  • Publication number: 20240150729
    Abstract: The instant invention discloses a closed-system, serum-free, microcarrier-based up-stream process to produce dengue virus. The process comprises a closed-system cell expansion comprising cell passages taking place in closed-system containers. These cell expansions represent a closed process, with replacement media, a cell-detachment agent, and quench medium added though sterile, weldable tubing (a closed-system environment) to eliminate all open aseptic processing following the initial vial thaw of the adherent cells. The viral production takes place in a closed-system bioreactor in adherent cell culture grown on microcarriers providing sufficient cell mass to support the production of dengue virus.

  • Publication number: 20240117315
    Abstract: The present invention provides preparations of MSCs with important therapeutic potential. The MSC cells are non-primary cells with an antigen profile comprising less than about 1.25% CD45+ cells (or less than about 0.75% CD45+), at least about 95% CD105+ cells, and at least about 95% CD166+ cells. Optionally, MSCs of the present preparations are isogenic and can be expanded ex vivo and cryopreserved and thawed, yet maintain a stable and uniform phenotype. Methods are taught here of expanding these MSCs to produce a clinical scale therapeutic preparations and medical uses thereof.
