Macroscopic scaffold containing amphiphilic peptides encapsulating cells

A macroscopic scaffold comprising amphiphilic peptides and living cells, wherein said peptides have alternating hydrophobic and hydrophilic amino acids comprise multiple KLD subunits, are complementary and structurally compatible, and self-assemble into a beta-sheet macroscopic scaffold;

• and wherein said macroscopic scaffold is formed by the peptides self-assembling to encapsulate the living cells, said cells being present within said macroscopic scaffold in a three-dimensional arrangement.
