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

<p>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."</p> <p>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.</p> <p>Individual Movie Descriptions:</p> <p><strong>Movie 1: Low Density Oncostream Dynamics: </strong>Demonstrates the formation and dynamics of oncostreams in GFP+ NPA glioma cells at low seeding density (1 &times; 10^5 cells), over 24 hours using time-lapse confocal imaging.</p> <p><strong>Movie 2: High Density Oncostream Dynamics:</strong> Explores the effect of high cell seeding density (2 &times; 10^5 cells) on the formation and behavior of oncostreams in GFP+ NPA glioma cells, analyzed over 24 hours.</p> <p><strong>Movie 3: Spatiotemporal Progression of Oncostreams:</strong> Showcases the sequential self-formation and developmental stages of oncostreams over a 24-hour period.</p> <p><strong>Movie 4: Collagenase Impact on Oncostreams:</strong> Description: Illustrates the disassembly of aggressive and malignant oncostreams with 15 U/ml collagenase treatment over 15 hours.</p> <p><strong>Movie 5: TC-I-15 Inhibition of Oncostream Formation:</strong> Details the impact of TC-I-15, an integrin antagonist, on adhesion and oncostream formation in glioma cells, recorded over 20 hours.</p> <p><strong>Movie 6: Cytochalasin D Disruption of Oncostreams:</strong> Captures the effect of Cytochalasin D on oncostream formation by inhibiting actin polymerization, observed over a 1-hour period with rapid imaging intervals.</p> <p><strong>Movie 7: Myosin II Inhibition in Oncostreams with p-nitro Blebbistatin: </strong>Presents the influence of p-nitro Blebbistatin on oncostream formation by inhibiting myosin II, documented over 1 hour with dynamic cellular responses.</p> <p><strong>Movie 8: Control - Oncostream Formation without BAPTA-AM:</strong> Demonstrates oncostream formation and dynamics without BAPTA-AM treatment, monitored over 16 hours.</p> <p><strong>Movie 9: BAPTA-AM (Calcium Modulation) Impact on Oncostream Formation:</strong> Reveals the effects of BAPTA-AM treatment on oncostream dynamics, observed over a 16-hour period.</p> <p><strong>Movie 10: Glutamate Influence on Oncostreams:</strong> Shows the effects of glutamate treatment on oncostream formation and dynamics, monitored over 16 hours.</p> <p><strong>Movie 11: Histamine Impact on Oncostream Dynamics:</strong> Demonstrates the influence of histamine on the formation and behavior of oncostreams, captured over a 16-hour period.</p> <p><strong>Movie 12: Oncostream Formation on Non-Laminin Coated Surfaces:</strong> Illustrates the compromised organization of oncostreams on poly-D-lysine coated dishes without laminin, observed over 45 hours.</p> <p><strong>Movie 13: 4-HAP Treatment Effect on Oncostreams:</strong> Shows the impact of 4-HAP treatment on the structure of oncostreams, monitored over 20 hours.</p> <p><strong>Movie 14: Rho-Activator I Untreated Control:</strong> Presents the formation and dynamics of oncostreams without Rho-Activator I treatment, recorded over 16 hours.</p> <p><strong>Movie 15: Rho-Activator I Influence on Oncostreams Dynamics:</strong> Details the effects of Rho-Activator I on oncostream formation and dynamics, observed over a 16-hour period.</p> <p><strong>Movie 16: Rho-Inhibitor Effect on Oncostreams Dynamics:</strong> Demonstrates the impact of Rho-Inhibitor on the formation and behavior of oncostreams, monitored over 16 hours.</p>
