Outline of Final Research Achievements |
We generate cell-free 3D matrices from PSCs. The cell-free 3D matrices containing abundant fibronectin and collagen fibers closely resembled in vivo stromal matrices. To assess the impact of hypoxia on ECM organization, we measured fibronectin fiber orientation in 3D matrices derived from PSCs. We found that 3D matrices from PSCs under hypoxia displayed an organized parallel fibronectin orientation compared with random fiber arrangement in the 3D matrices derived from PSCs under normoxia. Cancer cells movement within 3D matrices derived from PSCs under hypoxia was directionally persistent. PLOD2 in PSCs was the gene that potentially regulates ECM fiber architecture under hypoxia. Knockdown of PLOD2 in PSCs blocked parallel fiber architecture of 3D matrices, leading to decreased directional migration of cancer cells within the matrices.
