BMP peptides and methods of use
The invention relates to truncated growth factors and variants thereof. The invention also relates to methods of making and using the truncated growth factors. The invention further relates to compositions including a protease and a growth factor comprising a bone morphogenic protein (BMP) or a variant thereof. The invention also relates to methods of using the composition.
1. A method of promoting differentiation of cells into osteoblasts or chondrocytes, the method comprising treating the cells with a peptide consisting of the amino acid sequence of SEQ ID NO: 19.
2. The method of claim 1 , wherein the cells are progenitor cells or adult stem cells.
3. The method of claim 2 , wherein the progenitor cells or the adult stem cells are derived from placenta, bone marrow, adipose tissue, blood vessel, amniotic fluid, synovial fluid, synovial membrane, pericardium, periosteum, dura, peripheral blood, umbilical blood, menstrual blood, baby teeth, nucleus pulposus, brain, skin, hair follicle, intestinal crypt, neural tissue, or muscle.
4. The method of claim 1 , wherein the cells are induced pluripotent stem cells.
5. A method of promoting osteogenesis of cells in a tissue, the method comprising treating the tissue with
a peptide consisting of the amino acid sequence of SEQ ID NO: 19.
6. The method of claim 5 , wherein the osteogenic activity of cells in the treated tissue is greater than the osteogenic activity of cells in untreated tissue.
7. The method of claim 5 , wherein the tissue is bone tissue or connective tissue.
