Abstract

There has been considerable interest in the relationship between hormone‐secreting endocrine cells (HSEC) and their microvessels (MVN) in human pituitary gland. However, microcirculatory networks have rarely been studied in three dimensions (3D). Therefore, this study was designed to visualize and to reveal the relationship between hormone secreting endocrine cells and their microvessel environment including vascular endothelial cells in 3D using rat pituitary glands under various experimental conditions by confocal laser scanning microscopy (CLSM). By CLSM, the 3D distributions of MVN were visualized and revealed a relationship between HSEC and MVN in experimental pituitary glands and human pituitary adenomas. Therefore, 3D reconstructed imaging by CLSM is a useful technique with which to investigate the microvessel environment of hormone‐secreting cells and has the potential to reveal dynamic hormone‐secreting pathways.

BACKGROUND. Tissue factor (TF) was initially identified as an important factor in the initiation of coagulation. TF has recently been found to be expressed highly in certain types of malignant tumors. It has also been reported to be involved in systemic coagulopathy in cancer patients and in the pro

## Background: It is well known that an unbalanced diet induces various changes in the pituitary gland. however, little attention has been paid to the molecular aspects of this perturbation. we studied the influence of a low-protein diet (lpd) on the prolactin (prl) and growth hormone (gh) cells in

Cell-to-cell communication by gap junctions was investigated in the female rat anterior pituitary gland from 10 through 45 days of postnatal development and in 60-day-old animals. Gap junctions initially appeared between adjacent folliculo-stellate cells on day 25. Their appearance in female rats wa
