title: Modeling Glioma Oncostreams In Vitro: Spatiotemporal Dynamics of their Formation, Stability, and Disassembly

description: Movie 1 of 16 is a supplementary material for the manuscript 'Modeling Glioma Oncostreams In Vitro: Spatiotemporal Dynamics of their Formation, Stability, and Disassembly.' It visually demonstrates the effect of various treatments on the formation and dynamics of oncostreams in high-grade glioma cells. The time-lapse videos provide insightful observations into how various pharmacological drugs influence the initial formation and structural dynamics of oncostreams."

It aims to enhance the understanding of the foundational stages of oncostream formation in glioma cells and their response to various pharmacological treatments, supporting the findings discussed in the manuscript.
