  • Patent number: 11040071
    Abstract: The present invention offers a solution to the lack of an effective alternative method to those already known to treat angiogenesis. In particular, the present invention is the first to show that a substantially pure population of exosomes derived from MenSCs have capacity to reduce tumor angiogenesis in diseases such as prostate cancer, breast cancer and pancreatic cancer. In this sense, the present invention shows that a substantially pure population of MenSCs-derived exosomes reduce the endogenous levels of reactive oxygen species (ROS) in cancer cells and the expression of pro-angiogenic factors such as VEGF, NF-KB, FGF and HIF? in the treated tumors. Overall, the invention offers a promising alternative method to treat angiogenesis. Since it is principally composed of exosomes produced by the Stem cells present in menstrual fluid, the invention provides an ease access and repeated sampling in a non-invasive manner. Such attributes allow the rapid production of the treatment.

  • Patent number: 10688694
    Abstract: The present invention overcomes all the above drawbacks and provides a versatile method for the fabrication of multilayer hollow tubes that uses a layer-by-layer rod dipping approach using different biomaterials. The device enables fine control over fabrication parameters, such as ascending/descending speeds, rod rotational velocity, and crosslinking or polymerization time. All these technologies allows the generation of more complex multilayer hollow tubes such as vessel-like structures, urethral grafting, prostate grafting and the like.

  • Publication number: 20180303878
    Abstract: The present invention offers a solution to the lack of effective alternative treatments to fight infectious disease, preferably involving sepsis, comprising active ingredients obtained by non-intrusive and efficient methods. In particular, the present invention is the first to show that mesenchymal stem cells obtained from menstrual fluids (MenSCs) have the capacity to control infectious diseases, especially those leading to a reaction of the host body like sepsis. As shown herein, in vivo experiments illustrate that MenSCs have antibacterial activity in vitro, increase the survival rates of a mouse model for sepsis, regulate several parameters that are altered in sepsis patients and that are related with multi-organ dysfunction, such as the levels of Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), alkaline phosphatase (ALP), glucose in blood, serum albumin, lung injury.

  • Publication number: 20170143764
    Abstract: A method and compound product are created from menstrual blood-derived mesenchymal stem cells (MenSCs) with an anti-tumor effect. In particular, the method and compound show the potential anti-tumor effect MenSCs can have on human pancreatic carcinoma, which has been analyzed on the Mia PaCa 2 human pancreatic carcinoma cell line (ATCC #CRL 1420). MenSCs have been proven to have an in vitro anti-tumor effect both in bi-dimensional cultures (monolayer) and in three-dimensional cultures (tumorspheres). Additionally, MenSCs slow down the appearance of pancreatic tumors when they are co-implanted with the pancreatic carcinoma cell line. MenSCs also have an in vivo therapeutic advantage in the treatment of human pancreatic carcinoma via intra-tumor injections.

  • Publication number: 20160193250
    Abstract: The present invention relates to a method for providing chorion cells as a source of MSCs with cardio-myogenic and angiogenic potential, the use of these cells in clinical treatment, the obtaining of a conditioned medium of chorion-MSCs cells as inducer of angiogenesis and its use in tube-like structures generation and cardiac regeneration as an alternative to bone marrow cells in the treatment of degenerative conditions.

  • Publication number: 20160024473
    Abstract: The invention relates to highly proliferative stem cell obtained from menstrual fluid. The menstrual stern cells (MenSCs) may be cultured in vitro and exhibit mesenchymal stem cell (MSC)-like properties and some culture and expansion advantages. This population of MenSCs, compared to the broadly studied bone marrow derived stem cells (BM-MSCs) out-performs bone marrow derived mesenchymal stem cells in proliferation rate and support of hematopoietic stem cell (HSC) expansion in vitro. MenSCs demonstrate to maintain their stem cell properties over 2 years, being genetically stable, without expressing surface differentiation markers, and they also show the ability to differentiate into adipocytes, chondrocytes and osteoblast cells. MenSCs can be easily and periodically obtained, isolated and cultured.

  • Publication number: 20150007357
    Abstract: The invention is directed to a method of determining whether an agent causes immune toxicity in a human comprising administering the agent to a non-human mammal that has been engrafted with human hematopoietic stem cells (HSCs) and administered one or more human cytokines; and determining whether the agent causes immune toxicity in the non-human mammal. If the agent causes immune toxicity in the non-human mammal then the agent causes toxicity in a human. The invention is also directed to a method of determining whether administration of an agent causes cytokine release syndrome in an individual in need thereof comprising administering the agent to a non-human mammal that has been engrafted with HSCs and administered one or more human cytokines; and determining whether the agent causes cytokine release syndrome in the non-human mammal. If the agent causes cytokine release syndrome in the non-human mammal then the agent will cause cytokine release syndrome in the human.
