Relative gene expression of hACPCs.

<p>Gene expression analyses (a. Notch 1, b. PTHrP, c. BMP-2) were conducted using the comparative ΔΔC_T method and 18s RNA as internal control. * = Significant difference between control and BMP-2 (comparing unloaded to unloaded and loaded to loaded); # = significant difference between unloaded and loaded; $ = significant difference between control unloaded and BMP-2 loaded, (<i>p ≤ 0</i>.<i>05</i>).
