Abstract: The present invention provides phase separation sensors capable of targeting or associating with one or more biomolecular condensate or membraneless compartment in cells. The phase separation sensors comprise at least two domains wherein a first domain comprises one or more accessory protein or molecule and a second domain comprises an artificial client protein or intrinsically disordered sequence. The artificial client protein possesses intrinsic disorder and is capable of engaging in ultra-weak phase separation-specific interactions with one or more component protein or molecule in a biomolecular condensate. Methods and applications utilizing the sensors are provided including targeting, detecting, visualizing, manipulating, monitoring a biomolecular condensate and delivering one or more functional protein, label, drug or agent to a biomolecular condensate.

Abstract: Provided are compositions and methods related to mutations in the Myh9 gene for aiding in diagnosing a subject as having an aggressive form of a cancer, for identifying an individual as a candidate for treatment with a nuclear export inhibitor, for determining whether tumor cells have defective p53 nuclear transportation, and for treating an individual diagnosed with an aggressive cancer.

Abstract: The present invention relates to dermal papilla-specific markers and a method for isolating dermal papilla cells using the same. Dermal papilla cells isolated in accordance with the method of the invention and treated with BMP6 are useful for promoting hair growth.

Abstract: The present invention relates to methods of modulating epithelial stem cell lineage by regulating the expression of Lef1 or a BMP inhibitor and/or the stability of ?-catenin or the expression of a Wnt; regulating the expression or activity of GATA-3; or regulating BMPR1A activity either at the level of receptor expression or at the level of pathway activation. Methods of regulating E-cadherin, GATA-3, BMPR1A and HK1-hair keratin and methods of identifying agents which modulate the epithelial stem cell lineage are further provided. Such agents are useful for inhibiting or stimulating inner root sheath development or hair follicle formation.

Abstract: The present invention relates to methods for isolating infrequently-dividing, slow-cycling cells, a feature which is typical of stem cells in their niche. The methods of the present invention are advantageously used as classical stem cells can be isolated. Further provided are methods for generating clonal populations and inhibiting the differentiation of these cells. In addition markers for distinguishing these cells from progenitor cells are also disclosed.

Abstract: The present invention relates to the use of Lhx2 as a target for modulating the hair growth. Screening assays for identifying agents which increase or decrease the expression or activity of Lhx2 are provided.
