Hydrogels have been widely used to mimic the biochemical and mechanical environments of native extracellular matrices for cell culture and tissue engineering. Among them, self-assembling peptide hydrogels are of special interest thanks to their great biocompatibility, designability and convenient preparation procedures. In pioneering studies, self-assembling peptide hydrogels have been used for the culture of bone marrow cells. However, the low mechanical stability of peptide hydrogels seems to be a drawback for these applications, as bone marrow cells prefer hard substrates for osteogenic differentiation. In this work, we explored the use of hydroxyapatite (HAP)-peptide hybrid hydrogels for three-dimensional (... More
