Abstract: The disclosure provides methods for analysis of disease cell response to a therapeutic agent. In embodiments, a method comprises administering the therapeutic agent to a disease cell sample from the subject in a device that measures at least one physiological parameter of a cell; determining whether a change occurs in the physiologic parameter of the disease cell sample in response to the therapeutic agent as compared to a baseline measurement or the physiological parameter before administration of the therapeutic agent, and selecting the therapeutic agent that results in the change in the at least one physiologic parameter. In embodiments, the disease cells are whole, viable, and/or label free.

Abstract: Provided herein are methods for determining the functional status of a cellular pathway in a diseased cell sample obtained from an individual subject. These methods involve contacting a diseased cell sample obtained from the subject with a perturbing agent (e.g., an activating agent) known to perturb a specific cellular pathway when the pathway is functioning normally. A change in one or more physiological response parameters in the presence of the perturbing agent indicates that the cellular pathway targeted by the perturbing agent is functional in the individual subject. Methods of selecting a targeted therapeutic agent for an individual subject are also provided.
