Cellular morphological parameters of the human urinary bladder (malignant and normal).
The normal and malignant cellular morphological parameters (intra- and extracellular spaces of the human urinary bladder) were obtained from analysis of digital images of bladder histology sections. Then these cellular morphological parameters were compared with the same parameters obtained from the literature for the bladder tissue. However, the limited quantitative data about these parameters available in the literature for bladder cell sizes and other geometrical parameters such as extra-cellular space does not provide a scientific basis to construct accurate structural models of normal and malignant bladder tissue. Therefore, there is usually no quantitative discussion of cell sizes in literature but the measured data in this work can provide a reasonable estimation of expected morphological parameter changes of bladder tissue with pathology. To produce this quantitative information, and also, to build a suitable models in another study using electrical properties of the tissue, 10 digital images of histological sections of normal, and six sections from malignant areas of the human urinary bladder, were chosen randomly (ex vivo). Finally, the measured data showed that there is a significant difference between the cell dimensions (in basal and intermediate layers) of normal and malignant bladder tissues.
