We also disclose a method of propagating primate or human stem cells, the method comprising: providing first and second primate or human stem cells attached to first and second respective particles, allowing the first primate or human stem cell to contact the second primate or human stem cell to form an aggregate of cells and culturing the aggregate to propagate the primate or human stem cells for at least one passage.Type: GrantFiled: November 1, 2010Date of Patent: April 8, 2014Assignee: Agency for Science, Technology and ResearchInventors: Steve Oh, Shaul Reuveny, Allen Chen

Patent number: 8691570Abstract: The present invention discloses novel dendritic cell maturation-inducing cytokine cocktails, and methods for inducting type-1 polarized dendritic cells in serum-free conditions which enhance the desirable properties of DC1s generated in serum-supplemented cultures. The invention further discloses methods and systems using IFN? and other ligands of the IFN? receptor, in combination with IFN? (or other type I interferons), poly I:C, and other IFN? (and IFN?) inducers to enhance the IL-12-producing properties of dendritic cells. More specifically, the present invention discloses type-1 polarized dendritic cells that have a unique combination of a fully-mature status and an elevated, instead of “exhausted”, ability to produce IL-12p70. allows for the generation of fully-mature DC1s in serum-free AIM-V medium.Type: GrantFiled: January 25, 2013Date of Patent: April 8, 2014Inventor: Pawel Kalinski
