Comparison of mesenchymal stem cells isolated from various tissues of isogenic mini-pig

Abstract

The present study compared the cellular properties based on cell surface differentiation markers, telomerase activity, stem cell-specific transcripts and differentiation capacity into adipocytes, osteocytes and neurocytes in multipotent mesenchymal stem cells (MSCs) isolated from bone marrow (BMSCs), adipose (ASCs), ovarian (OSCs), muscle (MuSCs) and skin (SSCs) tissues of the same donor mini-pig. Using flow cytometry, all isolated MSCs expressed stem cell-positive surface markers CD29, CD44 and Vimentin, at a high level. Using reverse transcription-polymerase chain reaction, BMSCs, ASCs and SSCs showed higher expression of stem cell-specific transcripts (NANOG, OCT-4 and SOX-2) as compared to OSCs and MuSCs. Telomerase activity was detected by relative-quantitative telomerase repeats amplification protocol at a similar level in all MSCs. Further, analysis of cytochemical staining and lineage-specific transcripts demonstrated that all MSCs get easily differentiated into adipocytes, except for OSCs, whereas, BMSCs and MuSCs easily differentiated into osteocytes, compared to ASCs, OSCs and SSCs. Furthermore, all MSC groups showed the same level of capacity for neurocytes differentiation. Based on these results, the cellular properties were dominantly expressed in BMSCs, ASCs and SSCs, whereas the differentiation capacity was dominantly expressed in BMSCs and MuSCs, compared to others MSCs. Taken together, BMSCs could potentially be used as a good source of MSCs for clinical application and fundamental stem cell research.

Honey‐incorporated nanofibre reduces replicative senescence of umbilical cord‐derived mesenchymal stem cells

“…Researchers have identified four markers, CD29, CD44, CD105 and vimentin, strongly expressed in undifferentiated mesenchymal stem cells [36, 37]. In the present study, the expression of vimentin (green) (Fig.…”

Biomedical cell product model for preclinical studies carried out on a large laboratory animal

“…Выбранные подходы позволили провести характеристику клеток, полученных из жировой ткани свиньи, по основным параметрам, необходимым для их идентификации и использования в экспериментальной работе: жизнеспособность, морфология, диференцировочный потенциал, иммунофенотип. Полученные нами данные по выделению и характеристике MSCs из жировой ткани свиньи, как и приведенные в литературе [16,17], демонстрируют способность pASCs к остеогенной, адипогенной и хондрогенной дифференцировке, проявлению типичных морфологических характеристик и определенного иммунофенотипа.…”
