  • Patent number: 12590849
    Abstract: A temperature exposure indicator includes a reservoir of meltable material having a melting point at an activation threshold of the temperature exposure indicator. The temperature exposure indicator also includes a light scattering material having voids and an indicia overlayed by the light scattering material such that the indicia is initially obscured by the light scattering material prior to the meltable material being exposed to a temperature above the activation threshold. The reservoir is in fluid communication with the light scattering material, such that the meltable material, when exposed to a temperature at or above the activation threshold, is configured to melt and flow into the voids of the light scattering material thereby causing the light scattering material to transition from an obscuring form to a non-obscuring form so that the indicia is viewable through the light scattering material.

  • Publication number: 20260000763
    Abstract: Provided are methods of manufacturing cells. The methods comprise expanding cells in the presence of inosine, and harvesting the cells after expansion. In certain embodiments, the cells are genetically modified. For example, the cells may be genetically modified to express an engineered receptor, non-limiting examples of which are chimeric antigen receptors (CARs), engineered T cell receptors (TCRs), and the like. According to some embodiments, the cells are immune cells, e.g., T cells or natural killer cells. Also provided are populations of cells manufactured according to the methods of the present disclosure. Also provided are methods comprising administering an effective amount of a population of cells manufactured according to the methods of the present disclosure to a subject in need thereof. In certain embodiments, the subject has cancer, and the cells express an engineered receptor that binds to a tumor antigen on the surface of cells of the cancer.
