Can breast nipple fluid collected with automated aspiration and preserved in based-liquid solution improve the cytological samples?
The results discussed here encouraged us to use samples collected automatically in routine procedures.
Fibroblast MMP-1 was most likely responsible for collagen dissolution in the culture model, while cathepsin B may have been part of an activation pathway. All studied proteinases contribute to extracellular matrix destruction in inflamed gingival tissue, where they probably activate each other in proteolytic cascades.
