The present disclosure relates to methods and compositions for suppressing pathogenic bacterial growth, fungal growth, or microbial growth in or on a selected area of skin or open wound. An area of the skin or open wound having pathogenic bacterial growth, fungal growth, or microbial growth is selected for the suppression of the growth. A suppressing material comprising punicic acid is applied to the selected area of the skin and the pathogenic bacterial growth, fungal growth, or microbial growth is suppressed. Methods of making and using the suppressing material comprising punicic acid are also presently provided.

The present invention provides compositions and methods for wound healing and tissue regeneration. The compositions of the present invention comprise amniotic membrane of the placenta. In certain embodiments, the composition comprises amniotic membrane powder or solubilized amniotic membrane (SAM). In some aspects, the composition is cell-free and rich in cytokines, extracellular matrix proteins, and other components that improve tissue regeneration. In one aspect, the composition is a hydrogel scaffold that comprises amniotic membrane. The present invention reduces contraction and improves blood vessel development in regenerating tissue.

The present disclosure provides compositions with enhanced bioactivity and methods of use in the treatment of disease or tissue injury and pain associated with disease conditions.

A purified exosome product includes spherical or spheroid exosomes with a diameter no greater than 250 nm. In some embodiments, the purified exosome product has a moisture content of no more than 10%. The purified exosome product can be reconstituted to prepare an artificial blood product.

The present invention is related to the field of tissue regeneration. It concerns more particularly new processes, tubes and devices for thrombin, platelet concentrate and wound healant preparations, alone or in combination with cell extracts, cell compositions and uses thereof.

A tissue-derived hydrogel, as well as methods of making and using such hydrogels, are provided.

The present invention provides a composition, comprising: proaccelerin (factor V) and at least one factor selected from the group consisting of: prothrombin (factor II), proconvertin (factor VII), and Stuart-Prower factor (factor X), wherein an amount of the proaccelerin in the composition is between 75% to 750% compared to an amount of proaccelerin in a blood plasma, and wherein an amount of the at least one factor is from 150% to 3000% compared to an amount of the at least one factor in the blood plasma; wherein the amount of proaccelerin and the at least one factor in the composition is determined by extrapolating an observed activity of the composition at a concentration of 500 mM NaCl, using a prothrombin complementation assay using a standard curve constructed using the blood plasma.

The present invention relates to in vitro cultured senescent cells, such as epithelial cells, keratinocytes and/or fibroblasts as well as their use in the treatment of tissue regeneration, particularly for the treatment of wounds such as burns or ulcers or the treatment of inflammatory conditions. Optionally, products may be used in combination with further drugs including antimicrobial or antidiabetic agents.

This invention is in the field of synthesis and amplified photodegradation of hydrogel network and methods of producing and using the same.

Described herein are compositions of collagen and micronized placental tissue components, methods for producing the same and methods for using the same for wound healing, repairing damaged tendons, cosmetic applications and covering biocompatible materials and/or devices.
