A system and method for forming a ligament construct using fibrogenic media and a system and method for forming a functionally integrated bone-ligament construct are also provided.Type: GrantFiled: February 4, 2008Date of Patent: July 1, 2014Assignee: The Regents of the University of MichiganInventors: Ellen M. Arruda, Lisa M. Larkin, Fatima N. Syed-Picard, Michael Smietana, Jinjin Ma

Patent number: 8759096Abstract: Disclosed is a microfluidic chip and method using the same. The microfluidic chip comprises a substrate having a surface, and at least a tissue culture area formed on the surface of the substrate. The tissue culture area has a microfluidic channel formed by a plurality of connected geometrical structures (nozzle-type channels) having a predetermined depth. The microfluidic channel has an inlet and an outlet, which are at two ends of the microfluidic channel, for medium inputting and outputting, respectively. Additionally, at least an air-exchange hole is formed on the bottom of the microfluidic channel. By using the microfluidic chip for tissue culture, lateral flow speed and stress can be decreased, so as to prolong survival time of tissues (e.g. liver tissues).Type: GrantFiled: May 7, 2010Date of Patent: June 24, 2014Assignee: National Tsing Hua UniversityInventors: Chen-Wei Wu, Cheng-Hsien Liu, Chau-Ting Yeh, Hui-Ling Lin, Hsin-Yu Lai, Tzu-Chi Yu

Patent number: 8759014Abstract: The invention provides a method of obtaining a population of antigen-specific T cells from peripheral blood of a host. An embodiment of the method of the invention comprises (i) dividing PBMCs from peripheral blood of a host into more than one sub-population; (ii) contacting the PBMCs with an antigen and IL-2; (iii) obtaining a sample of PBMCs from each sub-population; (iv) identifying an antigen-reactive sub-population by determining by high throughput quantitative PCR the expression of a factor produced by the PBMCs of each sample; (v) dividing the antigen-reactive sub-population into microcultures; (vi) identifying the antigen-reactive microculture; and (vii) expanding the microculture, thereby obtaining a population of T cells specific for the antigen. The invention also provides a population of T cells obtained by the inventive method, a pharmaceutical composition comprising the same, and a method of treating a disease in a host using the pharmaceutical composition.Type: GrantFiled: February 10, 2009Date of Patent: June 24, 2014Assignee: The United States of America, as represented by the Secretary, Department of Health and Human ServicesInventor: Udai S.

Publication number: 20140154281Abstract: As discussed in greater detail herein, isolated epitope peptides derived from MPHOSPH1 bind to an HLA antigen and induce cytotoxic T lymphocytes (CTL) and thus are suitable for use in the context of cancer immunotherapy, more particularly cancer vaccines. The inventive peptides encompass both the above-mentioned MPHOSPH1-derived amino acid sequences and modified versions thereof, in which one, two, or several amino acids are substituted, deleted, inserted or added, provided such modified versions retain the requisite CTL inducibility of the original sequences. Further provided are polynucleotides encoding any of the aforementioned peptides as well as pharmaceutical agents or compositions that include any of the aforementioned peptides or polynucleotides.Type: ApplicationFiled: August 9, 2012Publication date: June 5, 2014Applicant: Onco Therapy Science, Inc.Inventors: Takuya Tsunoda, Ryuji Osawa, Sachiko Yoshimura, Tomohisa Watanabe, Yusuke Nakamura
