Compositions and methods for multiplexed quantitative analysis of cell lineages
Abstract
Compositions and methods are provided for measuring population size for a plurality of clonal cell populations in the same individual, e.g., for measuring tumor size for a plurality of clonally independent tumors within the same individual. A subject method can include: (a) contacting an individual with a plurality of cell markers that are heritable and distinguishable from one another, to generate a plurality of distinguishable lineages of heritably marked cells; (b) after sufficient time has passed for the heritably marked cells to undergo at least one round of division, detecting and measuring quantities of at least two of the plurality of cell markers present in the contacted tissue, thereby generating a set of measured values; and (c) using the set of measured values to calculate the number of heritably marked cells that are present (e.g., for at least two of the distinguishable lineages of heritably marked cells).

41 . The method of claim 32 , wherein the barcodcd nucleic acids are linear or circular DNA molecules.
42 . The method of claim 32 , wherein the barcodcd nucleic acids are selected from: plasmids, synthesized nucleic acid fragments, and minicircles.
43 . The method of claim 32 , wherein the barcodcd nucleic acids are RNA/DNA hybrids or nucleic acid/protein complexes.
44 . The method of claim 32 , wherein the tissue is an invertebrate tissue.
45 . The method of claim 32 , wherein the tissue is a vertebrate tissue.
46 . The method of claim 32 , wherein the tissue is a mammalian or a fish tissue.
47 . The method of claim 32 , wherein the tissue is a rat tissue, a mouse tissue, a pig tissue, a non-human primate tissue, or a human tissue.
48 . The method of claim 32 , wherein the tissue is part of a living animal.
49 . The method of claim 32 , wherein the tissue is an engineered tissue grown outside of an animal.
50 . The method of claim 32 , wherein the tissue is selected from: muscle, lung, bronchus, pancreas, breast, liver, bile duct, gallbladder, kidney, spleen, blood, gut, brain, bone, bladder, prostate, ovary, eye, nose, tongue, mouth, pharynx, larynx, thyroid, fat, esophagus, stomach, small intestine, colon, rectum, adrenal gland, soft tissue, smooth muscle, vasculature, cartilage, lymphatics, prostate, heart, skin, retina, reproductive system, and genital system.
51 . The method of claim 32 , wherein after sufficient time has passed for at least a portion of the heritably marked neoplastic cells to undergo at least one round of division, the method further comprises: (i) detecting and/or measuring a biomarker of the heritably marked neoplastic cells, and (ii) categorizing the heritably marked neoplastic cells based on the results of said detecting and/or measuring of the biomarker.
52 . The method of claim 51 , wherein the biomarker one or more of: cell proliferation status, cell type, developmental cell lineage, cell death, or cellular signaling state.
