Some tissues retain extensive regeneration potential through out adult life and remain as active sites of cell production. Various cell types present in tissues are being produced through proliferation and progressive specialization from a pool of stem cells. In this regard, adult stem cells (ASCs) are multipotent progenitor cells with an ability to proliferate in vitro and undergo extensive self-renewal and differentiation into a wide range of cell types, including adipocytes, chondrocytes, osteocytes, myocytes, cardiomyocytes and neurons. In addition, recent studies showing the abilities of ASCs in generating oocytes-like cells (OLCs) present new perspectives to understand the specification and interaction during the germ cell formation and oogenesis. In the present study, ASCs were established from skin, adipose and ovarian tissues of minipigs. Isolated cells exhibited a fibroblast-like morphology with higher proliferation potential and stronger alkaline phosphatase (AP) activity. ASCs from all tissues expressed pluripotent transcriptional factors, such as Oct-3/4, Nanog and Sox-2 and phenotypic markers, including CD29, CD44, CD90 and vimentin. Further, ASCs were successfully dIfferentiated into osteocytes, adipocytes and neuron-like cells. Upon induction in oogenesis specific media, all ASCs were capable of differentiation into OLCs by exhibiting distinct morphological features. Generated OLCs expressed a range of germ cell specific markers, such as Vasa, deleted in Azoospermia-like (DAZL) factor, stella, c-kit, c-Mos, synaptonemal complex protein 3 (SCP-3), growth differentiation factor 9b (GDF- 9b), zona pellucida C (ZPC) and follicle stimulating hormone receptor (FSHR) at different time points of induction. Differentiated OLCs were also positive for the expression of Vasa and DAZL protein markers. Our findings showing that OLCs can be generated from ASCs of different tissue origin may offer pig as a suitable model for designing transgenic application strategies for reproductive tissue therapy. However, further studies are needed to understand the cellular and molecular mechanisms involved in germ cell differentiation from tissue specific stem cells.
