Methods for characterizing tissue or organ condition or status
First Claim
1. A method for characterizing the condition of a tissue or organ in an animal, comprising determining a composite clinical score of said tissue or organ, wherein said composite clinical score is determined based on a plurality of k clinical measures of said tissue or organ of said animal.

Abstract
The invention provides methods for characterizing the condition or status of a tissue or organ in a multicellular organism, e.g., an animal, by combining a plurality of clinical measures are combined into a composite clinical score (CCS) and using such a CCS to represent the condition or status of the tissue or organ. The invention provides methods for predicting the condition or status of a tissue or organ in a multicellular organism, e.g., an animal, based on measurements of a set of cellular constituent markers, e.g., measured expression levels of a set of marker genes. The invention also provides methods for selecting the set of marker genes whose expression levels can be used in determining the CCS.

(b) comparing said composite clinical score determined in step (a) to (b1) standard values of said composite clinical score indicating condition of said tissue or organ;
or (b2) a composite clinical score determined based on a second cellular constituent profile of said tissue or organ, wherein said second cellular constituent profile comprises measurements of said plurality of cellular constituents in cells of said tissue or organ before administration of said drug to said animal;
thereby evaluating the efficacy of said drug in treating said disease. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)

- 57. A method for determining a model estimator for characterizing a condition of a tissue or organ in an animal, comprising using a plurality of cellular constituent profiles, each comprising measurements of a plurality of cellular constituents, to train a model estimator, said model estimator outputting a composite clinical score using said measurements of said plurality of cellular constituents in a cellular constituent profile, wherein each of said profiles is obtained from said tissue or organ under a different given condition, and wherein each of said profiles has an associated composite clinical score, said composite clinical score being generated using a plurality of clinical measures of said tissue or organ of said animal.

85. A method of determining hepatotoxicity of a compound at a given dosage in an animal, comprising
(a) contacting hepatocytic cells of said animal with said compound at said dosage; -
(b) measuring a cellular constituent profile, wherein said cellular constituent profile comprises measurements of a plurality of cellular constituents in said hepatocytic cells;
(c) determining a composite clinical score of said hepatocytic cells based on said cellular constituent profile; and
(d) determining said compound as having hepatotoxicity if said composite clinical score is above a threshold value. - View Dependent Claims (86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100)
