“…In addition, cTnI level was significantly higher in 5-aza-treated groups compared to control group. Our results are in line with studies showing successful differentiation of MSCs into cardiomyocytes by 5-aza treatment (11,14,(36)(37)(38). These studies have confirmed the increased expression of cardiac specific genes such as cardiac troponins, GATA4, myosin heavy chain in 5-azatreated MSCs.…”

“…Synthetic agents are preferred because they are more stable than protein-based growth agents, have a longer half-life, and do not require living organisms for synthesis. 5-aza has been shown to induce the differentiation of stem cells into a variety of cells, including cardiomyocytes (11,14,36). Although the mechanism by which 5-aza promotes cardiomyogenic differentiation remains unclear, it has been shown that it effectively induced the up-regulation of cardiomyogenic specific genes such as cTnT, cTnI, α-cardiac actin and Nkx2 through the ERK pathway (13,22).…”

Amaç: Mezenkimal kök hücreler, çeşitli protokoller kullanılarak in vitro koşullarda kolaylıkla kardiyomiyositlere farklılaşabilir. Ancak bu protokollerde kullanılan ajanların hücre canlılığı üzerinde bazı olumsuz etkileri olduğu bildirilmiştir. Azasitidin mezenkimal kök hücreleri kalp kası hücrelerine farklandırmak için kullanılmaktadır. Bu çalışmanın amacı, bir GLP-1 reseptör agonisti olan Eksenatid'in insan yağ dokusu kaynaklı kök hücrelerinin kardiyomiyositlere farklılaşması ve canlılığı üzerindeki etkilerini araştırmaktır. Gereç ve Yöntem: Azasitidin ve Eksenatid'in insan yağ doku kaynaklı mezenkimal kök hücreler üzerinde hücre canlılığı ve proliferasyonu üzerindeki etkileri ile sitotoksisite testleri yapıldı. Farklılanma protokolü için, hücreler dört hafta boyunca Azasitidin ve Eksenatid ile inkübe edildi. Hücrelerin morfolojik değişiklikleri izlendi ve kardiyomiyojenik farklılaşma belirteçlerinin (cTnI, GATA4 ve MYH7) ekspresyonları immünohistokimyasal olarak değerlendirildi. Ayrıca kültürlerdeki kardiyak troponin I (cTnI) seviyeleri enzime bağlı immünosorbent testi kullanılarak ölçüldü. Veriler, tek yönlü varyans analizi (ANOVA) ve post-hoc testi ile değerlendirildi. Bulgular: İnsan yağ doku kaynaklı mezenkimal kök hücreler üzerine Azasitidin uygulaması, kontrole grubuna kıyasla hücre canlılığını önemli ölçüde azaltırken (%54.4) hücrelerin Azasitidin+Eksenatid ile uygulaması doza bağlı bir şekilde hücre ölümünü önledi. Azasitidin ve Eksenatid uygulanan hücreler, kardiyomiyojenik farklılaşma ile uyumlu önemli morfolojik değişiklikler ve kardiyomiyojenik belirteçlerde artış gösterdi. Ayrı ayrı ve birlikte uygulama yapılan gruplarda cTnI seviyeleri kontrole göre anlamlı derecede yüksek bulundu. Sonuç: Bu bulgular GLP-1 reseptör agonisti Eksenatid'in, Azasitidin uygulamasının neden olduğu hücre hasarını azaltarak İnsan yağ doku kaynaklı mezenkimal kök hücrelerin kardiyomiyojenik farklılaşması üzerinde faydalı etkileri olabileceğini düşündürmektedir.

“…So far, several kinds of stem cells, including embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs) and mesenchymal stem cells (MSCs) are proven to be pluripotent, giving rise to all the cells from the three embryonic germ layers [13,14]. Evidence has accumulated that both murine and human adult tissues contain early-development stem cells with a broader differentiation potential than other adult monopotent stem cells [15,16]. The nonhematopoietic stem cells appear to be heterogeneous and contain cells committed to mesenchymal and endothelial lineages, as well as more primitive multipotential cells resembling progenitors of germ cells [17].…”

BACKGROUND: Studies have shown that histone H3 methylation is involved in regulating the differentiation of Bone Marrow Mesenchymal Stem Cells (BMSCs). KDM5B can specifically reduce the level of histone 3 lysine 4 trimethylation (H3K4me3), thereby activating the expression of related genes and participating in biological processes such as cell differentiation, embryonic development and tumor formation. Whether KDM5B is involved in the regulation of BMSCs differentiation into cardiomyocytes through the above manner has not been reported.OBJECTIVE: To investigate the effect of KDM5B on the induction and differentiation of swine BMSCs into myocardial cells in vitro.METHODS: Swine bone marrow BMSCs were isolated and cultured, and the overexpression, interference expression and blank vector of KMD5B were constructed and transfected by lentivirus. BMSCs was induced to differentiate into cardiomyocytes by 5-azacytidine (5-AZA) in vitro, and the differentiation efficiency was compared by immunofluorescence, RT-PCR, Western Blot and whole-cell patch clamp detection.RESULT: Compared with the control group, the expression levels of histone H3K4me3 and pluripotency gene Nanog in KDM5B overexpression group were significantly decreased, while the expression level of key myocardial gene HCN4 and myocardial marker gene α-Actin and cTNT were significantly increased, and the Na+ current density on the surface of differentiated myocardial cell membrane was significantly increased. Meanwhile, the corresponding results of the KDM5B silent expression group were just opposite. CONCLUSIONS: It indicated that enhanced KDM5B expression could promote the differentiation of BMSCs into cardiomyocytes and improve the differentiation efficiency by controlling H3K4 methylation levels.
