Author Spotlight: In Vitro Hydrogel Model for Glioblastoma Microenvironment Study

Our lab focuses on designing in vitro hydrogel models for glioblastoma steroid encapsulation to mimic the tumor extracellular microenvironment. The effective substrate, mechanical and biochemical properties on steroid cell viability, circularity, stemness, and spreading are investigated with such models. Current experimental challenges in tumor module development revolve around a desire for complexity to mimic all aspects of the tumor microenvironment for physiological relevance, and also a desire for simplicity to make the model accessible, robust, low cost, and easy to use, and compatible with multiplex screening approaches.

We present a protocol that enables fast, robust, and low-cost fabrication of tumor steroids and encapsulation in hydrogels made to mimic the tumor microenvironment. The model does not require any specialized equipment. It will be particularly useful for exploring steroid matrix interactions in building in vitro tissue physiology or pathology models.

Understanding the interactions between glioblastoma cancer cells and their microenvironment can encourage development of new therapies to better treat this cancer. Furthermore, development of an in vitro model for glioblastoma cancer can enhance development of this model for other cancer diseases.
