20080261306 | Method for Creating Perfusable Microvessel Systems - A method for creating networks of perfusable microvessels in vitro. A mandrel is drawn through a matrix to form a channel through the matrix. Cells are injected into the channel. The matrix is incubated to allow the cells to attach inside the channel. The channel is perfused to remove unattached cells to create a parent vessel, where the parent vessel includes a perfusable hollow channel lined with cells in the matrix. The parent vessel is induced to create sprouts into the surrounding matrix gel so as to form a microvessel network. The microvessel network is subjected to luminal perfusion through the parent vessel. | 10-23-2008 |
20090317787 | METHOD FOR CREATING PERFUSABLE MICROVESSEL SYSTEMS - Creating a tissue structure in vitro includes juxtaposing mandrels on a culture/perfusion device frame where the mandrels are spaced apart substantially parallel to each other and connecting the mandrels to tubes including an upstream tubes and downstream tubes. The upstream tubes are connected with an upstream manifold and the downstream tubes are connected to a downstream manifold. The frame and the mandrels are sterilized, coated and seeded with cells that multiply and form circular layers around each of the mandrels until the circular layers merge into a tissue structure which is subjected to a growth medium. The mandrels are extracted and the tissue structure is perfused. | 12-24-2009 |
