Microfluidic structures featuring substantially circular channels may be fabricated by embossing polymer sheets.

Microfluidic structures for biomedical applications

Methods and materials for making complex, living, vascularized tissues for organ and tissue replacement, especially complex and/or thick, structures, such as liver tissue is provided. Tissue lamina is made in a system comprising an apparatus having (a) a first mold or polymer scaffold, a semi-permeable membrane, and a second mold or polymer scaffold, wherein the semi-permeable membrane is disposed between the first and second molds or polymer scaffolds, wherein the first and second molds or polymer scaffolds have means defining microchannels positioned toward the semi-permeable membrane, wherein the first and second molds or polymer scaffolds are fastened together; and (b) animal cells. Methods for producing complex, three-dimensional tissues or organs from tissue lamina are also provided.

Fabrication of vascularized tissue using microfabricated two-dimensional molds

The systems and methods described herein relate to a high-throughput flow apparatus. The apparatus is used with an array of wells, and is configured to impart a predetermined shear stress on cells cultured within each of the wells of the array of wells. The apparatus includes a plurality of mechanical tips. The plurality of mechanical tips each includes a head with a hemispheroid shape. The apparatus also includes a motor associated with at least one of plurality of mechanical tips. The motor is configured to drive the plurality of mechanical tips to impart the shear stress pattern in each of the wells.

Systems and method for high-throughput testing

microfluidic structures for biomedical applications

A high-throughput flow system includes an array of wells and a separate mechanical tip positioned within each well. Each mechanical tip is separately actuated to impart a shear stress pattern. A separate sleeve may be associated with each tip for maintaining a predetermined distance between the tip and a floor of the tip's corresponding well, with each tip being rotatable within its corresponding sleeve. Alternatively, a separate post may be associated with each tip for maintaining a predetermined distance between the tip and a floor of the tip's corresponding well, with each tip being rotatable about its corresponding post.

High-throughput biological screening

Methods and materials for making complex, living, vascularized tissues for organ and tissue replacement, especially complex and/or thick structures, such as liver tissue is provided. Tissue lamina is made in a system comprising an apparatus having (a) a first mold or polymer scaffold, a semi-permeable membrane, and a second mold or polymer scaffold, wherein the semi-permeable membrane is disposed between the first and second molds or polymer scaffolds, wherein the first and second molds or polymer scaffolds have means defining microchannels positioned toward the semi-permeable membrane, wherein the first and second molds or polymer scaffolds are fastened together; and (b) animal cells. Methods for producing complex, three-dimensional tissues or organs from tissue lamina are also provided.

Methods and materials for making an apparatus which duplicates the functionality of a physiological system is provided.
