乌鸡是我国特有的鸡种,具有很好的补血功能,利用乌鸡开发新的补血产品具有很大优势。该研究通过对贫血小鼠灌喂添加营养素(EDTAFeNa和维生素)的乌鸡肽配方样品,测试对其造血能力的恢复功效并通过探究信号通路研究造血作用机制。实验通过使用环磷酰胺和乙酰苯肼制造小鼠贫血模型,并检测外周血象、骨髓病理学观察、间接胆红素含量、ATP酶活力、造血因子水平以及JAK2/STAT3信号通路。结果表明乌鸡肽营养素配方可以显著恢复外周血细胞和骨髓造血干细胞数量;减少间接胆红素含量,提高ATP酶活力从而保护红细胞免受破裂损伤;通过分泌促红细胞生成素(erythropoietin,EPO)、重组巨噬细胞粒细胞集落刺激因子(human granulocyte-macrophage colony stimulating factor, GM-CSF)和白细胞介素-3(interleukin-3, IL-3)造血因子促进造血细胞恢复,并通过JAK2/STAT3信号通路调控造血细胞增殖分化。该研究为乌鸡肽的开发和利用提供了指导。

As a unique species of chicken in China, the black-bone silky fowl has excellent haemopoietic properties. The black-bone silky fowl has been utilized to great advantage in the development of new blood supplement products. This study aimed to produce a sample of black-bone silky fowl peptide formula supplemented with the nutrients (EDTAFeNa, vitamins B1, B6, B12, and folic acid). The efficacy of the sample in restoring haematopoiesis was tested by feeding them to mice and the mechanism of haematopoiesis was investigated. The anemia model of mice was made by using cyclophosphamide and acetylphenylhydrazine, and the peripheral blood picture, bone marrow pathological observation, indirect bilirubin content, ATPase activity, hematopoietic factor level, and JAK2/STAT3 signaling pathway were detected. Results showed that black-bone silky fowl peptide nutrient formula could significantly restore peripheral blood cell and bone marrow haematopoietic stem cell populations. It reduced indirect bilirubin levels and increased ATPase activity, thus protecting red blood cells from rupture damage. It promoted hematopoietic cell recovery through the secretion of erythropoietin (EPO), human granulocyte-macrophage colony-stimulating factor (GM-CSF), and interleukin-3 (IL-3) hematopoietic factors, and regulated hematopoietic cell proliferation and differentiation through the JAK2/STAT3 signaling pathway. The study provided guidance for the development and utilization of black-bone silky fowl peptide.
