| A cross-section of a construct, grown from surgical specimens of breast cancer, stained for microscopic examination, reveals areas of tumor cells dispersed throughout the non-epithelial cell background. The arrow denotes the foci of breast cancer cells. Links to 1174x766-pixel, 518KB JPG. Credit: Dr. Jeanne Becker, University of South Florida. | Higher magnification of view at left. The arrow points to bead surface indicating breast cancer cells (as noted by the staining of tumor cell intermediate filaments). Links to 1179x771-pixel, 405KB JPG.

| Tumor cells aggregate on microcarrier beads (indicated by arrow). Links to 1171x796-pixel, 271KB JPG. Credit: Dr. Jeanne Becker, University of South Florida. | Higher magnification of view at left, illustrating breast cancer cells with intercellular boundaries on bead surface and aggregates of cells achieving 3-dimensional growth outward from bead.

| B: Outgrowth of cells from duct element in upper right corner cultured
in a standard dish; most cells spontaneously die during early cell divisions,
but a few will establish long-term growth. Links to 1441x1101-pixel, 637KB JPG.

Links to 1476x1141-pixel, 637KB JPG. Credit: Dr. Robert Richmond, NASA/Marshall Space Flight Center. | D: Same long-term growth HMEC, but after 3 weeks in late full-cell contact growth in a continuous culture in a dish. Note attempts to reform duct elements, but this time in two dimensions in a dish rather than in three dimensions in tissue. Links to 1800x1184-pixel, 748KB JPG.
