence in the brain, ultimately increasing their therapeutic efficacy against GBM. In this review, we examine three main scaffold categories explored for tumoricidal stem cell therapy: microcapsules, hydrogels, and electrospun scaffolds. Furthermore, considering the significant impact of surgery on the brain and recurrent GBM, we survey a brief history of orthotopic models of GBM surgical resection.

Background/objectives: Glioblastoma multiforme (GBM) is the most common high-grade primary brain cancer in adults. Despite efforts to advance treatment, GBM remains treatment resistant and inevitably progresses after first-line therapy. Induced neural stem cell (iNSC) therapy is a promising, personalized cell therapy approach that has been explored to circumvent challenges associated with the current GBM treatment.

Background: Radiotherapy is the primary treatment modality for most head and neck cancers (HNCs). Despite the addition of chemotherapy to radiotherapy to enhance its tumoricidal effects, almost a third of HNC patients suffer from locoregional relapses. Salvage therapy options for such recurrences are limited and often suboptimal, partly owing to divergent tumor and microenvironmental factors underpinning radioresistance.

Survival quality of glioblastoma (GBM) patients remains undesirable despite the aggressive multimodal treatment methods implemented, which are strongly associated with tumor recurrence after surgical resection. Self-renewal and strong tumourigenic capacity of glioblastoma stem cells (GSCs) at the narrow margin of the incision are essential factors driving tumor secondary strikes. Currently, the challenges in treating postoperative residual GSCs are mainly due to the lack of materials for incision and GSCs targeting.

Accumulating evidence demonstrates that the "Warburg effect" that glycolysis is enhanced even in the presence of oxygen existed in hematopoietic malignancies, contributing to extracellular acidosis. G-protein coupled receptor 68 (GPR68), as a proton sensing GPCR responding to extracellular acidosis, is expected to play a critical role in hematopoietic malignancies. In the present study, we found that GPR68 was overexpressed in acute myeloid leukemia (AML) cells, and GPR68 deficiency impaired AML cell survival in vitro and cell engraftment in vivo.

Article Synopsis
- - The study explores how embryonic stem cells (ESCs) interact with tumor cells, revealing a complex relationship but an unclear role in cancer progression.
- - Co-culturing mouse ESCs with pancreatic and melanoma cancer cells showed that ESCs can significantly prevent tumor cell invasion and reduce metastasis in living mice.
- - RNA sequencing highlighted TP53 and related pathways as key players in how ESCs inhibit cancer cell invasion and metastasis, suggesting a possible use of ESCs in cancer treatment.
