Publication number: 20240076597Abstract: A method for functionalizing a hollow-fiber membrane for cell expansion of targeted cells (e.g., natural killer cells) includes contacting a biotinylating molecule to a surface of the hollow-fiber membrane including an extracellular matrix component, the biotinylating molecule binding to the extracellular matrix component and having an affinity for the targeted cells. The biotinylated molecule may be selected from the group consisting of: cytokine, epitope, ligand, monoclonal antibody, stains, aptamer, and combinations thereof. The extracellular matrix component may be selected from the group consisting of: fibronectin, vitronectin, fibrinogen, collagen, laminin, and combinations thereof.Type: ApplicationFiled: August 16, 2023Publication date: March 7, 2024Applicant: Terumo BCT, Inc.Inventors: Mark E. JONES, Nathan D. FRANK, Mindy M. MILLER, Ann Marie W. CUNNINGHAM, Dalip SETHI

Publication number: 20240060030Abstract: Embodiments described herein generally provide for expanding cells in a cell expansion system. The cells may be grown in a bioreactor, and the cells may be activated by an activator (e.g., a soluble activator complex). Nutrient and gas exchange capabilities of a closed, automated cell expansion system may allow cells to be seeded at reduced cell seeding densities, for example. Parameters of the cell growth environment may be manipulated to load the cells into a particular position in the bioreactor for the efficient exchange of nutrients and gases. System parameters may be adjusted to shear any cell colonies that may form during the expansion phase. Metabolic concentrations may be controlled to improve cell growth and viability. Cell residence in the bioreactor may be controlled. In embodiments, the cells may include T cells. In further embodiments, the cells may include T cell subpopulations, including regulatory T cells (Tregs), for example.Type: ApplicationFiled: August 11, 2023Publication date: February 22, 2024Inventors: Dalip SETHI, James ARTHUR, David Alan HANNA, Daniel CLEMENT, Brian J.

Patent number: 11685883Abstract: Embodiments described herein generally provide for the expansion of cells in a cell expansion system using an active promotion of a coating agent(s) to a cell growth surface. A coating agent may be applied to a surface, such as the cell growth surface of a hollow fiber, by controlling the movement of a fluid in which a coating agent is suspended. Using ultrafiltration, the fluid may be pushed through the pores of a hollow fiber from a first side, e.g., an intracapillary (IC) side, of the hollow fiber to a second side, e.g., an extracapillary (EC) side, while the coating agent is actively promoted to the surface of the hollow fiber. In so doing, the coating agent may be hydrostatically deposited onto a wall, e.g., inner wall, of the hollow fiber.Type: GrantFiled: June 7, 2017Date of Patent: June 27, 2023Assignee: Terumo BCT, Inc.Inventors: Nathan D. Frank, Brian J. Nankervis, Dennis J. Hlavinka, Thomas G. DiLorenzo

Publication number: 20230193180Abstract: Embodiments described herein generally provide for the expansion of cells in a cell expansion system using an active promotion of a coating agent(s) to a cell growth surface in some embodiments. A coating agent may be applied to a surface, such as the cell growth surface of a hollow fiber in a bioreactor, by controlling the movement of a fluid in which a coating agent is suspended, by changing flow rates, by changing flow directions, by rotation of the bioreactor, and/or combinations thereof.Type: ApplicationFiled: February 16, 2023Publication date: June 22, 2023Inventors: Nathan D.

Patent number: 11104874Abstract: Embodiments provide for introducing a first fluid into a bioreactor and while introducing the first fluid into the bioreactor, circulating a second fluid with a reagent at a first flow rate through the bioreactor. The bioreactor may be maintained in a first orientation for a first period of time to allow at least a first portion of the reagent to coat the bioreactor. The second fluid may then be circulated at a second flow rate slower than the first flow rate to allow a second portion of the reagent to coat the bioreactor. Introduction of the first fluid may promote coating of the bioreactor by ultrafiltration. The introduction of the first fluid may be stopped. A third fluid may be circulated through the bioreactor to remove a portion of the reagent not coated on the bioreactor.Type: GrantFiled: June 7, 2017Date of Patent: August 31, 2021Assignee: Terumo BCT, Inc.Inventors: Nathan D.
