introduction: failure of human body tissue and organs is believed to be one of the most important health problems all over the world. the great challenge for tissue engineers is to optimize suitable systems to separate, proliferate and differentiate the cells so that they can set out to create tissue by a harmonic 3-d growth. therefore, the tissue engineers must provide an environment like the ...

Foot-and-mouth disease virus (FMDV) causes a highly contagious disease of cloven-hoofed animals. Vaccines require ∼7 days to induce protection; thus, before this time, vaccinated animals are still susceptible to the disease. Our group has previously shown that swine inoculated with 1×10(11) focus forming units (FFU) of a replication-defective human adenovirus containing the gene for porcine int...

Probiotics exhibit beneficial effects on human health, particularly in the maintenance of intestinal homeostasis in a complex manner notwithstanding the diversity of an intestinal flora between individuals. Thus, it is highly probable that some common molecules secreted by probiotic and/or commensal bacteria contribute to the maintenance of intestinal homeostasis and protect the intestinal epit...

The effects of glia conditioned media on the survival and differentiation of embryonic neuron cultures of the Central Nervous System is described. We established glial cultures of peritumoral areas and the culture medium was changed serially and collected as glia conditioned medium (GCM). Neuron enriched cultures plated on poly-L-lysine coated Petri dishes and after 4 days in vitro, the neurona...

CP5 bovine chondrocytes were cultured on biodegradable electrospun fibrous polylactide (PLA) scaffolds placed on a flexible interface formed between two immiscible liquid phases: (1) hydrophobic perfluorochemical (PFC) and (2) aqueous culture medium, as a new way of cartilage implant development. Robust and intensive growth of CP5 cells was achieved in our hybrid liquid-solid-liquid culture sys...

Maintenance of liver-specific function of hepatocytes in culture is still difficult. Improved culture conditions may enhance the cell growth and function of cultured cells. We investigated the effect of three-dimensional culture under flow conditions, and the influence of surface modifications in hepatocyte cultures. Hepatocytes were harvested from Lewis rats. Cells were cultured on three-dimen...
