Figure 6From: Posterolateral inter-transverse lumbar fusion in a mouse modelVolume of spine fusion bone mass as a function of rhBMP-2 dose. A dose–response relationship was observed with consistent bone mass being formed with a dose as low as 0.5 μg of rhBMP-2. Bone volume data for the 10 μg dose (n = 6) is included from the first phase and was consistent with the dose–response trend.Back to article page
