To date, numerous soluble substances have been demonstrated to be present at different concentrations with or without endometriosis. We revealed that Stem cell factor (SCF) concentration in PF is increased in women with enodmetriosis. The concentrations of SCF in PF tended to decrease with the progression of endometriosis. SCF is known to stimulate mast cell functions. In view of human endometrium having SCF receptors, it can be speculated that SCF in PF may affect fertility of women with early stages of endometriosis by modulating functions of mast cells and/or endometrial cells. We also detected the increase of sTNFRI and sTNFRII concentrations in PF of women with endometriosis. The increase may stimulate the development of endometriosis, as these soluble molecules may antagonize TNFα mediated apoptosis of endometriotic cells. We further demonstrated that IP-10 concentrations in PF were significantly lower in women with advanced stages of endometriosis as compared to those with early stages. Decreased concentrations of IP-10 in PF from women with advanced stages of endometriosis may imply that the peritoneal environment of these women is permissive to the development of the disease by enhancing angiogenesis and/or modulating inflammatory/ immunological responses.

到目前为止，许多可溶性物质已被证明存在于不同浓度的子宫内膜异位症或非子宫内膜异位症中。我们发现子宫内膜异位症患者PF中干细胞因子(SCF)浓度升高。随着子宫内膜异位症的进展，PF中SCF的浓度呈下降趋势。已知干细胞因子可刺激肥大细胞功能。鉴于人子宫内膜存在SCF受体，推测PF中的SCF可能通过调节肥大细胞和/或子宫内膜细胞的功能而影响早期子宫内膜异位症患者的生育能力。我们还检测了子宫内膜异位症患者外周血中sTNFRI和sTNFRII的浓度升高。这些可溶性分子可能拮抗肿瘤坏死因子α介导的子宫内膜异位症细胞凋亡，从而促进子宫内膜异位症的发生。我们进一步证明，与早期子宫内膜异位症患者相比，晚期子宫内膜异位症患者PF中IP-10浓度显著降低。晚期子宫内膜异位症患者外周血中IP-10浓度的降低可能意味着这些女性的腹膜环境通过促进血管生成和/或调节炎症/免疫反应而允许疾病的发生。
