2. Fig. 1
Relative expression levels of seven types of ECM proteins in human fetal cartilage. EST numbers matched to each type of ECM were summed. EST frequency was then calculated by dividing the EST copy number of each ECM into the total number of ECM ESTs (n=1056). COL, collagens; PG, proteoglycans; MATN1, matrilin 1; SPARC, secreted protein, acidic and rich in cysteine (osteonectin); CRTL1, cartilage link protein 1; FN, fibronectin.

3. Fig. 2
Relative expression levels of nine collagen genes in human fetal cartilage. Relative EST frequency level was calculated by dividing the EST copy number of each collagen gene into the total number of collagen ESTs (n=723).

4. Fig. 3
Relative expression levels of six proteoglycan genes in human fetal cartilage. Relative EST frequency level was calculated by dividing the EST copy number of each proteoglycan gene into the total number of proteoglycan ESTs (n=92). GPC3, glypican 3; DCN, decorin; AGG, aggrecan; PG4, proteoglycan 4; LUM, lumican; SDC2, syndecan 2; FMOD, fibromodulin.
