The abundance of gonadotropes producing adrenocorticotropin during neonatal development suggests that they may stem from a common stem cell.In addition, N-terminal fragments of the proopiomelanocortin gene are secreted by gonadotropes to stimulate the development and differentiation of prolactin cells. Recently, the coexpression of GH and gonadotropins during the reproductive cycle has been correlated with the augmentation in the gonadotrope population just before ovulation.

gonadotropes 促性腺細胞
reproductive cycle 生殖週期
adrenocorticotropin腎上腺皮質激素
proopiomelanocortin﹐簡寫POMC 嗎啡黑色素皮質素

在新生兒發展期間,豐富的促性腺細胞產生腎上腺皮質激素,
說明著她們可能源自於相同的幹細胞!
另外,在嗎啡黑色素皮質素基因的N末期斷片中,
都由促性腺細胞所分泌的,
來促進催乳激素細胞的發展及區別功能!
近來,在生殖週期間生長激素和促性腺細胞的相互顯現下,
促性腺母體細胞增加正與排卵前相關聯!

在新生兒發展時期,促性腺細胞的充足製造了腎上腺皮質激素,表示它們或許起源於共同的幹細胞。此外,嗎啡黑色素皮質素基因的N極片段是由促性腺細胞所分泌,以刺激乳腺細胞的發展與分化。近來GH以及促性腺激素在生殖週期的共同表現(coexpression),與排卵期前促性腺細胞數量的增加有關。

盡量試試看,希望能接受。

數量眾多的促性腺細胞,在新生兒的發展期間中,即會產生腎上腺皮質激素,此現象即表示這些物質可能源自一般的幹細胞中。此外,嗎啡黑色素皮質素基因的N-端片段,即由促性腺細胞所分泌,以模擬泌乳激素(prolactin)細胞的生長和分化。最近,在複製循環中的GH和腺激素(gonadotropins)的共同特性表現,即跟剛在排卵前的促性腺細胞數量增長有其相關性。
