Exocytosis from rat adenohypophyseal cells, probably somatotrophic, was studied in the scanning electron microscope after freeze fracturation of the glands. This technique permitted the distinguishing of a clearly delimited exoplasm interrupted by the passage of the secretory granules. It was postulated that the exoplasm could be involved in the control of the release of secretory granules in the endocrine cells studied. At the basal cell surface a simultaneous discharge of several secretory granules has been detected.
在对大鼠腺垂体细胞（可能是生长激素细胞）进行腺体冷冻断裂后，利用扫描电子显微镜对其胞吐作用进行了研究。这项技术能够区分出被分泌颗粒通道中断的界限清晰的外质。据推测，在所研究的内分泌细胞中，外质可能参与了分泌颗粒释放的控制。在细胞基底表面已检测到几个分泌颗粒同时释放的情况。
