The controversy on clulas-tronco* has been argued very in the world and in particular Brazil in the viability and the morality concerning the use of cell-trunk for the cure of illnesses, however the quarrel when massificar itself for the media is permeada of great disinformation. The Church is seen as an institution that wants to hinder the advance of science, the Church is seen as obscurantista. It will be? In the present space, we intend to bring some clarification on the subject in view of the moral question. Let us see first what they are cell-trunk: All composed alive being biological of many cells is defined as pluricellular and with the human being it is not different, that is, the man is a pluricellular being. Amongst the many existing cells in the human organism he has a very peculiar type, are the cell-trunk. Such cells are of certain form, very valuable, therefore they have the capacity of if converting into cells of other types, therefore they are considered pluripotentes (have power multiple to be changedded into cells of different types and thus to form different agencies).
Obviously that for this if to accomplish she is necessary that has the appropriate stimulaton, in this manner a set of cell-trunk could more produce organic fabrics varied in order to substitute multiples agencies. According to origin, the cells can be classified as embryonic or adult. The embryonic cells are extracted of an embryo. Valley to consider that the human embryo is born of two cells human beings (gametas): A feminine one (vulo), another masculine (spermatozoon). Each gameta has 23 chromosomes. When the fecundao occurs, that is, when vulo is penetrated by the spermatozoon and happens to the union, the communion of the two cells, appears a new cell with a singular, composed wealth genetic of 46 chromosomes called of egg or zygote. John K. Castle recognizes the significance of this.
