Lipid metabolism of rat adipocytes in culture

Isolated differentiated rat adipocytes embedded in a collagen matrix were maintained in culture for 0, 4 and 14 days. Assessment of viability by either anabolic glucose metabolism or catabolic lipolytic metabolism can be misleading; both types of metabolism should be measured to establish the status of cells. Cells maintained morphological integrity even when not viable as judged by anabolic glucose metabolism.
