Why is it important?

ASC and PSC were successfully extracted from the skin of major freshwater carp fish (catla and rohu) cultured in India with comparatively better yields and high quality. These ASC and PSC were characterized as type I collagen with well maintained triple helical structure. ASC and PSC showed similar surface morphology, thermal stability and other biochemical properties. ASC and PSC were exhibited better fibril-forming ability with distinct fibril structure. Thus, collagen skin of catla and rohu could serve as realistic alternative sources of collagen for the potential uses in food, cosmetic and beverage industries as well as in tissue engineering. Results of the study also suggested that the skin of Indian carps (catla and rohu) could be processed together to prepare type I collagen. Overall, the results indicated the feasibility of using the carp skin as a good alternative source of realistic high-quality collagen.
