The adnexa fetal tissues are sources of mesenchymal stromal cells (MSCs) due to their noninvasive harvest, with all biological material discarded most of the time. MSCs are a promise regarding to their plasticity, self-renewal, differentiation potentials, immunomodulatory and anti-inflammatory properties, which have made clinical stem cell therapy a reality. The present study aimed to characterize and evaluate the immunomodulation ability of bovine mesenchymal cells collected from bovine amniotic fluid (bAFMSCs) isolated and subjected to sixth consecutive culture passages . The multilineage properties of the bAFMSCs collections confirmed the ability to undergo adipogenic, chondrogenic and osteogenic differentiation. The mesenchymal gene transcription were detected in bAFMSCs, whereas and were not detected. Regarding cytokine mRNA expression, and were downregulated, while was highly regulated in all studied passages. The present study demonstrated the immunological properties and multipotency of bAFMSCs collections, and thus, they can be tested in cattle pathological treatments or multiplication by nuclear transfer cloning.
胎儿附属组织是间充质基质细胞(MSCs)的来源,因为它们可以无创获取,且大部分生物材料在大多数情况下都会被丢弃。MSCs因其可塑性、自我更新能力、分化潜能、免疫调节和抗炎特性而颇具前景,这些特性已使临床干细胞治疗成为现实。本研究旨在对从牛羊水分离并连续传代培养至第六代的牛间充质细胞(bAFMSCs)的免疫调节能力进行表征和评估。bAFMSCs群体的多谱系特性证实了其具有向脂肪细胞、软骨细胞和成骨细胞分化的能力。在bAFMSCs中检测到了间充质基因转录,而未检测到[此处原文缺失具体基因名称]和[此处原文缺失具体基因名称]。关于细胞因子mRNA表达,[此处原文缺失具体基因名称]和[此处原文缺失具体基因名称]表达下调,而[此处原文缺失具体基因名称]在所有研究传代中均高度表达。本研究证明了bAFMSCs群体的免疫特性和多能性,因此,它们可用于牛的病理治疗测试或通过核移植克隆进行增殖。
