LAMB2 and neoplasm: Alginate hydrogel alone (Alg) yielded moderate tumor growth with lower %CV (<25%), while the hydrogels comprising tumorigenic ECM components Laminin (Alg–Lam) and HA (Alg–HA) exhibited enhanced tumor growth while maintaining low %CV values (<25% and 15%, respectively) that were less than half that of tumors from saline and BME.
