RESUMEN
<p><b>OBJECTIVE</b>To investigate the primary culture of mammary epithelial cells derived from human breast hypertrophy.</p><p><b>METHODS</b>Mammary epithelial cells of human breast hypertrophy were isolated and cultured by the collagenase digestion method. The morphology observation and identification of the cultured cells were performed by inverted microscope observation, HE staining and cytokeratin immunohistochemical staining.</p><p><b>RESULTS</b>Most of the cultured cells were pebbles-like or polygon under the inverted microscopy. Some had irregular form. They had typical island-like appearance during multiplication with close connection between the cells. The HE staining results showed the cytoplasm was stained pink or lilac, the nucleus was stained bluish violet and was round or oval in shape, with clearly visible chromosomes in dark blue. The cytokeratin immunohistochemical staining demonstrated the tissue-specific expression of cytokeratin 18 in epithelial cells by the cytoplasm stained claybank.</p><p><b>CONCLUSION</b>High purity of primary mammary epithelial cells derived from human breast hypertrophy can be obtained by the collagenase digestion method and conditioned medium.</p>

<p><b>OBJECTIVE</b>To investigate the method and efficacy of reduction mammaplasty with central gland pedicle based on Würinger' s horizontal septum in the treatment of female breast hypertrophy.</p><p><b>METHODS</b>From Mar. 2009 to Sept. 2011, a series of 21 consecutive patients with mild and moderate hypermastia underwent reduction mammaplasty with central gland pedicle. Only the mammary gland located at cranial portion of septum was resected and the mammary gland located at caudal portion of septum was preserved.</p><p><b>RESULTS</b>In our series, the mean resection weight per breast was (327.8 +/- 148.6) g, the mean nipple-to clavicle midpoint was 20.0 cm (range, 18.0-22.0 cm) and the mean nipple-to-sternal-notch distance was 21.0 cm (range, 19.5-22.5 cm) postoperatively. Nipple was moved upward 6.5 cm on average (range, 4.0-10.0 cm). There was no hematoma and nipple-areolar complex (NAC) necrosis. Minimal wound dehiscence occurred in one case and healed by dressing change. 17 cases were followed up for 3 months to 2 years. Satisfactory breast shape was achieved with good NAC sensibility.</p><p><b>CONCLUSIONS</b>The reduction mammaplasty with central gland pedicle based on Würinger' s horizontal septum is a safe and reliable technique for mild and moderate hypermastia. Satisfactory breast contour, as well as NAC viability and sensibility, could be achieved with lower occurrence of hematoma or seroma.</p>

<p><b>OBJECTIVE</b>To investigate the therapeutic effect of glandular flap combined with dermal flap suspension for correction of mild and moderate breast ptosis.</p><p><b>METHODS</b>The dermal flap was formed according to the breast ptosis and dissection was performed between the skin and gland. The superior-lateral gland was partially resected or cut vertically only to form the lateral glandular flap. Then the glandular flap was rotated medially and fixed to shrink the glandular base area. Then the breast was up-positioned and fixed with dermal flap to remodel the breast shape.</p><p><b>RESULTS</b>From Mar. 2006 to Mar. 2010, 46 cases were treated with satisfactory result. There was no severe complication, except for 2 cases of unilateral hematoma. 40 cases were followed up for 6 months to 4 years with good breast shape. No secondary ptosis, breast flatten and NAC sensation disorder was happened.</p><p><b>CONCLUSIONS</b>Glandular flap combined with dermal flap suspension is a good method for mild and moderate breast ptosis with reliable long-term results. The breasts have busty appearance and good projection with inconspicuous scar.</p>
