Fig. 6. Retroviral expression of Barx2 in limb bud micromass cultures increases
Col2a1 gene expression. (A) Barx2-retrovirus infection induced
approximately fivefold increase in Col2a1 mRNA relative to control
infections as measured by real time PCR. n, number of experiments.
(B) Expression of HD-BBR-C construct increases collagen II protein expression
in micromass cultures.
