Organotypic Culture of Breast Tumor Explants as a Multicellular System for the Screening of Natural Compounds with Antineoplastic Potential

<div>Nuclear expression of the cell proliferation marker Ki 67 in cultures of breast cancer explants. Representative images showing that over 40% of the neoplastic cells express Ki 67 at all-time points. The proliferation index is considered “high” when &gt;20% of the cells are positive for this marker. (a) Normal breast tissue (negative control); (b) breast tumor (positive control); (c), (d), and (e) breast tumor explants cultured for 24, 48, and 72 h, respectively. Immunohistochemical staining (10x).</div>
