A cultureware system is directed to maintaining viability of mammalian cells, and includes a disposable holding container having a cell receiver with a cell-receiving surface. The cell receiver consists of a cell-adhesion inducement material including a polystyrene material and a glass material. The system further includes a polytetrafluoroethylene (PTFE) coating lining the cell-adhesion inducement material of the cell-receiving surface, and a culture of adherent mammalian cells located within the cell receiver on the PTFE coating. In response to attachment interaction between the mammalian cells and the PTFE coating, a decreased cell adhesion results in a cell viability rate of at least about 60% to about 70% over a 72-hour culturing period, the cell viability rate being under 90% over the 72-hour culturing period if, in the absence of the PTFE coating, the mammalian cells are located directly on the cell-adhesion inducement material.
