The present invention is directed to the use of the GDF-5 mutant with an amino acid exchange R399E for the treatment of cartilage defects and pain and a pharmacological composition of said GDF-5 mutant.

Provided herein are compositions comprising a composite of peptide amphiphiles and biocompatible particles and methods of use thereof for treatment of bone and/or tissue defects. In particular, compositions comprise a slurry paste of a peptide amphiphile nanofiber solution mixed with solid biocompatible particles, and find use in tissue/bone regeneration, growth factor delivery, and/or cell delivery.

A bone repair material, a preparation method of the bone repair material, and a biological composite scaffold are provided. The bone repair material includes: a base material, and a carbon nanomaterial and a polypeptide both mixed with the base material; and the carbon nanomaterial and the polypeptide are bonded by chemical bonds. The preparation method includes: bonding a carbon nanomaterial with a polypeptide by chemical bonds; and mixing the carbon nanomaterial and the polypeptide bonded by the chemical bonds with a base material, and performing a molding treatment.

The present technology is directed to compositions and methods for preventing, ameliorating, or reducing the severity of one or more signs, or symptoms associated with a reduction of function, decreased expression level of, and/or deficiency in one or more of COL4A3, COL4A4 and COL4A5 genes. Also disclosed herein are methods of preventing or treating Alport Syndrome in a mammalian subject, reducing risk factors associated with Alport Syndrome, and/or reducing the likelihood or severity of Alport Syndrome. The methods comprise administering to the subject an effective amount of an aromatic-cationic peptide.

The invention relates to a polypeptide selected from bone morphogenetic protein 10 (BMP10), or a bone morphogenetic protein 9 (BMP9) variant lacking osteogenic activity, for use in the treatment of a vascular disease or a respiratory disease. The invention also relates to novel BMP9 variants and to pharmaceutical compositions comprising said polypeptides.

In some aspects, disclosed herein are methods and compositions for treatment or prevention of cerebral palsy using fibroblasts or derivatives thereof. Disclosed herein are fibroblasts and derivatives thereof capable of inducing neurogenesis and/or reducing inflammation in a subject. In some cases, the disclosed methods comprise use of conditioned fibroblasts. Fibroblasts may be conditioned with agents capable of enhancing therapeutic efficacy, for example oxytocin and/or human chorionic gonadotrophin (hCG).

The problem that differences among lots in components and amounts of growth factors and the like in platelet-rich plasmas derived from an autologous plasma and the freeze-dried preparations thereof are large, and the effects of the lots are not kept constant is solved.

Specifically, a freeze-dried preparation comprising megakaryocytes and platelets induced to differentiate from stem cells, a pharmaceutical composition comprising the freeze-dried preparation, and the like are provided.

Methods and compositions for rejuvenating skeletal muscle stem cells are disclosed.
