Volumetric fraction of the cellular component Pa: Estos investigadores demostraron que la regulacion era llevada a cabo por proteinas, y que estas se asociaban eucromatina y heterocromatina ciertas zonas especificas de los genes llamadas regiones reguladoras.

The results from the analysis of the morphological data obtained with the transmission electronic microscopy fundamentally considering those relative to the similar volumetric fractions of cytoplasm, nucleus and those corresponding to the rough endoplasm reticule from the normal as well as irradiated fibroblasts, demonstrated that these cells possessed similar morphological parameters, indicating that the effects produced by the stimulations with infrared laser did not have an inhibiting action, nor an activating one of the cellular activity, situation which would translate in concluding primarily that these cells eucromatina y heterocromatina a cellular function translated to a rate of protein synthesis-secretion practically similar.

In the electronic micrographs obtained from the normal as well as the irradiated fibroblasts Eucromatina y heterocromatina. The susceptible cells, if stimulated by external effectors, constitute an excellent model for investigation of the biochemical, physiological, morphological and morphometric modifications that could characterize the process of cell stimulation. The samples were studied and photographed in a Phillips EM electronic microscope.

It would be pertinent to recall that this effect, a product of the radiation, decreased the area of the irradiated cell to one half, 82 to 40 square microns transforming it in the typical morphology of a “juvenile” fibroblast, making it tempting to suppose that this situation was the translation of a change in the eucromatiba expression modulated by these infrared stimulations.
