The disclosure provides a medical sealant glue capable of promoting wound healing and a preparation method thereof. The medical sealant glue is formed by covalent cross-linking of two components after being physically mixed by a mixing tool, wherein the first component is a nucleophilic component, and the second component is an electrophilic component. The medical sealant glue has a gelation time of 1-10 s, a swelling ratio of 0-100%, a bursting strength of 100-250 mmHg, and a degradation time of 0.5-300 days. The nucleophilic component of the medical sealant glue contains exosome or hyaluronic acid and chitosan, and thus the medical sealant glue not only has the effect of promoting wound healing, but also has antibacterial and anti-infection effects.

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.

The present invention is concerned with a photosynthetic scaffold that delivers oxygen and its uses for tissue engineering and the treatment of ischemia.

The present invention relates to a pharmaceutical composition in form of emulsion or microemulsion and the use thereof as aid during endoscopic procedures in which it is injected in a target tissue in order to form a cushion. More in details, the invention relates to a method for performing an endoscopic procedure, which comprises injecting said pharmaceutical composition in form of emulsion or microemulsion in a target tissue of a patient, in order to form a cushion, which cushion is then optionally subjected to an endoscopic surgical procedure, such as a resection.

Provided are synthetic bone graft substitutes that include bioactive glass and a carrier. Synthetic bone graft substitutes may include bioactive glass, glycerol and polyethylene glycol. Also provided are bone graft substitutes that include collagen and bioactive glass particles. Example bone graft substitutes may include collagen and bioactive glass particles. Other example embodiments may include Type I Bovine Collagen, an angiogenic agent, such as hyaluronic acid, and bioactive glass. Further provided are methods that include administering the present bone graft substitutes to a mammal, e.g., by surgical insertion of the bone graft substitute into the mammal, either alone or in conjunction with one or more implant devices. Further provided are kits that include the present bone grafts.

Provided is tunable biopolymer hydrogel produced from two processed natural polysaccharides for use as a hemostat. If desired, the hydrogel formation can be tuned so that the hydrogel forms within seconds when applied to a tissue lesion. The resulting hydrogel can adhere to tissue and, without swelling, produce hemostasis within seconds after application to tissue of interest. The hydrogel also captures, aggregates and concentrates platelets and red blood cells at the site of the tissue lesion thereby initiating a clotting cascade at the site of the lesion. The hemostat can be used to prevent blood loss during surgical procedures, for example, during brain, spine or other surgical procedures where hemostasis is desirable, and is particularly useful during surgical procedures where swelling of the hemostat (e.g., in the brain or spine) would be detrimental to the subject.

Provided herein is a plasma-supplemented fibrinogen and/or fibrin formulation, method for the preparation and use thereof.
