Plate 3

12 Mesoderm of the basal ehorion. Most of tl1e cells are fusiform with elongate nuclei containing scattered, finely divided chromatin. Occasional free spherical cells are to he found. Chorionic epithelium to the right with shrinkage space between it and the rnesoderm. X 600.

13 Linearly arranged vells (X) with large nuclei which form protoplasmic strands which might be interpreted as evidence of vasculogencsis. X 600.

14 Cellular detail from the core of a villus illustrating stages (1, 2, 3, 4) in the transformation of typical mesodermal cells into free spherical cells with basic rrytoplzxsm and very vesicular nuclei with prominent nucleoli characteristic of hemoblasts. X 1340.

15 An accumulation of free round cells at the tip of a villus suggestive of the appearance of blood islands. Near the lower border of the picture is a column of mesodermal cells suggestive of angiogenosis. X 600.
