BACKGROUND There is an essential demand for tissue engineered autologous small-diameter vascular graft, which can function in arterial high pressure and flow circulation. We investigated the potential to engineer a three-layered robust and elastic artery using a novel hemodynamically-equivalent pulsatile bioreactor. METHODS AND RESULTS Endothelial cells(More)
Injected antigen-loaded immature monocyte-derived dendritic cells (DCs) may be incapable of migrating from skin to draining lymph nodes for antigen presentation. The in vivo migratory capacity of intradermally administered immature monocyte-derived DCs was therefore investigated during a phase I/II clinical trial for metastatic melanoma. DCs cultured from(More)
A 47 year old man undergoing immunotherapy for metastatic melanoma with autologous dendritic cells pulsed with autologous tumour peptide and hepatitis B surface antigen developed acute left ankle arthritis. Gout and acute infection were excluded, and an autoimmune aetiology or occult metastasis were considered. The arthritis initially subsided with(More)
OBJECTIVE Although pancreatic islet transplantation can now be performed minimally invasively in patients with type 1 diabetes, the availability of functional islet donors remains the chief obstacle to widespread clinical application. Tissue engineering islet cells in vitro that function when implanted in vivo provides a solution to this problem. RESEARCH(More)
The regulatory influence of atopic eczema and non-atopic T cells on spontaneous IgE synthesis by eczema B cells was examined. Eczema B cells were cocultured with either autologous or allogeneic T cells in RPMI 1640 with 10% fetal calf serum at 0.75 X 10(6) cells/ml (B/T = 0.5) and supernatant IgE was measured by a modified PRIST assay. Net IgE synthesis was(More)
The effect of dexamethasone (DM) on de novo in vitro total IgE synthesis by blood mononuclear cells (MNC) was studied in atopic patients with eczema and in nonatopic control subjects. Unfractionated blood MNC were cultured at 1 X 10(6) cells per milliliter for 7 days in RPMI 1640 with 10% fetal calf serum with or without decreasing concentrations of DM(More)
Intrinsic cardiac ganglia and their vagal innervation are described from gross and microscopic dissections and functional studies in the anesthetized, open-chest, adult rat. Dissecting microscope sketches of the ventral and dorsal aspects of the rat heart provide gross descriptions of the anatomical course of the vagal cardiac nerves. Histological(More)
