Figure 3From: Immunohistochemical expression of heat shock protein27 in the mouse dental pulp after immediate teeth separation Weakly positive staining present in some dental pulp cells (a: 30 m-0 m, Bar 20 μm), pulp fibroblasts and capillaries (b: 30 m-3 h, Bar 20 μm). Almost all pulp cells, including pulpal fibroblasts and endothelial cells show strong positive expression (c: 30 m-24 h, Bar 20 μm) and weakly positive in some cells (d: 30 m-1 w, Bar 20 μm).Back to article page
