A method of treating biocells includes the steps of: a. providing biocells b. applying at least one stressor to the biocells sufficient to cause nonlethal and reparable cell wall damage to the biocells, thereby putting the biocells in a catabolic state during which catabolic metabolic functions predominate over anabolic metabolic functions and c. obtaining at least one product produced by the biocells during the catabolic state. In another embodiment, the method includes the steps of: a. providing biocells that are mammalian cells b. applying at least one stressor to the biocells sufficient to cause nonlethal and reparable cell wall damage to the biocells, the reparable cell wall damage comprising openings that allow increased passage of materials through the cells walls and c. inserting foreign DNA through the openings into the biocells.
