Table 1.

Number of transcripts on average that are 2-fold up- or downregulated in the pre-mineralization or mineralization phase of human osteoblasts *.

Condition	# of Genes UP	# of Genes DOWN
Pre-mineralization phase	155	164
Mineralization phase	166	236
In both phases	10	8

* Experimental procedures and culture conditions of human osteoblasts (SV-HFO) are described in Woeckel et al. [99]. Two-fold change is based on the average expression at the timepoints in the pre-mineralization or mineralization period.
