Co-culture of bone forming cells and endothelial cells to induce pre-vascularization is one of the strategies used to solve the insufficient vascularization problem in bone tissue engineering attempts. In the study, primary cells isolated from 2 different tissues of the same animal, rat bone marrow stem cells (RBMSCs) and rat aortic endothelial cells (RAECs) were co-cultured to study the effects of co-culturing on both osteogenesis and angiogenesis. The formation of tube like structure in 2D culture was observed for the first time in the literature by the co-culture of primary cells from the same animal and also osteogenesis and angiogenesis were investigated at the same time by using this co-culture system. Co-cultured cells mineralized and formed microvasculature beginning from 14 days of incubation. After 28 days of incubation in the osteogenic medium, expression of osteogenic genes in co-cultures was significantly upregulated compared to RBMSCs cultured alone. These results suggest that the co-culture of endothelial cells with mesenchymal stem cells induces both osteogenesis and angiogenesis.

Mesenchymal stem cells (MSCs) are promising cell sources for tissue engineering applications as they can differentiate into a variety of adult cells types including osteoblasts. In vivo microenvironment of stem cells is known to provide both biochemical signals and micro- and nanoscale physical cues that influence the behavior and fate of stem cells. The use of soluble chemical factors is the most common strategy to guide the commitment of MSCs to specific lineages, but it is a cause of concern such as unsa...

The effects of double release of insulin-like growth factor I (IGF-I) and growth factor 1 (TGF1) from nanoparticles on the growth of bone marrow mesenchymal stem cells and their differentiation into cartilage cells were studied on PLGA scaffolds. The release was achieved by using nanoparticles of poly(lactic acid-co-glycolic acid) (PLGA) and poly(N-isopropylacrylamide) (PNIPAM) carrying IGF-I and TGF1, respectively. On tissue culture polystyrene (TCPS), TGF-1 released from PNIPAM nanoparticles was found to ...
Characterization and identification of human mesenchymal stem cells at molecular level

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 microenvironment on tissue engineering applications
Sayın, Esen; Hasırcı, Vasıf Nejat; Baran, Erkan Türker; Department of Biotechnology (2017)
Cues of microenvironment that guide both mature and stem cells determine the success of tissue engineered constructs. To prove and emphasize this expectation, various parameters such as surface topography, scaffold (cell carrier, scaffold) chemistry, 2D vs 3D microenvironments and mechanical stimulation were included into the microenvironment. Surfaces with two distinct physical cues pillar and groove-ridge type micropatterns were transferred to the surfaces of the films by casting the collagen type I and s...
Influence of nanopatterns on endothelial cell adhesion: Enhanced cell retention under shear stress
Zorlutuna, P.; Rong, Z.; Vadgama, P.; Hasırcı, Vasıf Nejat (2009-09-01)
In this study, nanopatterned crosslinked films of collagen Type I were seeded with human microvascular endothelial cells and tested for their suitability for vascular tissue engineering. Since the films will be rolled into tubes with concentric layers of collagen, nutrient transfer through the collagen films is quite crucial. Molecular diffusivity through the collagen films, cell viability, cell proliferation and cell retention following shear stress were studied. Cells were seeded onto linearly nanogrooved...
