It is provided a bioadhesive comprising an isolated extracellular matrix (ECM) from a decellularized organ with preserved (ultra) structure comprising laminins, collagen 4, collagen-6, collagen-1, fibronectin, elastin, fibrillin, ECM protein 1, proteoglycans, glycoproteins, biglycan, histidine rich glycoprotein, tenascin, and heparan sulfate proteoglycan 2. The bioadhesive described herein and provided composition can be used to seal intra-operative pulmonary air leaks after lung surgery.

Provided is a bio-adhesive device including an adhesive material layer, an electronic device layer, and a protective film layer to have advantages of being harmless to the human body, being naturally degraded in the body without a separate removal process, and capable of observing the movement of internal organs more closely in real time from outside the body.

The present invention relates to new plasma or new platelet-rich plasma preparations, new cell dissociation methods, new cell associations or compositions, a method of preparation thereof, a use thereof, devices for the preparation thereof and preparations containing such a platelet-rich plasma preparation and cell associations or compositions. Specifically, the invention provides plasma or platelet-rich plasma alone or in cell composition preparations for use in tissue regeneration and bone regeneration and pain reduction.
