Mesenchymal stem cells (MSCs) are promising candidates for tissue regeneration, cell therapy, and cultured meat research owing to their ability to differentiate into various lineages including adipocytes, chondrocytes, and osteocytes. As MSCs display different characteristics depending on the tissue of origin, the appropriate cells need to be selected according to the purpose of the research. However, little is known of the unique properties of MSCs in pigs. In this study, we compared two types of porcine mesenchymal stem cells (MSCs) isolated from the dorsal subcutaneous adipose tissue (adipose-derived stem cells (ADSCs)) and Wharton's jelly of the umbilical cord (Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs)) of 1-day-old piglets. The ADSCs displayed a higher proliferation rate and more efficient differentiation potential into adipogenic and chondrogenic lineages than that of WJ-MSCs; conversely, WJ-MSCs showed superior differentiation capacity towards osteogenic lineages. In early passages, ADSCs displayed higher proliferation rates and mitochondrial energy metabolism (measured based on the oxygen consumption rate) compared with that of WJ-MSCs, although these distinctions diminished in late passages. This study broadens our understanding of porcine MSCs and provides insights into their potential applications in animal clinics and cultured meat science.
间充质干细胞(MSCs)因其能够分化为包括脂肪细胞、软骨细胞和骨细胞在内的各种谱系,在组织再生、细胞治疗和培养肉研究方面具有广阔的应用前景。由于MSCs根据其来源组织表现出不同的特性,因此需要根据研究目的选择合适的细胞。然而,对于猪MSCs的独特特性知之甚少。在本研究中,我们比较了从1日龄仔猪的背部皮下脂肪组织(脂肪来源干细胞(ADSCs))和脐带华通氏胶(华通氏胶来源间充质干细胞(WJ-MSCs))中分离出的两种猪间充质干细胞。与WJ-MSCs相比,ADSCs表现出更高的增殖率以及向脂肪生成和软骨生成谱系的更高效分化潜力;相反,WJ-MSCs在向成骨谱系的分化能力方面表现更优。在早期传代中,与WJ-MSCs相比,ADSCs表现出更高的增殖率和线粒体能量代谢(基于耗氧率测量),尽管这些差异在后期传代中逐渐减小。本研究拓宽了我们对猪MSCs的理解,并为其在动物临床和培养肉科学中的潜在应用提供了见解。
