哺乳动物的性腺由生殖细胞和体细胞共同形成,性别决定前的性腺具有双向分化的潜能,性腺中体细胞的分化决定 其发育为睾丸或卵巢。这一分化过程受到多种因子的精细调控。其中SRYSOX9SOX3SOX8SOX10FGF9/ FGFR2PGD2AMHDMRT1等参与睾丸的发育和分化,而FOXL2CTNNB1RSPO1WNT4FollistatinERα/β和 BMP2则在卵巢发育过程中发挥关键作用。如果这些分子调控网络受到内源性或外源性因子的破坏,则会引起两性发育紊 乱,甚至导致雄性向雌性或雌性向雄性的性别逆转。本文以小鼠模型为例,阐述了在性别决定过程中体细胞命运决定以及 谱系分化的分子调控网络。

In mammals, the gonad is composed of germ cells and somatic cells. The gonads have the potential of bidirectional differentiation before sex determination. The differentiation of somatic cells in the gonad determines the development of testis or ovary, and this process is regulated by many factors. SRY, SOX9, SOX3, SOX8, SOX10, FGF9/FGFR2, PGD2, AMH, and DMRT1 are involved in the differentiation of testis. By contrast, FOXL2, CTNNB1, RSPO1, WNT4, Follistatin, ERα/β, and BMP2 play important roles in ovary development. If these molecular regulatory networks are damaged by endogenous or exogenous factors, disorders of sex differentiation, even sex reversal, will occur. In this review, the regulation of somatic cell fate during gonad primordium formation and sex determination in mouse model was discussed.

Key words: sex differentiation; sex determination; germ cells; somatic cells
