Fig. 4. Median-sagittal section through right two-thirds of mass of angioblasts embryo 22 somites

Median-sagittal section (10 micron) through right two-thirds of mass of angioblasts, to show matting together of cells to form left sinus valve tip. The pulmonary vein is not established. This embryo (22 somites, 44 hours' incubation) is slightly younger than that shown in figure 3. Hematoxylin and eosin stain; series II.
