摘要: 本研究旨在探讨不同浓度的神经肽P物质(SP)刺激对内蒙古白绒山羊皮肤干细胞BMP2、BMP4基因表达的影响。本研究分别采用0(对照组)、1×10-6、1×10-7、1×10-8、1×10-9 mol/L 5个浓度梯度的SP对内蒙古白绒山羊皮肤干细胞进行刺激处理,并分别于第0、7、14及21天采用实时荧光定量PCR方法鉴定BMP2和BMP4基因的表达量。结果显示,1×10-6和1×10-8 mol/L的SP促进BMP2、BMP4的表达;在7和14 d时,SP 1×10-8 mol/L组BMP2的表达量显著高于SP 1×10-6 mol/L组(P<0.05),SP 1×10-6 mol/L组BMP4的表达量与SP 1×10-8 mol/L组差异不显著(P>0.05);在21 d时,SP 1×10-8 mol/L、SP 1×10-6 mol/L组BMP2、BMP4的表达量都明显降低,其中SP 1×10-8 mol/L组BMP2的表达量显著高于1×10-6 mol/L组(P<0.05),SP 1×10-6 mol/L组BMP4的表达量与SP 1×10-8 mol/L组差异不显著(P>0.05)。结果表明,SP 1×10-6和1×10-8 mol/L不仅对内蒙古白绒山羊皮肤干细胞BMP2、BMP4基因的表达量有影响,而且为皮肤干细胞的定向分化提供理论基础。

Abstract: This study was aimed to explore the expression of BMP2 and BMP4 genes in skin stem cells of Mongolia Cashmere goat with the influence of different concentrations of neuropeptide P (SP).We set five different SP concentrations (0, 1×10-6, 1×10-7, 1×10-8 and 1×10-9 mol/L) to stimulate the skin stem cells, then identified the expression quantities of BMP2 and BMP4 at days of 0, 7, 14 and 21 by Real-time quantitative PCR with the purpose of determining the optimum SP concentration for the differentiation of skin stem cells.The results showed that SP with the concentrations of 1×10-6 and 1 ×10-8 mol/L promoted the expression of BMP2 and BMP4;The expression of BMP2 at 7 and 14 d in SP 1×10-8 mol/L group was significantly higher than that of the SP 1×10-6 mol/L group (P<0.05);The expression of BMP4 in SP 1×10-6 mol/L group had no significant difference with the SP 1×10-8 mol/L group (P>0.05);At 21 d, the expression of BMP2 and BMP4 significantly decreased in SP 1×10-8 and the SP 1×10-6 mol/L groups, and the expression of BMP2 in the SP 1×10-8 mol/L group was significantly higher than that of the 1×10-6 mol/L group (P<0.05), while the expression of BMP4 in the SP 1×10-6 mol/L group had no significant difference with that of SP 1×10-8 mol/L group (P>0.05).The results indicated that the concentrations of 1×10-6 and 1×10-8 mol/L not only might affect the expression of BMP2 and BMP4 of skin stem cells, but also provided a theoretical basis for the directional differentiation of skin stem cells.
