Multiple layers of epidermal cells. 3D visualization of full model after running for 130000 iterations showing 535 cells forming multiple layers of the epidermis. The model started with 100 cells in a single layer as shown in Figure 3 and proceeded through about three cell divisions. The greenish-yellow plane under the cells represents the basement membrane. Red subcellular elements have an adhesive force term with the basement membrane, while blue subcellular elements indicate the basal cellular state and yellow subcellular elements indicate the suprabasal cellular state.
