Abstract: A method of generating an internally fixed lipid vesicle, comprising: providing a precursor lipid vesicle that contains an aqueous interior enclosed by a lipid membrane, wherein the lipid membrane of the precursor lipid vesicle is non-permeable to a crosslinker; permeabilizing the lipid membrane transiently to generate a permeable vesicle; contacting the permeable vesicle with an inactive activatable crosslinker, whereby the inactive activatable crosslinker enters the permeable vesicle; allowing the permeable vesicle to return to a non-permeable vesicle; removing any extravesicular crosslinker; and activating the inactive activatable crosslinker to allow crosslinking to occur inside the non-permeable vesicle, whereby an internally fixed lipid vesicle is generated.

Abstract: A method of expanding natural killer cells, comprising: providing a population of internally gelated cells, each of which includes a gelated interior and a fluid cell membrane that contains one or more membrane-bound proteins each or collectively are capable of stimulating expansion of natural killer (NK) cells; and culturing a population of cells containing NK cells, which are capable of responding to the one or more membrane-bound proteins, with the population of internally gelated cells under conditions that allow expansion of NK cells.
