Cell viability and morphology of BMSCs encapsulated in ((a1) ×200; (a2) ×400) RADA16 hydrogel and ((b1) ×200; (b2) ×400) LN-NS hydrogel after 3 days and 7 days of culture. Stained with calcein-am/PI, the live cells had green fluorescence and the dead and dying cells showed red fluorescence. Some cells encapsulated in LN-NS showed triangular or polygonal morphology at day 3 (arrow), but most cells in the two peptide hydrogels showed similar cell morphology after 7 days of culture.
