Introduction

Bone morphogenetic proteins (BMPs) are members of the TGF-beta superfamily of growth factors and are known to regulate proliferation and expression of the differentiated phenotype of chondrocytes, osteoblasts, and osteoclasts. To investigate the osteoblastic differentiation gene expressions that contribute to BMP-7 dependent ostogenesis, we performed gene expression profiling of BMP-7-treated mouse bone marrow stromal cells.

Methods

D1 cells (mouse bone marrow stromal cells) were cultured in osteogenic differentiation medium (ODM) for 3 days, and then treated with BMP-7 for 24 hr. Total RNA was extracted using Trizol, purified using RNeasy columns. Total RNA was amplified and purified using the Ambion Illumina RNA amplification kit to yield biotinylated cRNA. The data analysis up- and down-regulation developmental processes (anterior/posterior patterning, ectoderm development, embryogenesis, gametogenesis, mesoderm development, other development process, and segment specification) genes expression fold.
