Graphic representation of Table 5. LGs were injected with IL-1 or saline (vehicle control) and collected at day 1, 2, 3, 7, or 21 after injection for RNA extraction. Levels of Runx1, Runx2, Runx3, Krt5, RBM3, and PrL27 and PrS13 mRNAs were determined by qRT-PCR. Increase in Runx1 and Runx3 expression correlates with increase in expression of epithelial progenitor cell marker Krt5, while expression of Runx2 and ubiquitously expressed Rbm3 remains unchanged during regeneration.
