Porosity and density of scaffolds. C6-A250—scaffold contains collagen (6000 Da) and alginate (32,000–250,000 Da); C25-A250—scaffold contains collagen (25,000 Da) and alginate (32,000–250,000 Da); C25-A125—scaffold contains collagen (25,000 Da) and alginate (125,000 Da); C25-A63—scaffold contains collagen (25,000 Da) and alginate (63,000 Da); C25-A21—scaffold contains collagen (25,000 Da) and alginate (21,000 Da). Letters “a” indicate that the porosity of all the scaffolds are not significantly different (p ≤ 0.05); letters “b” indicate that the density of all scaffolds are not significantly different (p ≤ 0.05).
