W, Wound; C, Control; N/A, not applicable; −, no staining (<5%); +, minimal staining (<25%); ++, moderate staining (25% to 50%); +++, strong staining (>50%). Peak expression time points for a given tissue component are highlighted for wounded E16 (bold) and E19 (underlined) animals.
*In general, non-wounded control skin and E16-wounded fetuses contained very few inflammatory cells. The chart reflects the intensity of intracellular TGF-β staining and not the actual number of inflammatory cells present.
