AbstractThe creation of an in vitro functional tendon construct will enable testing of the influence of mechanics and nutrients on the development and remodeling of tendon under known controlled stimuli which is difficult to achieve in vivo. Tendon constructs were engineered in vitrovia stress-mediated self organization of fibroblasts and ECM on a laminin coated elastomer substrate. Varying the laminin density and the amount of fetal bovine serum on the substrate affected the ability of tendon fibroblasts to form a confluent cell layer and the time to layer delamination. Understanding the factors that promote self-assembly of tendon constructs will enable their combination with already developed in vitro muscle constructs.

Recent advances applying mammalian tissue engineering to in vitro plant cell culture have successfully cultured single plant cells in a 3D microstructure, leading to the discovery of plant cell behaviours that were previously not envisaged. Animal and plant cells share a number of properties that rely on a hierarchical microenvironment for creating complex tissues. Both mammalian tissue engineering and 3D plant culture employ tailored scaffolds that alter a cell's behaviour from the initial culture used for seeding. For humans, these techniques are revolutionizing healthcare strategies, particularly in regenerative medicine and cancer studies. For plants, we predict applications both in fundamental research to study morphogenesis and for synthetic biology in the agri-biotech sector.

To study the role of sulfhydryl group formation during cell cycle progression, mammalian tissue culture cells (PTK2) were exposed to 100¼M 2-mercaptoethanol for 2 to 6 h during their exponential phase of growth. The effects of 2-mercaptoethanol on centrosomes, chromosomes, microtubules, membranes and intermediate filaments were analyzed by transmission electron microscopy (TEM) and by immunofluorescence microscopy (IFM) methods using a human autoimmune antibody directed against centrosomes (SPJ), and a mouse monoclonal antibody directed against tubulin (E7). Chromosomes were affected most by this treatment: premature chromosome condensation was detected in interphase nuclei, and the structure in mitotic chromosomes was altered compared to control cells. This would support previous findings in dividing sea urchin cells in which chromosomes are arrested at metaphase while the centrosome splitting cycle continues. It might also support findings that certairt-sulfhydryl-blocking agents block cyclin destruction. The organization of the microtubule network was scattered probably due to a looser organization of centrosomal material at the interphase centers and at the mitotic poles.
