摘要:
Activated human embryos produced by therapeutic cloning can give rise to human totipotent and pluripotent stem cells from which autologous cells for transplantation therapy are derived. The present invention provides methods for producing activated human embryos that can be used to generate totipotent and pluripotent stem cells from which autologous cells and tissues suitable for transplantation can be derived. In one embodiment, the invention provides methods for producing activated human embryos by parthenogenesis; in another embodiment, the invention provides methods for producing activated human embryos by somatic cell nuclear transfer whereby the genetic material of a differentiated human donor cell is reprogrammed to form a diploid human pronucleus capable of directing a cell to generate the stem cells from which autologous, isogenic cells for transplantation therapy are derived. The ability to create autologous human embryos represents a critical step towards generating immune-compatible stem cells that can be used to overcome the problem of immune rejection in regenerative medicine. The activated human embryos produced by the present invention also provide model systems for identifying and analyzing the molecular mechanisms of epigenetic imprinting and the genetic regulation of embryogenesis and development.

摘要:
An improved method of producing differentiated progenitor cells comprising obtaining inner cell mass cells from a blastocyst and inducing differentiation of the inner cell mass cells to produce differentiated progenitor cells. The differentiated progenitor cells may be transfected such that there is an addition, deletion or alteration of a desired gene. The differentiated progenitor cells are useful in cell therapy and as a I source of cells for the production of tissues and organs for transplantation. Also provided is a method of producing a lineage-defective human embryonic stem cell.
摘要:
This invention relates to methods for rejuvenating normal somatic cells and for making normal somatic cells of a different type having the same genotype as a normal somatic cell of interest. These cells have particular application in cell and tissue transplantation. Also encompassed are methods of re-cloning cloned animals, particularly methods where the offspring of cloned mammals are designed to be genetically altered in comparison to their cloned parent, e.g., that are “hyper-young.” These animals should be healthier and possess desirable properties relative to their cloned parent. Also included are methods for activating endogenous telomerase, EPC-1 activity, and or the ALT pathway and/or extending the life-span of a normal somatic cell, and other genes associated with cell aging and proliferation capacity.
摘要:
Embodiments of the disclosure are directed to methods of diagnosis, prognosis and treatment of cancer. In some embodiments, the methods include targeting a marker that is expressed at abnormal levels in bladder cancer tissue in comparison to normal somatic tissue. Some embodiments are directed to methods of treating cancer comprising administering a composition including a therapeutic that affects the expression or function of a target marker. Some embodiments are directed to methods of detecting cancer comprising detecting a level of a target marker associated with the cancer,

The present disclosure generally relates to a multi-component biocide composition comprising a borate component in combination with an azole component to both inhibit mold fungi, decay fungi, such as brown-rot fungi and white-rot fungi, and to resist insect infestation.
摘要:
This invention relates to methods for making immune compatible tissues and cells for the purpose of transplantation and tissue engineering, using the techniques of nuclear transfer and cloning. Also encompassed are methods for determining the effect on immune compatibility of expressed transgenes and other genetic manipulations of the engineered cells and tissues.

A biocide composition comprising (a) about 0.05% to about 75% of an acidic metal salt selected from the metal group consisting of aluminum, iron, manganese, and zirconium; (b) about 0.05% to about 75% of a cationic surfactant; and (c) about 0.0001% to about 25% of an organic biocide.
摘要:
An automated matrix removal module is configurable to automatically withdraw a portion of sample containing an interferent. The module is further configurable to mix the portion of sample with a precipitating reagent selected to react with the interferent to form a precipitant and then filter mixture of sample and precipitant reagent through a filter. Finally, the module is further configurable to flush the precipitant from the filter.
