The present invention provides a medium additive for promoting production of a paracrine factor in a cell, containing a compound represented by the following formula (I) or a salt thereof:

##STR00001##

wherein each symbol is as defined in the DESCRIPTION.

Sheet structures for regenerating damaged or diseased mammalian tissue that are formed from acellular dermal mammalian tissue. The acellular dermal mammalian tissue includes extracellular matrix (ECM) and a supplemental bioactive component. The supplemental bioactive component can comprise a nucleic acid, such as RNA, and/or a cell, such as an embryonic stem cell. The sheet structures induce angiogenesis and, thereby, regeneration of new mammalian tissue.

A “nanolipogel” is a delivery vehicle including one or more lipid layer surrounding a hydrogel core, which may include an absorbent such as a cyclodextrin or ion-exchange resin. Nanolipogels can be constructed so as to incorporate a variety of different chemical entities that can subsequently be released in a controlled fashion. These different incorporated chemical entities can differ dramatically with respect to size and composition. Nanolipogels have been constructed to contain co-encapsulated proteins as well as small hydrophobic drugs within the interior of the lipid bilayer. Agents incorporated within nanolipogels can be released into the milieu in a controlled fashion, for example, nanolipogels provide a means of achieving simultaneous sustained release of agents that differ widely in chemical composition and molecular weight. Additionally, nanolipogels can favorably modulate biodistribution.

Provided herein are peptide amphiphiles (PAs). In some embodiments, provided herein are PEGylated PAs (e.g. nonionic PAs). In some embodiments, the peptide amphiphiles are assembled into nanofibers. The nanofibers may further comprise a growth factor protein, which may bind to a growth factor binding sequence presented on the nonionic PA. In some embodiments, the nanofibers further comprise a charged peptide amphiphile. The charged peptide amphiphile may be bound to a growth factor protein. Further provided herein are methods of use of the peptide amphiphiles and compositions comprising the same, such as for regenerative therapy.

The present invention provides a method for preparing a bone protein preparation which contains for example growth factors. The present invention also provides a bone protein preparation obtained by the method and paste, putty, pellet, disc, block, granule, osteogenic device or pharmaceutical composition containing said bone protein preparation.

The present disclosure relates generally to methods of treating or preventing a tissue differentiation factor-associated disorder or disease and methods of treating or preventing fibrosis in a subject using tissue differentiation factor related polypeptide (TDFRPs) in combination with an additional agent. The present disclosure also relates to compositions and pharmaceutical compositions comprising the TDFRPs and an additional agent.

Compositions and methods are provided to accelerate and improve wound repair and reconstruction of connective tissue structures, including tendons, by assembly of collagen using liquid crystalline collagen. The compositions and methods can be used to treat various forms of connective tissue injury or to prevent or slow degeneration to vulnerable tendons that are generally refractory to repair.

A synthetic, flexible tissue matrix and methods for repairing hyaline cartilage defects in a joint using the flexible tissue matrix are described. The flexible tissue matrix includes a high molecular weight polycaprolactone polymer entangled with a polysaccharide such as hyaluronic acid. In the methods, autologous bone mesenchymal stem cells are introduced to a joint by a microfracturing technique, and a membrane made of the flexible matrix is applied to the joint. Cartilage which forms in the joint is hyaline cartilage rather than fibrocartilage.
