A) ultra filtrate of plasma to which proteins and proteoglycans (e.g., glycosylated mucoproteins) are added by syntrophoblasts in the lining layers. B) ultra filtrate of plasma to which proteins and proteoglycans (e.g., glycosylated mucoproteins) are added by fibroblast-like synoviocytes in the lining layers. C) ultra filtrate of plasma to which chylomicrons are added by fibroblast-like synoviocytes in the lining layers. D) ultra filtrate of whole blood to which proteins and proteoglycans (e.g., glycosylated mucoproteins) are added by fibroblast-like synoviocytes in the lining layers.
