    Characterization of bovine bone marrow derived mesenchymal stem cells and immunostaining of differentiated neurospheres
    (Hellenic Veterinary Medical Society, 2023) Dikmen, Tayfun; Özden Akkaya, Özlem; Nawaz, Shah; Erdoğan, Metin
    Stem cell differentiation has been a key element for the therapeutical applications for various disorders. The novel anti-inflammatory and angiogenic findings and potential applications for both autologous and allogenic studies have emphasized about the usage of mesenchymal stem cells in the clinical trials. The neurosphere differentia-tion studies and their role for peripheral nerve injuries have gained momentum recently. Following study emphasized on the isolation of stem cells from bovine bone marrow and characterization of their mesenchymal potential by PCR followed by their differentiation into mesodermal lineages and into neurospheres under specific induction media. The generated neurospheres were further investigated for their potential expressions of neuroprogenitor markers Sox2, Nestin and neurofilament protein β-III Tubulin by immunofluorescence staining. The results of following study high-light the unique potential of bone marrow derived mesenchymal stem cells for translational research and regenerative therapy in nervous tissue injuries.

    Characterizing the amniotic fluid-derived stem cells and optimizing the passage number for targeted applications
    (Faculty Of Veterinary Science, University Of Agriculture, 2024) Dikmen, Tayfun; Erdoǧan, Metin; Altunbaş, Korhan
    Mesenchymal stem cells are considered potent sources that can be used for tissue regeneration and treatment of various diseases and syndromes. Among the mesenchymal stem cells, amniotic fluid-derived stem cells come forward as they possess some pluripotent properties and there are no serious ethical concerns upon their derivation. Therefore, gaining a better understanding of the nature of amniotic fluid stem cells is important. Although it is known that stem cells show slightly different characteristics between passages, scientists often consider only cell numbers and the proliferation pattern of the cells when deciding the passage to use in their studies. In this study, it was aimed to characterize rat amniotic fluid-derived stem cells for their mesenchymal and pluripotent features and make inter-passage comparisons by real-time qPCR to reveal their distinctions between different passages, and eventually help decide the appropriate passage numbers to be used in future research. The outcomes of the study showed that using rat amniotic fluid-derived stem cells at P5 could be beneficial for mesodermal differentiation studies and using them in earlier passages may be more favorable for the studies requiring better ectodermal differentiation properties.
