Manually microdissected embryonic tibiae; zone I of the growth plate

Mus musculus |
| Characteristics |
Tibiae derived from four litters of CD1 mice (Charles River) staged at embryonic day E15.5 were isolated and manually separated into three segments corresponding to early, middle and
late chondrocyte differentiation (Figure 3.1 A, left panel); each litter represented one independent experiment. Starting at either extremity, the region corresponding to approximately the first
third of the bone was segmented and designated zone I, which contains both proliferating and resting cells. Zone II includes segments corresponding to the central region, starting from each
end of the bone and contains mostly prehypertrophic and early hypertrophic chondrocytes. The final zone, zone III, constitutes both the most mature hypertrophic chondrocytes and
the mineralized portion of the tibiae.

| Data processing |
Microarray data was pre-processed using the GC (guanine and cytosine) Robust Multi-chip Averaging (RMA) algorithm in Genespring GX*.
Expression values were further filtered by retaining only those probe sets with expression values of at least 50 in at least 25% of all conditions, thus generating a list of 22 497 probe sets.
Subsequent zone comparisons from the microdissected tibiae data set (MD) were filtered using a 1.5-fold change threshold that produced lists of 6185, 8134 and 7220 probe sets for the zone I vs. II, II vs. III and zone I vs. III, respectively.
The same data set was also normalized in parallel using RMA using RMAEXPRESS software v.0.4.1 developed by B. Bolstad, University of California, Berkeley (Bolstad et al., 2003).
Background adjustment and quantile normalization parameters were selected for data processing.
