Accelerating full thickness wound healing using collagen sponge of mrigal fish (Cirrhinus cirrhosus) scale origin.

The potentiality of collagen sponge as a skin substitute, derived from mrigal (Cirrhinus cirrhosus) scale has been explored in this study. Acid soluble collagen (ASC) and pepsin soluble collagen (PSC) from the scale of mrigal were isolated and characterized. The yields of ASC and PSC were ∼3% and ∼7% based on the dry weight of scale while the hydroxyproline content was ∼90mg/g.

Investigating the potential of human placenta-derived extracellular matrix sponges coupled with amniotic membrane-derived stem cells for osteochondral tissue engineering.

Osteochondral injuries are challenging to repair due to their complex tissue anatomy and restricted self-repairing ability associated with a limited blood supply. Osteochondral tissue engineering is an important clinical aspect of the management and treatment of cartilage and underlying bone. In the present study, we fabricated human placenta-derived extracellular matrix sponges (PEMS) for repair of osteochondral tissue through a decellularization process.
