This study reports the generation of a new human muscle tissue equivalent from skeletal muscle-derived stem cells and human umbilical vein endothelial cells (HUVECs). Skeletal muscle stem cells were isolated by the preplate technique and differentiated into neuron-like cells that were positive for neuronal beta-tubulin3 and nestin and negative for the astrocyte marker glial fibrillary acidic protein (GFAP). Coculture of skeletal muscle stem cells with the HUVECs under optimized fetal bovine serum and media conditions resulted in formation of a capillary network among the multinucleated myotubes. The neuron-like cells derived from the human skeletal muscle stem cells were seeded onto vascularized myotubes to obtain the neuromuscular junctions in the coculture. At the end of 24 h of coculture, the neuron-like cells were found to be in association with the myotubes. This model represents a novel complex in vitro human skeletal muscle model containing advanced capillary networks and interacting myotubes and neurons, and it can be used for in vitro drug testing or for skeletal muscle regeneration either through application of cellular therapy or cell-laden tissue-engineered muscle constructs.


The effect of diabetes on rat skeletal muscle tissues at molecular level
Bozkurt, Özlem; Severcan, Feride; Department of Biology (2006)
In the present study Fourier Transform Infrared Spectroscopy was used to examine the effects of streptozotocin-induced diabetes mellitus on the structural components of slow- and fast-twitch rat skeletal muscles, at molecular level. Diabetes mellitus is a chronic disorder of carbohydrate, fat and protein metabolism, which is characterized by hyperglycemia caused by a defective or deficient insulin secretory response. The effect of diabetes is seen on a variety of tissues leading to important secondary compl...
In vitro evaluation of PLLA/PBS sponges as a promising biodegradable scaffold for neural tissue engineering

In tissue engineering, the use of poly-L-lactic acid (PLLA)/polybutylene succinate (PBS) blend for the construction of scaffold is very limited. Moreover, polymeric sponges fabricated from PLLA/PBS have not been studied for neural tissue engineering. In the present study, the potential of the utility of PLLA/PBS polymeric sponges seeded with Schwann cells was investigated. PLLA and PBS were blended in order to increase the processability and tune the crystallinity, porosity, and degradation rate of the resu...

In the last decade, hydroxycinnamic acids (HCA) have gained increasing attention from researchers due to their antioxidant potential. The aim of this study was to examine in detail the impact of dietary HCA on particular types of P450 and also selected phase II and antioxidant enzymes in Wistar rat. HCA (10 mu M/kg/day, i.p.) was administered for ten continuous days. Examination of the activities and mRNA and protein levels revealed that CYP2B, 2C6 and 3A enzyme activities were not altered significantly, wi...
Characterization and identification of human mesenchymal stem cells at molecular level
Aksoy, Ceren; Severcan, Feride; Çetinkaya, Duygu Uçkan; Department of Biotechnology (2012)
Bone marrow mesenchymal stem cells (BM-MSCs) are pluripotent cells that can differentiate into a variety of non-hematopoietic tissues. They also maintain healthy heamatopoiesis by providing supportive cellular microenvironment into BM. In this thesis, MSCs were characterized in terms of their morphological, immunophenotypical and differentiation properties. Then, they were examined by attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy together with hierarchical clustering, and FT...
Influence of STRO-1 selection on osteogenic potential of human tooth germ derived mesenchymal stem cells
Ercal, Pinar; Pekozer, Gorke G.; Gumru, Osman Z.; KÖSE, GAMZE; Ramazanoglu, Mustafa (Elsevier BV, 2017-10-01)
Mesenchymal stem cells derived from the human tooth germ (hTGSCs) are a heterogeneous cell population that can differentiate into osteogenic, neurogenic, and adipogenic lineages. The aim of this study was to compare the osteogenic differentiation capacity of STRO-1 positive (STRO-1 +) hTGSCs and unsorted heterogeneous hTGSCs and to establish if STRO-1 + cells are more committed to osteogenic differentiation. HTGSCs were isolated from impacted third molar tooth germ tissues of adolescents, and a subpopulatio...
