2. Fig. 1
Flow chart showing the procedure for identifying genes with different expression levels in human cartilage of KBD and the normal. The terms “present,” and “absent” represent expression levels of the transcripts described in Materials and methods. Values are the mean±SD number and percentage of transcripts. See Materials and methods for details of the selection criteria.

Histogram showing levels of expression of eight selected genes, as measured by oligonucleotide array (solid bars: n=4) and real-time quantitative polymerase chain reaction (open bars: n=5).Values are the mean±SD (see Materials and methods for further details).*P<0.05, †P>0.01 for KBD vs the normal, by paired t-test.
