Table 3. The number (%) of genes behaving similarly $\left(\rho >0.7\right)$ and those behaving differently $\left(\rho <-0.7\right)$ out of 3,000 DRGs.

First three rows (block I) compare the trend of 3,000 DRGs under SHH+ with their trend under CTRL, EGF+, and EGF+SHH+, respectively. The latter blocks (II, III, IV) present similar numbers based on comparing the 3,000 DRGs under CTRL, EGF+, and EGF+SHH+ with the same genes under other three conditions.
