  • Publication number: 20170035938
    Abstract: Disclosed are methods of obtaining an expanded population of mammalian ex vivo cells for treating a mammalian subject by (a) administering to a subject an effective amount of an agent that confers a growth disadvantage to at least a subset of endogenous cells at the site of engraftment; (b) administering to the subject an effective amount of a mitogenic stimulus for the ex vivo cells; and (c) administering the ex vivo cells to the subject, wherein the ex vivo cells engraft at the site and proliferate to a greater extent than the subset of endogenous cells, to repopulate at least a portion of the engraftment site with the ex vivo cells. The repopulated cells can be harvested or left at the engraftment site. Methods of treating brain injury in a subject by engrafting ex vivo cells at the site of injury are also described.

  • Publication number: 20170014651
    Abstract: A method of diagnosis and treatment of tumors using High Intensity Focused Ultrasound is provided. The method of diagnosing the presence of a tumor in a patient comprises the steps of subjecting a tumor to high intensity focused ultrasound (HIFU) to cause the tumor cells to release cellular material and evaluating the cellular material for a tumor marker. The method of treating a tumor in a patient can also comprise the step of subjecting a tumor to high intensity focused ultrasound (HIFU) to provoke an immune response.

  • Publication number: 20160230139
    Abstract: The invention disclosed herein aims to standardize and simplify the process of preparing Ex-Vivo autologous whole tumor cell vaccines. The present invention is a robust, stand-alone device and system for preparing autologous tumor cell vaccines in a completely self-contained sterile environment, and in a shortened time. This new device and system will process the extracted tumor with its associated stromal and endothelial cells into injectable tumor cell vaccines, administered automatically or semi-automatically. This invention incorporates a number of new biotechnologies to enhance therapeutic effects over other existing methods. This invention will allow a medical facility to prepare and administer autologous cancer cell vaccine therapy independently without having, or using, a GMP facility, while adhering to and maintaining GMP guidelines.

  • Publication number: 20160074400
    Abstract: Provided are composition and methods for treating radiation-induced cell damage, and in particular aspects to methods for protecting, mitigating or otherwise treating radiation-induced induced depletion of tissue stem cells and injury to the supportive stem cell niche, and in even more particular aspects to methods for protecting, mitigating or otherwise treating radiation-induced gastrointestinal syndrome (RIGS), comprising sequential administration of a Wnt pathway activator/agonist (e.g., Rspo1 or a small molecule inducer thereof) that amplifies the surviving intestinal stem cell (ISC) pool post-radiation exposure, followed by a selective antagonist of the ?-Catenin-CBP interaction (e.g., ICG-001 or other exemplary compounds disclosed herein) that accelerates differentiation of the stimulated (e.g., Rspo1-stimulated) ISC in crypt-villi axis, promoting villous regeneration and intestinal restitution, thereby mitigating RIGS. Adjunctive and combination therapy embodiments are encompassed.
