Recent clinical developments in tissue bioengineering have applications in acute cardiac ischemia and infarction and include the use of stem cells that combine injectable scaffold material. This study aimed to evaluate the effects of adipose-derived stem cells (ADSCs) that combine the Matrigel scaffold on cardiac morphology/functions. The autologous ADSCs myocardial infarction (MI) model was induced by the permanent ligation method of the left anterior descending coronary artery (LAD). MI-operated rats were randomly divided into PBS group, Matrigel group, PBS plus ADSCs group (PBS+ADSCs), and Matrigel plus ADSCs group (Matrigel+ADSCs). Matrigel was used as an injectable scaffold. Rats with a 1-week-old …

Understanding of the functions of microRNAs in breast cancer and breast cancer stem cells have been a hope for the development of new molecular targeted therapies. Here, it is aimed to investigate the differences in the expression levels of let-7a, miR-10b, miR-21, miR-125b, miR-145, miR-155, miR-200c, miR-221, miR-222 and miR-335, which associated with gene and proteins in MCF-7 (parental) and MCF-7s (Mammosphere/stem cell-enriched population/CD44+/CD24-cells) cells treated with paclitaxel. MCF-7s were obtained from parental MCF-7 cells. Cytotoxic activity of paclitaxel was determined by ATP assay. Total RNA isolation and cDNA conversion were performed from the samples. Changes in expression levels of …

Turkish Journal of Biology
Oxidative stress is the primary cause of lowering of the body's immune status. It arises as a result of intense metabolic processes in humans and animals that involve a decrease in antioxidant enzymes activity at the expense of increased production of free radicals and reactive oxygen species (ROS). Consequently, this leads to oxidation of lipids, proteins, DNA, and RNA, causing cell proliferation reduction, faster cell aging, and subsequent degradation. Currently, there is a search for methods to maintain an oxidation-antioxidant balance. The results of many authors' research point to the effectiveness of the use of mesenchymal stem cells (MSCs) in …
Pluronic Pf68 Increases Transfection Efficiency In Electroporationof Mesenchymal Stem Cells, Safa Aydin, Mehmet Emi̇r Yalvaç, Ferruh Özcan, Fi̇kretti̇n Şahi̇n
Pluronic Pf68 Increases Transfection Efficiency In Electroporationof Mesenchymal Stem Cells, Safa Aydin, Mehmet Emi̇r Yalvaç, Ferruh Özcan, Fi̇kretti̇n Şahi̇n
Turkish Journal of Biology
Electroporation is a safe and efficient method to transfect human tooth germ stem cells (hTGSCs), which are mainly mesenchymal stem cells (MSCs). In this study, pluronic F68 (PF68), a nonionic and low-foaming surfactant, was used for the first time to increase the transfection efficiency in electroporation of hTGSCs. Our results revealed that when PF68 was used in the preincubation, electroporation, and recovery medium, it dramatically increased transfection efficiency. Moreover, use of PF68 did not alter the differentiation capacity of hTGSCs, whereas cells electroporated without PF68 had significantly lower expression of Oct-4, pluripotency marker gene, and alkaline phosphatase (ALP) activity upon …

Cardiomyogenic differentiation from mesenchymal stem cells has emerged as a novel approach for repair of damaged myocardium. Cell transplantation through direct cell injection is not an optimal method due to the lack of cell-extracellular matrix interactions. In the present study, differentiation potential of human adipose-derived stem cells (ASCs) to cardiomyocytes has been investigated by growing them on hyaluronic acid/gelatin (HA/G) plasma gels and coverslips and supplementing the growth medium with chemical modifiers (activin-a, BMP-4, insulin, valproic acid, and 5-azacytidine) in various combinations. The HA/G plasma gels were produced from human blood plasma-derived fibrinogen, gelatin, and human umbilical cord-derived hyaluronic acid. …

Myelin disorders burden millions of people around the world, yet existing therapies are inadequate to cure them. Current remedies commonly treat the symptoms with minimal to no effect on the actual cause of the disorder. The basis and/or the mechanism of demyelination is not known for many of the disorders either. In recent years, stem cells of variable origin have been used in clinical trials as transplant agents to restore the defective biochemical process or the damaged tissue. We summarize the outcomes of these trials for demyelination disorders. The capability of reprograming mature cells into stem cells equips researchers with …

Over recent years stem cells have stood out as a promising tool for regenerative medicine, providing alternative therapeutic solutions for a large number of diseases. Many clinical trials using stem cells or induced pluripotent stem cells are focused on the repair and regeneration of various tissues and organs in degenerative diseases, whose current treatment only succeeds in slowing down the progression of the disease. Although the preliminary results are interesting, further studies are required in order to evaluate the safety and benefits of stem cell therapy, considering the teratoma development and ethical considerations in embryonic stem cell cases or reprogramming-induced …

Current procedures used for skin injury reepithelization have yet to improve. At present, stem cell-based therapies provide great potential in repairing different damaged tissues due to the multipotent character of these cells. This study aimed to investigate the in vitro differentiation capacity of human adipose-derived stem cells (ASCs) into epidermal cells and to evaluate their interaction with HaCaT keratinocytes in coculture experimental models that mimicked the living environment of human skin. The mesenchymal phenotype of isolated stem cells was indicated by their spindle-shaped morphology and the expression of specific surface markers CD73, CD90, and CD105. After 21 days of cultivation …

Mechanisms Of Pluripotency And Epigenetic Reprogramming In Primordial Germ Cells: Lessons For The Conversion Of Other Cell Types Into The Stem Cell Lineage, Suresh Palamadai Krishnan
Turkish Journal of Biology
Primordial germ cells (PGCs) provide an excellent tool to better understand ancestor?descendent relationships as well as the efficiency and molecular mechanisms governing pluripotency in the reprogramming of somatic cells, since the latter type of cells have a relatively lower efficiency of conversion to pluripotent cells. This kind of comparison has gained credence from the commonalities regarding the expression of key transcription factors such as octamer-binding transcriptionhttp://en.wikipedia.org/wiki/Transcription_factor factor-4 (Oct3/4), SRY-related HMG box (Sox2), myelocytomatosis (c-Myc), and Nanog, as well as redundancy in terms of Kruppel-like factor 2 (Klf2), Kruppel-like factor 5 (Klf5), estrogen-related receptor beta (Esrrb), and estrogen-related receptor gamma (Esrrg) …
