Not only regulated by cytokines,hematopoietic cells proliferation and differentiation is also closely associated with cell cycleregulators. Proliferation cell nuclear antigen is an important cell cycle regulatory proteinand the key factor driving cells into S-phase from G_1-phase, and also plays an important role inregulating haematopoiesis.

增殖细胞核抗原(proliferationg cell nuclear antigen，PCNA)是重要的细胞周期调控蛋白，是促进细胞从G_1期进入S期的关键因素，其在造血细胞增殖发育过程中也发挥重要作用。

In order to confirm this suspect, we choosed a cultured rat granulation tissue fibroblasts model in vitro and applied RT-PCR and cell-ELISA technology to detect the changes of firbroblasts intrinsic EGF, bFGF, TGFβ-1 with their receptors gene expressions and protein synthesises after stimulated by SP. Our purpose was to explore the possible effects and patterns imposed by SP on fibroblasts intrinsic growth factors and their receptors expressions, which maybe offer theoretical basis for promoting wound healing via improving nervous functions and regulating neuropeptides secretions.

为进一步验证这一推测，同时排除在体多因素干扰，我们采用了一种大鼠肉芽组织成纤维细胞体外培养模型，采用RT-PCR与细胞ELISA技术，检测SP刺激成纤维细胞后，成纤维细胞内源性EGF、bFGF、TGFβ-1及其受体基因表达和蛋白合成的改变情况，探讨SP对成纤维细胞内源性生长因子及其受体表达的影响以及方式，以期为经由改善神经功能、调节神经肽分泌途径促进伤口愈合提供理论依据。
