Patent number: 8748180Abstract: A microfluidic device for culturing cells, termed a microscale cell culture analog (?CCA), is provided. The microfluidic device allows multiple cell or tissue types to be cultured in a physiologically relevant environment, facilitates high-throughput operation and can be used for drug discovery. The microfluidic device uses gravity-induced fluidic flow, eliminating the need for a pump and preventing formation of air bubbles. Reciprocating motion between a pair of connected reservoirs is used to effect the gravity-induced flow in microfluidic channels. Bacterial contamination is reduced and high throughput enabled by eliminating a pump. The microfluidic device integrates a pharmacokinetic-pharmacodynamic (PK-PD) model to enable PK-PD analyses on-chip. This combined in vitro/in silico system enables prediction of drug toxicity in a more realistic manner than conventional in vitro systems.Type: GrantFiled: July 29, 2010Date of Patent: June 10, 2014Assignee: Cornell UniversityInventors: Michael L. Shuler, Jong Hwan Sung

Publication number: 20110012638Abstract: A device is disclosed in one embodiment that has multiple identical sets of programmable functional elements, programmable routing resources, and majority voters that correct errors. The voters accept a mode input for a redundancy mode and a split mode. In the redundancy mode, the programmable functional elements are identical and are programmed identically so the voters produce an output corresponding to the majority of inputs that agree. In a split mode, each voter selects a particular programmable functional element output as the output of the voter. Therefore, in the split mode, the programmable functional elements can perform different functions, operate independently, and/or be connected together to process different parts of the same problem.Type: ApplicationFiled: July 14, 2009Publication date: January 20, 2011Inventor: Robert L.

Patent number: 5942421Abstract: A single celled organism, vector, and method are provided for continuous production of excreted proteins in the absence of substantial host cell replication and without the necessity for the addition of antibiotics to control cell replication. The vector has (1) an inducible promoter capable of activating a gene for a protein to be produced under conditions that substantially inhibit host cell replication, and (2) a hybrid gene containing a signal sequence fused to a gene for the protein to be produced. Large quantities of the transformed single celled organisms containing the vector can be grown in the absence of inducing conditions, thereby reducing the problem of plasmid loss. Further, the protein is produced under conditions that substantially inhibit host cell replication, thereby allowing immobilization of the single celled organism by entrapment or attachment within or onto a solid support surface. The single celled organism can be immobilized after, before or simultaneously with induction.Type: GrantFiled: November 18, 1997Date of Patent: August 24, 1999Assignee: Cornell Research Foundation, Inc.Inventors: Michael L. Shuler, David B. Wilson

Patent number: 5728580Abstract: Non-carboxylated sulfated polyanions have been successfully used to rapidly obtain and maintain stable single-cell suspension of BTI-TN5B1-4 cells, a cell line which has a high intrinsic capacity for the expression of recombinant protein, but which clumps severely in suspension reducing its effectiveness as a host for foreign protein production with the baculovirus expression vector system. The three most effective polyanions for inducing a single-cell suspension were dextran sulfate, polyvinyl sulfate, and pentosan sulfate. The cost of dextran sulfate treatment is low compared to heparin treatment, which required a 20-fold higher lever to induce single-cell suspension. More importantly, dextran sulfate does not block vital infection at MOI.gtoreq.1 whereas heparin is known to seriously inhibit infection.Type: GrantFiled: February 20, 1996Date of Patent: March 17, 1998Assignee: Cornell Research Foundation, Inc.Inventors: Michael L.

Patent number: 5612188Abstract: The present invention relates to an in vitro system for physiological and metabolic evaluation of substances for use in living beings. The system includes one or more cell culture chambers, each containing cells in a culture medium and a gas-liquid exchange device for contacting the culture medium with oxygen-containing gas so that the culture medium absorbs that gas and desorbs carbon dioxide-containing gas. The conduit system conducts culture medium between the gas-liquid exchange device and the cell culture chambers. A circulation mechanism is used to circulate culture medium through the conduit system, the cell culture chambers, and the gas-liquid exchange device. In use, the substance to be evaluated is added to the culture medium of the system and circulated through the system. The cells in each of the cell culture chambers are then evaluated for effects resulting from the presence of the substance.Type: GrantFiled: February 10, 1994Date of Patent: March 18, 1997Assignee: Cornell Research Foundation, Inc.Inventors: Michael L.

Patent number: 5244794Abstract: Root organ cultures of the monocot genus Allium were successfully grown in culture medium. In a preferred bioreactor system, the roots themselves can be grown and harvested as a source of various Allium flavors and/or the growing roots can be reacted with various nutrients to produce Allium flavor compounds independent of the root harvesting. The root cultures of the present invention produce quantities of onion and onion-like flavor compounds comparable to those found in onion bulbs.Flavor precursors arThis invention was made in part under NSF Grant No. 85-03183. The U.S. Government has certain rights to this invention.Type: GrantFiled: June 28, 1991Date of Patent: September 14, 1993Assignee: Cornell Research Foundation, Inc.Inventors: Christopher Prince, Michael L.
