Bone regeneration in a rat cranial defect with delivery of PEI-condensed plasmid DNA encoding for bone morphogenetic protein-4 (BMP-4)

Various Dosages of BMP-2 for Management of Massive Bone Defect in Sprague Dawley Rat

Introduction: The use of BMP-2 plays an important role in the treatment of extensive bone defect. However, data about the optimal dosage of BMP-2 in the massive bone defect cases is rare. Material and Method: Twenty-five SD rats were randomly divided into a control group ofhydroxyapatite (HA) alone (Group I), HA+BMP-2 1µg/mL (Group II), HA+BMP-2 5 ug/mL (Group III), HA+BMP-2 10 µg/mL (Gro...

Bone Morphogenetic Protein-4 and Bone Morphogenetic Protein Receptors Expressions in the Adult Rat Eye

We investigated the expressions of bone morphogenetic protein-4 (BMP4) and its receptors, bone morphogenetic protein receptor IA (BMPRIA), bone morphogenetic protein receptor IB (BMPRIB) and bone morphogenetic protein receptor II (BMPRII) in the adult rat eye. Interesting differences in expression profile were observed between BMPRIA and BMPRIB in the retina. BMPRIA-like immunoreactivity (IR) w...

Atlas of Genetics and Cytogenetics in Oncology and Haematology BMP 4 ( bone morphogenetic protein 4 )

Gremlin1 preferentially binds to bone morphogenetic protein-2 (BMP-2) and BMP-4 over BMP-7.

Gremlin (Grem1) is a member of the DAN family of secreted bone morphogenetic protein (BMP) antagonists. Bone morphogenetic protein-7 (BMP-7) mediates protective effects during renal fibrosis associated with diabetes and other renal diseases. The pathogenic mechanism of Grem1 during diabetic nephropathy (DN) has been suggested to be binding and inhibition of BMP-7. However, the precise interacti...

Bone morphogenetic protein-4 (BMP-4) acts during gastrula stages to cause ventralization of Xenopus embryos.

Injection of RNA encoding BMP-4 into the early Xenopus embryo suppresses formation of dorsal and anterior cell types. To understand this phenomenon, it is necessary to know the stage at which BMP-4 acts. In this paper, we present three lines of evidence showing that BMP-4 misexpression has no effect on the initial steps of mesoderm induction, either dorsal or ventral, but instead causes ventral...
