Stem Cell Related Patent Number US5340744
Title: | Method of identifying and modulating the activity of label retaining cells in hair follicles for diagnostic and therapeutic purposes | Inventors: | Lavker, Robert M.; Malvern, PA, USA
Sun, Tung-Tien; Scarsdale, NY, USA
Cotsarelis, George; Upper Darby, PA, USA | Summary: | This invention describes methods of identifying and modulating the activity of label-retaining stem cells that are found in self-renewing tissue such as hair follicles. Described herein are methods by which the activity of slow-cycling cells may be modulated and the efficacy of agents may be evaluated for their ability to modulate the activity of stem cell populations. Further disclosed are methods by which cells that are continuously labeled may be induced into a proliferative phase by exposure to an agent such as TPA or a cytokine, and then observed in relation to established criteria. Therapeutic applications are included for the diagnosis and treatment of abnormal hair growth and skin cancers. This invention represents a continuation of other applications filed by the same assignees. | Abstract: | Methods of detecting label retaining cells in self-renewing tissues, such as hair follicle, are provided. Methods of modulating the activity of slow-cycling cells and methods of evaluating the efficacy of agents for modulating the activity of stem cell populations are also provided. Generally, cells are continuously labeled, induced into a proliferative phase by exposure to an agent such as TPA or a cytokine, and then observed in relation to established criteria. | US Patent Website: | Click Here for Full Text of Patent | Title Number: | US5340744 | Application Number: | US1993000135051 | Date Filed: | 12/10/1993 | Date Published: | 23/08/1994 | Assignee: | Trustees of the University of Pennsylvania, Philadelphia, PA, USA
