已知内分泌-旁分泌(EP)细胞,存在于哺乳类的泌尿生殖系统中,最常见的部位是前列腺和尿道。本研究首次证实,在豚鼠精囊腺的分离上皮中存在少量的EP细胞。这些细胞呈黄色甲醛诱发荧光;经L-dopa处理后,则有少量细胞呈绿色或黄绿色荧光。此外,精囊腺EP细胞能被Masson-Fontana银染法着色,但却呈Grimelius银染法阴性。表明精囊腺EP细胞具有亲银细胞或其他旁分泌细胞的特征。
Endocrine-paracrine (EP) cells are known to exist in the urogenital system of mammals, the most common being the prostate and urethra. This study for the first time demonstrates that there is a small amount of EP cells in the isolated epithelium of the seminal vesicle of guinea pigs. These cells were yellow formaldehyde-induced fluorescence; after L-dopa treatment, a small amount of cells were green or yellow-green fluorescence. In addition, seminal vesicle EP cells can be stained with the Masson-Fontana silver stain, but negative in the Grimelius silver stain. Seminal vesicle EP cells showed characteristics of either pro-silver cells or other paracrine cells.
