Table 1.

Means and standard deviations of optical density (OD) of 3 experiments (n = 3 cultures/genotype). Asterisks indicate significant differences between Lox^-/- and wt cells (Alizarin Red eluat of differentiated osteoblasts; p < 0.05; unpaired student's t-test assuming equal variances).

Genotype	Day 14 OD 562 nm [mean ± SD]	Day 21 OD 562 nm [mean ± SD]
Wt	1.156 ± 0.107	1.736 ± 0.134
Lox-/-	0.474 ± 0.066*	0.765 ± 0.087*
