Background

The mesenchymal stem cells (MSCs) are multipotent progenitors cells that can differentiate into a variety of cell types, including bone cells, cartilage cells, and fat cells [1]. Adipogenesis, the differentiation of mesenchymal stem cells into adipocytes, entails activating transcription factors and signaling pathways. It comprises a two-step process: stem cell determination and preadipocyte differentiation [2,3,4]. Briefly, at the beginning of adipogenesis is the signaling of bone morphogenetic proteins (BMPs), which belong to the transforming growth factor β (TGF-β) superfamily, a family of proteins that play a role in the conversion of pluripotent stem cells into the adipocyte lineage [5]. Then it is often portrayed as a cascade of regulatory events, the first wave involving CCAAT/enhancer-binding protein β (C/EBPβ) and C/EBPδ and sterol-regulatory element binding protein 1 (SREBP1), and these transcription factors being involved in the activation of the second wave, which includes C/EBPα and PPARγ, which coordinately activate the transcription of genes that give rise to the adipocyte phenotype [4].

Pigs, due to their physiological similarities to humans, serve as valuable cellular models for advancing stem cell therapies, regenerative medicine, and transplantation [6, 7]. Porcine MSCs are utilized as large animal models in regenerative medicine, preclinical studies, and transplantation for both human and veterinary applications, benefiting the livestock industry [7,8,9]. Comprehensive understanding of molecular changes during MSC transition from self-renewal to differentiation, particularly in pig adipogenesis, and related technologies, contributes to diverse experimental research.

Various source of tissue for derived MSCs influence functional properties of the cells was reported [10,5.
