Injectable, biodegradable scaffolds are required for soft tissue reconstruction owing to its minimallyinvasive approach. Such a scaffold can mimic the native extracellular matrix (ECM), provide uniformdistribution of cells and overcome limitations like donor site morbidity, volume loss, etc. So, here wereport two classes of biocompatible and biodegradable hydrogel blend systems namely, Alginate/O-carboxymethyl chitosan (O-CMC) and Alginate/poly (vinyl alcohol) (PVA) with the inclusion of fibrinnanoparticles in each. The hydrogels were prepared by ionic cross-linking method. The developed hydro-gels were compared in terms of its swelling ratio, degradation profile, compressive strength and elasticmoduli. From these preliminary findings, it was concluded that Alginate/O-CMC formed a better blendfor tissue engineering applications. The potential of the formed hydrogel as an injectable scaffold wasrevealed by the survival of adipose derived stem cells (ADSCs) on the scaffold by its adhesion, prolif-eration and differentiation into adipocytes. Cell differentiation studies of fibrin incorporated hydrogelscaffolds showed better differentiation was confirmed by Oil Red O staining technique. These injectablegels have potential in soft tissue regeneration.
