The present disclosure provides compositions, methods, and kits that enable the in situ growth of polymers on or within a subject. In some aspects, the tissue-active monomers, including monomers comprising macromolecules, provide a broad set of material choices for synthetic tissue barriers. In additional aspects, the compositions, methods, and kits are useful for treating or preventing a disease or disorder.

A device that includes a scaffold composition and a bioactive composition with the bioactive composition being incorporated into or coated onto the scaffold composition such that the scaffold composition and/or a bioactive composition controls egress of a resident cell or progeny thereof. The devices mediate active recruitment, modification, and release of host cells from the material.

A method of treating a soft tissue defect in or on the body of a patient is provided. A placental construct for treatment of a disease or condition is also provided. The placental construct includes a therapeutically effective amount of a birth tissue material.

Embodiments herein described provide devices for identifying and collecting rare cells or cells which occur at low frequency in the body of a subject, such as, antigen-specific cells or disease-specific cells. More specifically, the devices are useful for trapping immune cells and the devices contain a physiologically-compatible porous polymer scaffold, a plurality of antigens, and an immune cell-recruiting agent, wherein the plurality of antigens and the immune cell recruiting agent attract and trap the immune cell in the device. Also provided are pharmaceutical compositions, kits, and packages containing such devices. Additional embodiments relate to methods for making the devices, compositions, and kits/packages. Further embodiments relate to methods for using the devices, compositions, and/or kits in the diagnosis or therapy of diseases such as autoimmune diseases or cancers.

The present disclosure provides compositions, methods, and kits that enable the in situ growth of polymers on or within a subject. In some aspects, the monomer, dopamine, polymerizes in vivo to form a polymer on a tissue. In additional aspects, the compositions, methods, and kits are useful for treating or preventing a disease or disorder.

In various embodiments, the present invention describes materials and methods for the local reprogramming of cells in a location where the treatment is applied. The invention can be used to replace lost cells or to restore function to tissue damaged due to disease, injury or genetic defect. In various embodiments, the treatment includes a semisolid hydrogel embedded with liposomes. The liposomes can contain an effector molecule or molecules. When phagocytic cells such as monocytes infiltrate the hydrogel, they encounter the liposomes and incorporate the liposomes carrying the effector molecules into the cells. In some embodiments, the effector molecules can induce angiogenesis. The matrix can contain other effector molecules designed to attract specific cells to the matrix. The cells can also remain in the matrix and secret molecules such as proteins and hormones that will diffuse through the matrix material to the surrounding tissue.

Provided herein is a method for storing an emulsion-adjuvanted vaccine in a medical injection device having a lubricant coating, said method including the steps of: (a) providing a medical injection device having a barrel having an inner surface; (b) forming a silicone oil layer on at least a part of the inner surface of the barrel that is intended to be in contact with the vaccine; (c) carrying out an oxidizing plasma treatment of the layer so as to crosslink at least part of the silicone oil layer and form a lubricant coating; and (d) filling the barrel with the emulsion-adjuvanted vaccine. The invention also relates to a medical injection device obtained directly from this method and to the use of plasma-treated silicone oil as a lubricant coating.
