Emergence of In Vitro Glioblastoma Survival via Adaptive Quasi-Quiescence by Emulsion Copolymer Matrix

In nature, many organisms enhance their chances of survival by adapting their structures to changing environments. Such adaptation is demonstrated herein, in glioblastoma, via spheroid assembling on the surface of engineered emulsion matrix. Glioblastoma multiforme, the most challenging primary brain malignancy, is characterized by its aggressive nature and poor patient outcomes. This study rationally investigates a novel survival strategy employed by glioblastoma cells through adaptive quasi-quiescence, a dynamic cellular state that enables them to evade therapeutic interventions. A surfactant-free emulsion polymer matrix is engineered to create a biomimetic microenvironment that supports glioblastoma cell survival and adaptation. To the surprise, this state of quasi-quiescence is not only boosted but also can be reversibly adjusted by using the engineered polymer matrix. Utilizing advanced live-cell imaging and in vitro assays, it is demonstrated that this engineered matrix significantly enhances the survival of glioblastoma cells under chemotherapeutic stress conditions. This research provides insights into the survival strategies of glioblastoma paving the way for appreciable therapeutic approaches to improve patients' clinical outcomes.
