Patent number: 12144832Abstract: A method of treating neurodegenerative diseases using hUCB plasma is presented herein. hUCB plasma attenuated the hyperactive response (Group III) and potentiated the normal response in Group I ALS patients, but did not alter that of the non-responders to PHA (Group II). The elevated activity of caspase 3/7 observed in the MNCs from ALS patients was significantly reduced by hUCB plasma treatment. The ability of hUCB plasma to modulate the mitogen cell response and reduce caspase activity suggest that the use of hUCB plasma alone, or with stem cells, may prove useful as a therapeutic in ALS patients. hUCB plasma was shown to increase therapeutic efficacy of MNCs as well as decrease apoptosis of MNCs. The cytokine profile of hUCB plasma supports its usefulness as a sole therapeutic as well as an additive to MNCs.Type: GrantFiled: April 14, 2023Date of Patent: November 19, 2024Assignees: University of South Florida, Saneron CCEL Therapeutics, Inc.Inventors: Svitlana Garbuzova-Davis, Jared Carl Ehrhart, Paul R.

Patent number: 11162075Abstract: The invention provides culture platforms, cell media, and methods of differentiating pluripotent cells into hematopoietic cells. The invention further provides pluripotent stem cell-derived hematopoietic cells generated using the culture platforms and methods disclosed herein, which enable feed-free, monolayer culturing and in the absence of EB formation. Specifically, pluripotent stem cell-derived hematopoietic cell of this invention include, and not limited to, iHSC, definitive hemogenic endothelium, hematopoietic multipotent progenitors, T cell progenitors, NK cell progenitors, T cells, NK cells, NKT cells and B cells.Type: GrantFiled: October 2, 2020Date of Patent: November 2, 2021Assignee: Fate Therapeutics, Inc.Inventors: Bahram Valamehr, Raedun Clarke, Ryan Bjordahl

Patent number: 11028370Abstract: The present invention provides compositions and methods for reprogramming somatic cells using purified RNA preparations comprising single-strand mRNA encoding an iPS cell induction factor. The purified RNA preparations are preferably substantially free of RNA contaminant molecules that: i) would activate an immune response in the somatic cells, ii) would decrease expression of the single-stranded mRNA in the somatic cells, and/or iii) active RNA sensors in the somatic cells. In certain embodiments, the purified RNA preparations are substantially free of partial mRNAs, double-stranded RNAs, un-capped RNA molecules, and/or single-stranded run-on mRNAs.Type: GrantFiled: May 31, 2018Date of Patent: June 8, 2021Inventors: Katalin Kariko, Drew Weissman, Gary Dahl, Anthony Person, Judith Meis, Jerome Jendrisak
