Global Expression intensity map. HeatMap showing upregulation (red) and downregulation (green) of priority 1 and 2 proteins identified as having significant fold changes relative to control. Numbers at bottom of each column indicate days post amputation (dpa). Left column: proteins upregulated on all dpa, or 1 dpa. Middle column: proteins downregulated on 1 and 4 dpa, and upregulated at 7 dpa; proteins upregulated at 1 and 4 dpa and downregulated at 7 dpa; and proteins downregulated at 1 dpa and upregulated at 4 and 7 dpa. Right column: proteins downregulated on all dpa or two of three dpa. Color intensity reflects fold change.
