hCTLA4-Gene-Modified Human Bone Marrow-Derived Mesenchymal Stem Cells (hBMMSCs) Maintain POSTN Secretion to Enhance the Migration Capability of Allogeneic hBMMSCs through the Integrin αvβ3/FAK/ERK Signaling Pathway

POSTN levels in the coculture supernatant. NC hBMMSCs, CTLA4-modified hBMMSCs, POSTN-modified hBMMSCs, or CTLA4+shPOSTN-modified hBMMSCs were cocultured with PBMCs treated with PHA for 72 h, and the coculture supernatant was isolated to detect the POSTN level by ELISA. ELISA was performed using the coculture supernatant isolated from three independent cell treatments. , when compared to NC group; #, when compared to the POSTN group.
