Human breast tumor slices as an alternative approach to cell lines to individualize research for each patientConde, Sandro José; Luvizotto, Renata de Azevedo Melo; de Síbio, Maria Teresa; Nogueira, Célia ReginaEuropean Journal of Cancer Prevention: July 2012 - Volume 21 - Issue 4 - p 333–335 doi: 10.1097/CEJ.0b013e32834dbc42 Short Paper: Breast Cancer Abstract Author Information There are several breast cancer experimental models including cell lines, which are commonly used due to ease of handling and storage. However, the continued propagation of cell lines and distribution among laboratories results in genetic drift and distancing from the in-vivo model. Primary organ culture of breast cancer slices may produce biological responses with high standard deviation for different samples, reflecting the heterogeneity of different tumors. Thus, the organ culture model system offers a new perspective to the results obtained in the cell lines and offers an alternative for studies that seek to individualize treatment for each patient, an increasingly prominent concern in current cancer therapy.
