Abstract: The present disclosure is related to methods of stimulating bone formation for the purpose of improving bone repair, accelerating bone healing, and/or generating now bone in a local region with absent or diminished bone due to injury, disease, or defect, comprising administering a composition comprising ?-catenin mRNA complex to the subject.

Abstract: Disclosed are liposomal formulations and biomimetic proteolipid nanoparticles that possess remarkable properties for targeting compounds of interest to particular mammalian cell and tissue types. Leukocyte-based biomimetic nanoparticles are disclosed that incorporate cell membrane proteins to transfer the natural tropism of leukocytes to the final delivery platform. However, tuning the protein integration can affect the in vivo behavior of these nanoparticles and alter their efficacy. Here it is shown that, while increasing the protein:lipid ratio to a maximum of 1:20 (wt./wt.) maintained the nanoparticle's structural properties, increasing protein content resulted in improved targeting of inflamed endothelium in two different animal models.

Abstract: Methods of inducing cardiomyocytes from induced pluripotent stem cells by contacting induced pluripotent stem cells with silica nanoparticles comprising regulators of canonical Wnt signaling and coated with a biodegradable polymer.

Abstract: Disclosed are trilaminate collagen-based tissue scaffolds that exhibit remarkable morphological mimicry to that of the natural mammalian periosteum tissue they are useful in remodeling. In particular embodiments, periosteum-modeling trizonal membranes for reforming and regrowing human bone tissue are provided that are composed of a first zone of compact collagen, a second layer of collagen-elastin, and a third layer of biomineralized collagen.

Abstract: Disclosed are biocompatible, biodegradable, implantable devices for the controlled release of bioactive molecules. In particular embodiments, nanotechnology-based tunable implants are disclosed for 1) localized delivery of analgesics to treat postoperative pain; 2) sustained delivery of growth factors to promote vascularization; and 3) directing tissue regeneration, including the self-direction of autologous stem cells for organ remodeling.
