Abstract: A system for identifying irregularities in behaviors of a non-human animal, the system comprising a processing circuitry configured to: provide a behavioral baseline including first information on regular behaviors of the non-human animal over a given period of time when no irregularities occur; obtain data on a series of consecutively identified behaviors of the non-human animal identified over a second period of time; perform an action upon the data not complying with the behavioral baseline, thereby indicating an irregularity in the non-human animal behavior.

Abstract: The invention provides tissue culture system for primary cells (e.g. normal mammalian primary epithelial progenitors). This system includes: a) a serum-free, chemically defined cell culture media; and, b) methods for isolation and in vitro long-term propagation of primary cells (e.g. primary epithelial cells). Primary cells so isolated and cultured can be kept undifferentiated and proliferate for many weeks (>15 weeks) or population doubling (>35 PD) without senescence, or any detectable genetic alterations. Upon changing media/culture conditions, these cells can be induced to differentiate. The invention also provides methods to transform normal primary cells so cultured into “cancer stem cells.” The genetically defined cancer stem cell tumor model mimics the behavior of the disease closely, e.g., the cells are invasive, hormone responsive and metastatic when injected into mice. The tumor cells express genes that are specific to cancer stem cells identified in patient samples.

Abstract: Aspects of the disclosure relate to methods that involve activating the Protein Kinase A (PKA) pathway to induce cancer stem cells (CSCs) to undergo a mesenchymal to epithelial transition. Methods provided herein are useful, in some embodiments, because they render CSCs amenable to treatment with conventional cancer therapies. In some embodiments, methods are provided that involve assaying PKA pathway activity to identify compounds that selectively target CSCs.

Abstract: Aspects of the invention relate to methods and related compositions for preferentially targeting cancer stem cells. In some embodiments, the methods utilize PKC-?/FRA1 pathway inhibitors to target carcinoma cells. Also provided are methods for identifying a candidate compound for selectively inhibiting growth of cancer stem cell, and methods for obtaining cells that have undergone an epithelial to mesenchymal transition.

Abstract: Methods for preparing progenitor cells are described where epithelial cells are induced to undergo epithelial-mesenchymal transition as a result of exposure to an inducing agent or introduction of a gene therein that induces epithelial-mesenchymal transition. Progenitor cells resulting therefrom have use in cell-based therapies, among other utilities.
