Endothelial cells enhance the in vivo bone-forming ability of osteogenic cell s...
Pirraco, Rogério; Iwata, Takanori; Yoshida, T.; Marques, A.; Yamato, Masayuki; Reis, R. L.; Okano, T.Addressing the problem of vascularization is of vital importance when engineering three-dimensional (3D) tissues. Endothelial cells are increasingly used in tissue-engineered constructs to obtain prevascularization and to enhance in vivo neovascularization. Rat bone marrow stromal cells were cultured in thermoresponsive dishes under osteogenic conditions with human umbilical vein endothelial cells (HUVECs) to o...
Development of osteogenic cell sheets for bone tissue engineering applications
Pirraco, Rogério; Obokata, Haruko; Iwata, Takanori; Marques, A. P.; Tsuneda, Satoshi; Yamato, Masayuki; Reis, R. L.; Okano, T.The use of scaffolds in combination with osteogenic cells has been the gold standard in bone tissue engineering strategies. These strategies have, however, in many cases failed to produce the desired results due to issues such as the immunogenicity of the biomaterials used and cell necrosis at the bulk of the scaffold related to deficient oxygen and nutrients diffusion. Here, we originally propose the use of ce...

Development and characterization of osteogenic cell sheets in an in vivo model
Pirraco, R. P.; Yamato, M.; Marques, A. P.; Reis, R. L.; Okano, T.[Excerpt] Despite some successes in the tissue engineering field its evolution seems to be tampered by limitations such as cell sourcing and the lack of adequate scaffolds to support cell growth and differentiation. The use of stem cells combined with cell sheet engineering technology seems a promising way to overcome these limitations. In this work bone marrow cells were flushed from 3 weeks old Wistar rat fem...
Perceptions of postnatal depression across countries and cultures: from a Trans...
Glangeaud-Freudenthal, N.; Asten, P.; Ghubash, R.; Smith, M.; Cox, J. L.; Figueiredo, Bárbara; Gorman, L. L.; Hacking, S.; Hirst, E.; Kammerer, M. H.Objectives The qualitative study was conducted within the international “Transcultural study of postnatal depression (PND)” in 17 centres located in 13 different countries. The aim was to explore perceptions of PND by lay and professional key informants, specifically regarding description of symptoms, awareness of this pathology and of possible care. Methods Broad areas of inquiry and open-ended probes were dev...
