: Time-lapse footage of cancer cells moving across substrates of varying stiffness.

: This "chemo-mechanical" loop promotes cell proliferation, migration, and the transition of normal cells into invasive cancer cells. Potential Video Content

Based on the full text of the study, supplemental videos (often named with similar codes) typically demonstrate:

The research, published in journals such as and archived on PMC , explores how tissue stiffness and biochemical signaling work together to drive cancer growth. Key Research Findings

: Visual evidence of cell mobility and invasiveness.

: Injured epithelial cells release Sonic Hedgehog (SHH) ligands.

: Observations of "leader cells" responding to GLI2 inhibition.

: This signaling activates fibroblasts, which increase tissue stiffness by producing collagen.
