Abstract:
It is an object of the present invention to establish a system for reliably differentiating an ES cell into a hepatic cell. The present invention provides a method for inducing the differentiation of an ES cell into a hepatic cell, which comprises, in the presence of an M15 cell, culturing a mammal-derived ES cell in the presence of activin and bFGF, and then culturing the ES cell in the presence of dexamethasone, HGF, and oncostatin M.
Abstract:
The invention concerns a method for producing cryopreserved bovine embryos from bred oocytes in vitro comprising the following steps: 1) maturing and breeding bovine oocytes in vitro; 2) culturing in vitro said bred oocytes until the morula or blastocyst stage; 3) selecting quality 1 embryos; 4) freezing the selected embryos. The culturing step (2) is a co-culture on a mat of Vero cells carried out serum-free, and the freezing step (4) is carried out while the embryo is conditioned in a freezing medium containing a glycerol-trehalose mixture as cryoprotectant.
Abstract:
There is provided a method of culturing a stem cell on extracellular matrix extracted from support cells and in a stem cell culture medium comprising medium conditioned by the support cells
Abstract:
A normal regenerated tissue is formed by exposing to radiation a connective tissue or a supporting tissue originating in an organ to thereby form a feeder layer and then transplanting epithelial cells thereon to form a stratified structure. By conveniently and surely providing regenerated tissue by the 3-dimensional culture with the use of a human-origin normal tissue as a base, it is possible to construct systems for assessing effects and side effects of chemicals such as drugs or assessing sensitivities thereof with the use of regenerated tissues as models of corresponding tissues respectively.
Abstract:
The present invention generally relates to the field of diagnostic microbiology, and, more particularly, to the compositions and methods for detecting and differentiating one or more viruses or other intracellular parasites present in a specimen. The present invention also provides kits comprising the compositions for detecting and differentiating one or more viruses or other intracellular parasites.

Abstract:
Disclosed are renal tissues and arrays thereof that include a layer of renal interstitial tissue, the renal interstitial tissue comprising renal fibroblasts and endothelial cells; and a layer of renal epithelial tissue, the renal epithelial tissue comprising renal tubular epithelial cells, the renal epithelial tissue in contact with the layer of renal interstitial tissue to form a three-dimensional, engineered, biological renal tissue. Also disclosed are methods of fabricating and using the same.

The present invention generally relates to the field of diagnostic microbiology, and, more particularly, to compositions and methods for detecting and differentiating one or more viruses or other intracellular parasites present in a specimen. The present invention also provides compositions and methods to evaluate the susceptibility of an organism to antimicrobial agents.
Abstract:
A novel cell seeded hollow fiber bioreactor is described as a potential bioartificial kidney. Renal cells are seeded along a hollow fiber in a perfused bioreactor to reproduce the ultrafiltration function and transport function of the kidney. Maintenance of tissue specific function and ultrastructure suggest that this bioreactor provides an economical device for treating renal failure as well as studying renal tubululogenesis in vitro.
