A porcine-cholecyst-derived scaffold for treating full thickness lacerated skin wounds in dogs
In regenerative medicine, despite the chances of graft-rejection, scaffolds prepared from extracellular matrices of various mammalian organs/tissues are widely used. Graft-assisted healing of full thickness skin-wounds is a major use of these bioscaffolds. Therefore, considering its prospective clinical use as a wound healing matrix, this study evaluated the healing potential of porcine cholecyst-derived scaffold (CDS) prepared by a non-detergent/enzymatic method for treating naturally occurring full thickness lacerated wounds in dogs. The CDS caused, in comparison with a commercial-grade bioscaffold prepared out of bovine dermal collagen (BDC), faster healing with respect to the wound healing parameters like peripheral tissue oedema, necrosis (amount and type), indurations, granulation tissue formation and the extent of re-epithelialisation. After 28 days of the treatment, the wound area (mean + SE) reduced from 27.60 ± 8.96 cm2 to 0.19+ 0.18 cm2 and 21.39 ± 5.48 to 6.59 ± 2.60 cm2 in CDS and BDC treated animals, with a reduction in wound sizes by 98.95 ± 2.09% and 54.53 ± 15.90 respectively. By this time, complete wound healing was observed in at least 75% of the former and 25% of the later groups. The CDS was deemed as a candidate bioscaffold for treating full thickness lacerated skin wounds in dogs.
