  • Derivation of human embryonic stem cells in xeno-free conditions. 18453244

    Human embryonic stem cells (hESC) have the potential to treat a wide range of diseases. Currently, the use of existing hESC lines in human clinical applications is limited, as they are derived from blastocysts subjected to immunosurgery with animal derived antibodies, and are maintained on mouse embryonic feeder (MEF) cells, in the presence of either fetal calf serum (FCS) or on Matrigel or with conditioned media from MEFs. Successful derivation of hESCs in xeno-free conditions is crucial in advancing stem cell therapy applications. Two hESC lines, one from chromosomally abnormal embryos and another cell line from normal embryos from the inner cell mass of human blastocysts are derived using a culture media that had 20% serum replacement (SR) and human FGF2 on human foreskin fibroblasts as feeder cells. Derivation and characterization of such xenofree hESCs suitable for clinical studies is described in this chapter.

  • The role of nanoparticle concentration-dependent induction of cellular stress in the internalization of non-toxic cationic magnetoliposomes. 19765821

    Magnetoliposomes (MLs), built up of ultrasmall iron oxide cores each individually surrounded by a lipid bilayer, have emerged as highly biocompatible nanoparticles and promising tools in many biomedical applications. To improve cell uptake, cationic amphiphiles are inserted into the ML coat, but this often induces cytotoxic effects. In the present work, we synthesized and tested a cationic peptide-lipid conjugate (dipalmitoylphosphatidylethanolamine-succinyl-tetralysine [DPPE-succ-(Lys)4]) which is entirely composed of biodegradable moieties and specifically designed to exert minimal cytotoxic effects. Uptake studies with both murine 3T3 fibroblasts and C17.2 neural progenitor cells shows 95.63 +/- 5.83 pg Fe and 87.46 +/- 5.62 pg Fe per cell after 24 h, respectively, for 16.66% DPPE-succ-(Lys)4-containing MLs, with no effect on cell viability. However, these high intracellular nanoparticle concentrations transiently affect actin cytoskeleton architecture, formation of focal adhesion complexes and cell proliferation, returning to control levels after approximately 7 days post ML-incubation in both cell types. This study points out the great need for thorough characterization of cell-nanoparticle interactions as subtle time-dependent effects are hard to monitor and commonly used viability and functionality assays are not sufficient to address the broad spectrum of possible interferences of the nanoparticle with normal cell functioning.
