Abstract: An apparatus, a method for fabricating the apparatus, and a method for cultivation of cells are provided. The apparatus comprises a first chamber for cultivating cells and a surface, supported in the first chamber, for cell cultivation thereon. The surface exhibits one or more fractal features, each fractal feature comprising out-of-plane fractal patterning providing non-planar microtopology for the surface.

Abstract: A method of treating infection and/or inflammation in a subject includes steps of providing a polyester biomaterial comprising diol monomers and at least first carboxylate monomers, wherein the first carboxylate monomers are itaconate; and administering the polyester biomaterial to the subject. The polyester biomaterial can be in the form of a biomimetic, and characterized by hydrolytic degradability. The polyester biomaterial may further include second carboxylate monomers. The biomaterial can be poly(itaconate-co-citrate-co-octanediol).

Abstract: The present invention examines the interaction between an angiopoietin-1 mimetic peptide, QHREDGS (glutamine-histidine-arginine-glutamic acid-aspartic acid-glycine-serine (SEQ ID NO: 1)) immobilized to a collagen-chitosan hydrogel, and murine bone marrow derived macrophages. When macrophages were cultured in the presence of the peptide conjugated to a hydrogel, both pro-inflammatory and anti-inflammatory cytokines were produced, in contrast to the application of soluble peptide which elicited minimal cytokine secretion. This indicates a unique macrophage polarization with covalently immobilized peptide hydrogels, which can be beneficial in the context of the wound microenvironment.

Abstract: The invention provides a composition and pharmaceutical formulation including a peptide immobilized in a hydrogel. Compositions and formulations of the invention are useful in reducing the size, severity or duration of a wound, ameliorating of one or more symptoms associated with a wound without necessarily curing the wound or lessening in the growth or severity of a wound, skin irritation or skin inflammation. Compositions and formulations of the invention are particularly useful in the treatment of skin irritation, skin inflammation, and a wound associated with diabetes, such as a diabetic ulcer.
