[Renal fusion in embryonic period].

In the present communication we present eight human embryos, understood between the 16 and 30 mm., carrier of renal half fusion -kidney in horseshoe-. We carry out a descriptive study based on fifty embryos of these stadiums (Collection Jiménez Collado), in order to establish the different normodifferenciative stadiums, as well as the possible schedule in which the malformation settles down, for finally to suggest possible mechanism-hypothesis that explain the presence of the renal half fusion.

[Angiogenesis and heart vasculogenesis].

The first sketch of coronary arterial vascularization settles down in human embryos of the stadium 14 of O'Rahilly starting from endothelial islands that contain dense eritoblastes formations that don't present connection with the cavity ventricular willing subepicardial. The presence of this primitive plexus is in intimate dependence with the Jelly acellular of Davies and not with the increase and structuring of the myocardium. Each coronary artery is developed starting from two anlages: one distal that makes it starting from the net subepicardial, and another proximal coming from the evagination of the endocardium of the breasts Valsalva. The final period of the process of coalition of both anlages, and consequently the coronary vascular pattern's determination, it is established in the stadium 20 of O'Rahilly.
