Effects of the MEK inhibitor (MEKi) PD0325901 (PD) and rhBMP-2 (BMP) treatment on histology in an NF1 open fracture model. Treatment with 10 mg/kg of PD0325901 on days 22 through 10 (PD alone) slightly improved bone volume and callus size. Delivery of 10 mg of rhBMP-2 in the collagen sponge (BMP alone) resulted in a large increase in bone volume and callus size. Combination treatment with local rhBMP-2 and systemic PD0325901 (PD 1 BMP) resulted in further increases in new bone volume and total callus volume.Picro Sirius Red and Alcian Blue staining to assess fibrous tissue.
