  • Patent number: 11299698
    Abstract: The current subject matter includes methods, systems, articles, and techniques to deliver material to anucleate cells, such as red blood cells. Using a rapid deformation based microfluidic system, loading of red blood cells with macromolecules of different sizes has been shown. Although delivery to some mammalian cells, such as cancer cell lines and fibroblasts had been previously demonstrated using this technique, those designs were incompatible with RBCs that have dramatically different physical properties. Through the use of smaller constriction sizes, high speeds and different buffers successful delivery to red blood cells can be achieved. By enabling robust delivery to red blood cells in a simple, scalable manner, the current subject matter can be implemented in a diversity of applications that deliver material to study red blood cell diseases and/or use red blood cells as a therapeutic platform. Related apparatus, systems, techniques, and articles are also described.

  • Patent number: 11253548
    Abstract: A method of producing the constituents of a therapeutic product from mammalian cells is described herein. Cells are isolated from a mammalian source. The cells are exposed to supercritical carbon dioxide (SCCO2) for 1 to 30 minutes, where the SCCO2 is maintained at a pressure of 1071 pounds per square inch (PSI) and a temperature of 31.1 to 45 degrees Celsius during the exposure. The exposure dissociates the cellular membranes of the cells to release intramembrane components therein to produce constituents of the therapeutic product. The mammalian cells may include at least one of platelets, stem cells, germ cells, and somatic cells. The methods described herein are particularly advantageous for releasing and capturing therapeutic intramembrane components from platelets and alpha-granules.
