The present disclosure concerns a composition for an implantable pharmaceutical composition prepared from components consisting only of calcium sulfate α-hemihydrate in combination with two antibiotics, vancomycin and tobramycin, for the treatment of infection in bone and soft tissue.

The present invention provides a composition comprising fetal cartilage tissue-derived cells and a fetal cartilage tissue-derived extracellular matrix as active ingredients for regenerating a growth plate. The composition for regenerating a growth plate can inhibit bone bridge formation in a growth plate injury region without a scaffold and differentiate to a growth plate cartilage tissue to effectively fill and regenerate the injured region therewith, whereby the regenerated growth plate tissue can recover growth ability. In addition, the composition is compatible with and safe to biological tissues and is characterized by high reproducibility and homogeneity.

Embodiments described herein relate to a method for preparing cultured cells, the method comprising: obtaining kidney tissue from a human subject; mechanically dissociating the tissue; subjecting the tissue to enzymatic digestion; incubating the tissue with media in a cell culture plate to form cultured cells.

A method of treating a chronic wound may comprise applying to the wound a first scaffold comprising an electrospun polymer fiber. The electrospun fiber may comprise a polymer selected from the group consisting of polyglycolic acid, poly(lactide-co-caprolactone), polylactic acid, polycaprolactone, copolymers thereof, and combinations thereof. The first scaffold may have a thickness from about 50 μm to about 1 mm, a length from about 1 cm to about 20 cm, and a width from about 1 cm to about 15 cm. The method may further comprise keeping the first scaffold on the chronic wound for a time period of about 3 days to about 21 days. After the time period passes, the chronic wound may have a decreased planimetric area.

The invention provides compositions featuring chitosan and methods for using such compositions for the local delivery of biologically active agents to an open fracture, complex wound or other site of infection. Advantageously, the degradation and drug elution profiles of the chitosan compositions can be tailored to the needs of particular patients at the point of care (e.g., in a surgical suite, clinic, physician's office, or other clinical setting).
