Comparison of Nucleus and Cytoplasm Diameter Buccal Mucosa Cells in Cigarette Smokers Nonsmokers: A Cytomorphometric Study using Feulgen Papanicolaou Stains

We have used size-fractionated, fluorescent dextrans to probe the structure of the cytoplasmic ground substance of living Swiss 3T3 cells by fluorescence recovery after photobleaching and video image processing. The data indicate that the cytoplasm of living cells has a fluid phase viscosity four times greater than water and contains structural barriers that restrict free diffusion of dissolved...
