The aim of this document is to introduce the reader into the process, through microscopic threedimensional images, of the cellular embryonic deformation of the Drosphila Melanogaster fly through its development. It will also be exposed a program with which it will be possible to calculate the tensions through a code of finite elements from a model of lineal material. In order to carry this study, it will be used the Matlab program, with which a code will be created where the experimental data will be entered and the tension and the deformation of the affected cells will be calculated. The study will be carried through two models: one of them will be a cell-centered model while the other one will be a vertex model. With the pertinent procedures, it will be obtained a series of documents that, when analyzed with a tridimensional visualization tool, will offer a representation of both models and the evolution for each of their meshes. This project will conclude with an appreciation on the efficiency of both two-dimensional and three-dimensional approaches.
