精子形成

Spermatogenesis

精子形成は、精子が有糸分裂および減数分裂によって雄の始原生殖細胞から産生されるプロセスである。 この経路の初期細胞は精原細胞と呼ばれ、有糸分裂によって一次精母細胞を産生する。 一次精母細胞は減数分裂して2つの二次精母細胞に分けられる。 各2次精母細胞は2つの精子細胞に分裂するにつれ減数分裂を完了する。 これらは精子細胞としても知られる成熟精子に発展する。 したがって、一次精母細胞は、2つの細胞、二次精母細胞、および2つの二次精母細胞の再分化によって4つの精子を産生する。 精子は、多くの性的に再生する生物において成熟した雄性配偶子である。 したがって、精子形成は配偶子形成の男性型である。 哺乳動物では、それは男性精巣および精巣上体において段階的に起こる。 精子形成は、プロセスが正しく起こる最適条件に大きく依存し、性的再生のために不可欠である。 DNAメチル化およびヒストン修飾は、このプロセスの調節に関与している。

Spermatogenesis is the process in which spermatozoa are produced from male primordial germ cells by way of mitosis and meiosis. The initial cells in this pathway are called spermatogonia, which yield primary spermatocytes by mitosis. The primary spermatocyte divides meiotically into two secondary spermatocytes; each secondary spermatocyte then completes meiosis as it divides into two spermatids. These develop into mature spermatozoa, also known as sperm cells. Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce four spermatozoa. Spermatozoa are the mature male gametes in many sexually reproducing organisms. Thus, spermatogenesis is the male version of gametogenesis. In mammals it occurs in the male testes and epididymis in a stepwise fashion. Spermatogenesis is highly dependent upon optimal conditions for the process to occur correctly, and is essential for sexual reproduction. DNA methylation and histone modification have been implicated in the regulation of this process.
