Note that in case of Azan trichrome stain and immunohistochemical detection of type I collagen, type III collagen and type IV collagen all cells were counted, whereas in case of cluster of differentiation (CD)34, CD68, Ki-67, laminin, matrix metalloproteinase (MMP)-2, MMP-9, tenomodulin and type I procollagen only immunopositive cells were counted.
