Bioartificial ultrafiltration device and methods related thereto

Bioartificial ultrafiltration devices comprising a scaffold comprising a population of cells enclosed in a matrix and disposed adjacent a plurality of channels are provided. The population of cells provides molecules such as therapeutic molecules to a subject in need thereof and is supported by the nutrients filtered in an ultrafiltrate from the blood of the subject. The plurality of channels in the scaffold facilitate the transportation of the ultrafiltrate and exchange of molecules between the ultrafiltrate and the population of cells.

MULTILAYER SEMIPERMEABLE MEMBRANE

The present invention provides a semipermeable membrane which has resistance to oxidizing agents even in the presence of heavy metals and which, despite this, can have salt-removing performance equal to that of semipermeable membranes having poor resistance to oxidizing agents. A coated semipermeable membrane of the invention includes a semipermeable layer and a polymer layer formed on the semipermeable layer, and the polymer layer includes a polymerization product formed by both condensation of hydrolyzable groups possessed by the following compound (A) and polymerization of the compound (A) with the following compound (B): (A) a silicon compound having a silicon atom, a reactive group including an ethylenically unsaturated group directly bonded to the silicon atom, and a hydrolyzable group directly bonded to the silicon atom; and (B) a compound other than the compound (A), which has both a hydrophilic group and an ethylenically unsaturated group.
