| Title: | Inducible HSV-TK in transformed cell populations | | Inventors: | Evans, Ronald M.; La Jolla, CA, USA

Heyman, Richard Alan; Encinitas, CA, USA | | Summary: | This invention describes a method of selectively inhibiting the growth of a tissue-type or cell line, via the administration of a latent toxin that triggers generation of the cell toxin by enzymatic conversion of the latent toxin. The invention relates to a new method of selection for inducibly and genetically ablating specific cell lineages in transgenic cell populations and in transgenic animals. The new method is described as permitting the production of stable transgenic perigees, useful at various stages of development of a transgenic cell population, and which allows both the timing and the degree of cellular ablation to be controlled. Applications are included in the study of cell lineages and organogeneis, especially in immunological disorders. | | Abstract: | The present invention discloses a new selective method for inducibly and genetically ablating specific cell lineages in transgenic cell populations, e.g., in transgenic animals. The new method, which permits the production of stable transgenic perigees, and thus can be used at various stages of development of a transgenic cell population, allows both the timing and the degree of cellular ablation to be controlled. As a result the method can be used for a variety of therapeutic applications, as well as to study cell lineages and organogenesis, plus the capacity that residual stem cells have for regeneration. | | US Patent Website: | Click Here for Full Text of Patent | | Title Number: | US6677311 | | Application Number: | US1995000464271 | | Date Filed: | 05/06/1995 | | Date Published: | 13/01/2004 | | Assignee: | The Salk Institute for Biological Studies, La Jolla, CA, USA |
