Two types of receptors (DDR1 and DDR2) on cell surfaces get turned on when collagen binds to them, which then starts chains of chemical signals inside the cell that control growth and survival.

The Molecular Interaction of Collagen with Cell Receptors for Biological Function

Narrative Review

The study talks generally about how collagen talks to cells, but it never mentions DDR1 or DDR2 receptors or how they turn on MAPK and PI3K/Akt pathways, so we can't say it supports the claim.

Similar Assertions

When collagen touches two special cell sensors called DDR1 and DDR2, they turn on slow, long-lasting signals that tell cells to grow, move, and rebuild tissues.

When collagen activates DDR2 receptors, it starts signals that help build the structural framework around cells, which is important for tissue strength and repair.
