Plain-language verified summary

Question

Not reported in the reviewed source.

Methods

Methods: The functionalized SAP was constituted with self-assembling motif, Tβ4-binding site, and cell adhesive ligand.

Scale or participants

Recent studies have suggested that the epicardium plays an important role in heart development as well as regeneration of the injured myocardium 10.

Key findings

Results: We found that the designer RADA-RPR bound Tβ4 and adhered to EPDCs and that Tβ4 released from the functionalized SAP could effectively activate the epicardium and induce EPDCs to differentiate towards cardiovascular cells as well as lymphatic endothelial cells.

Limitations and uncertainty

Conclusions: These results demonstrate that sustained release of Tβ4 from the functionalized SAP can activate the epicardium and effectively enhance the repair of infarcted myocardium.
