| 9. | According to the testosterone secretion correspondent to lh stimuli , leydig ' s cells could be divided , at least , into two populations : one can secrete testosterone incrementally after lh stimuli , in which star protein synthesis is necessary by the way so - called an acute regulatory pathway ; in another testosterone secretion did not occur at all with or without lh stimuli , if any , it was beyond the sensitive of rhpa technically . so we can conclude that leydig ' cells are heterogeneous in testosterone secretion , one of them is regulated by lh through the acute regulation pathway , another may have some function in testis other than testosterone secretion regulated by lh 因此可以说明,按照间质细胞对lh刺激的反应,至少可以将其分为两类,一类间质细胞睾酮的分泌量显著增加,其睾酮合成需要star的参与,即所谓的灵敏调节途径,是睾酮分泌的主要途径;另一类间质细胞没有明显的睾酮分泌或者其分泌量低于本试验的探测灵敏度,若有睾酮分泌,其分泌途径与star的表达无关。 |
