Prolonged Absence

Fine structure of thyroid glands, adrenal glands, and testes from a rare, 25.5-day-old chicken embryo (with patent esophageal entrance), which was made hypophyseoprivic by partial decapitation, was studied to establish if these gland cells could differentiate in the prolonged absence of the hypophysis and other possible factors. Endocrine cells in these glands had all cytoplasmic characteristics usually seen in fully differentiated gland cells but only the thyroid and adrenal gland cells were less developed. These results show that without the hypophysis or other factors from the missing head parts of partial decapitates (such as the epiphysis and hypothalamus) cytodifferentiation can be completed. Also, differentiation was not prevented by theoretically reduced amounts of albumen ingested by the operated embryo.

New Form

Platelet adhesion initiates platelet aggregation and is an important component of the hemostatic process. Since the development of a new form of collagen as a topical hemostatic agent is of both basic and clinical interest, an ultrastructural and hematologic study of the interaction of platelets with the microcrystalline collagen preparation was undertaken.In this study, whole blood anticoagulated with EDTA was used in order to inhibit aggregation and permit study of platelet adhesion to collagen as an isolated event. The microcrystalline collagen was prepared from bovine dermal corium; milling was with sharp blades. The preparation consists of partial hydrochloric acid amine collagen salts and retains much of the fibrillar morphology of native collagen.

Junctional Complexes

Follicular structures, in the rat pituitary, composed of cells joined by junctional complexes and possessing few organelles and few, if any, secretory granules, were first described by Farquhar in 1957. Cells of the same description have since been observed in several species including man. The importance of these cells, however, remains obscure. While studying human pituitary glands, we have observed wide variations in the fine structure of follicular cells which may lead to a better understanding of their morphogenesis and significance.
