Prochymal
Prochymal is a stem cell therapy made by Osiris Therapeutics. It is the first stem cell therapy approved by Canada. It is also the first therapy approved by Canada for acute graft-vs-host disease (GvHD). Also known as remestemcel-L, Prochymal was sold to Australia-based Mesoblast in 2013 at which time its brand name was changed to Ryoncil. It is an allogeneic stem therapy based on mesenchymal stem cells (also medicinal signalling cells, mesenchymal stromal cells, and MSCs) derived from the bone marrow of adult donors. MSCs are purified from the marrow, cultured and packaged, with up to 10,000 doses derived from a single donor. The doses are stored frozen until needed. Approvals and indications In May 2012 Health Canada approved the use of remestemcel-L (Prochymal) for the management of acute GvHD in children who are unresponsive to steroids, with the approval conditional upon further trials being conducted. Separately, a pilot study of Ryoncil on ventilator-assisted COVID ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stem Cell Therapy
Stem-cell therapy is the use of stem cells to treat or prevent a disease or condition. , the only established therapy using stem cells is hematopoietic stem cell transplantation. This usually takes the form of a bone-marrow transplantation, but the cells can also be derived from umbilical cord blood. Research is underway to develop various sources for stem cells as well as to apply stem-cell treatments for neurodegenerative diseases and conditions such as diabetes and heart disease. Stem-cell therapy has become controversial following developments such as the ability of scientists to isolate and culture embryonic stem cells, to create stem cells using somatic cell nuclear transfer and their use of techniques to create induced pluripotent stem cells. This controversy is often related to abortion politics and to human cloning. Additionally, efforts to market treatments based on transplant of stored umbilical cord blood have been controversial. Medical uses For over 30 year ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osiris Therapeutics
Osiris Therapeutics, Inc. was founded in March 1993 following the identification of mesenchymal stem cells (MSCs) by Dr. Arnold Caplan and colleagues at Case Western Reserve University in Cleveland Ohio. ----Second part of article:Cell research led to Osiris Therapeutics This was years before Geron and Advanced Cell Sciences appeared and garnered massive public attention for their stem cell work. Dr. Caplan contributed a license to the technology and joined Kevin Kimberlin, James S. Burns, a biotech venture capitalist, and Peter Friedli, a "high-tech financier" and lead investor, to launch Osiris; Caplan and Burns had named the company after the Egyptian god of the "lower world". Early financing was provided by a number of entities, including Three Arch Bay Health Sciences Fund of Mountain View, California, Burns and a New York-based acquaintance of Burns. Almost immediately the company tried launching an initial public offering (IPO), but the petition was withdrawn due to low ...

Graft-vs-host Disease
Graft-versus-host disease (GvHD) is a syndrome, characterized by inflammation in different organs. GvHD is commonly associated with bone marrow transplants and stem cell transplants. White blood cells of the donor's immune system which remain within the donated tissue (the graft) recognize the recipient (the host) as foreign (non-self). The white blood cells present within the transplanted tissue then attack the recipient's body's cells, which leads to GvHD. This should not be confused with a transplant rejection, which occurs when the immune system of the transplant recipient rejects the transplanted tissue; GvHD occurs when the donor's immune system's white blood cells reject the recipient. The underlying principle (alloimmunity) is the same, but the details and course may differ. GvHD can also occur after a blood transfusion if the blood products used have not been irradiated or treated with an approved pathogen reduction system. Types In the clinical setting, graft-versus-hos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesoblast
Mesoblast Limited is an Australian-based regenerative medicine company. It seeks to provide treatments for inflammatory ailments, cardiovascular disease and back pain. The company is led by Silviu Itescu, who founded the company in 2004. Mesenchymal lineage cells The company is developing a range of regenerative products derived from its proprietary mesenchymal lineage cells. This includes Mesenchymal Precursor Cells (MPCs) and Mesenchymal Stem Cells (MSCs). It is the hope of Mesoblast that these cells will behave like their natural counterparts, when injected into a patient. Such behavior would require the cells to survive in a patient's body, despite the action of the immune system, which functions to destroy anything that is foreign. Use In the laboratory, highly purified and immunoselected MPCs and the culture expanded MSCs secrete trophic factors that have multiple potential actions. It is hoped that Mesenchymal lineage precursors will retain the ability of their natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cell Therapy
Cell therapy (also called cellular therapy, cell transplantation, or cytotherapy) is a therapy in which viable cells are injected, grafted or implanted into a patient in order to effectuate a medicinal effect, for example, by transplanting T-cells capable of fighting cancer cells via cell-mediated immunity in the course of immunotherapy, or grafting stem cells to regenerate diseased tissues. Cell therapy originated in the nineteenth century when scientists experimented by injecting animal material in an attempt to prevent and treat illness. Although such attempts produced no positive benefit, further research found in the mid twentieth century that human cells could be used to help prevent the human body rejecting transplanted organs, leading in time to successful bone marrow transplantation as has become common practice in treatment for patients that have compromised bone marrow after disease, infection, radiation or chemotherapy. In recent decades, however, stem cell and cel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stem Cell
In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. They are found in both embryonic and adult organisms, but they have slightly different properties in each. They are usually distinguished from progenitor cells, which cannot divide indefinitely, and precursor or blast cells, which are usually committed to differentiating into one cell type. In mammals, roughly 50–150 cells make up the inner cell mass during the blastocyst stage of embryonic development, around days 5–14. These have stem-cell capability. ''In vivo'', they eventually differentiate into all of the body's cell types (making them pluripotent). This process starts with the differentiation into the three germ layers – the ectoderm, mesoderm and endoderm – at the gastrulation stage. However ...

Mesenchymal Stem Cells
Mesenchymal stem cells (MSCs) also known as mesenchymal stromal cells or medicinal signaling cells are multipotent stromal cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells which give rise to marrow adipose tissue). Structure Definition While the terms ''mesenchymal stem cell'' (MSC) and ''marrow stromal cell'' have been used interchangeably for many years, neither term is sufficiently descriptive: * Mesenchyme is embryonic connective tissue that is derived from the mesoderm and that differentiates into hematopoietic and connective tissue, whereas MSCs do not differentiate into hematopoietic cells. * Stromal cells are connective tissue cells that form the supportive structure in which the functional cells of the tissue reside. While this is an accurate description for one function of MSCs, the term fails to convey the relatively recently discovered ...

Acute Respiratory Distress Syndrome
Acute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis). For those who survive, a decreased quality of life is common. Causes may include sepsis, pancreatitis, trauma, pneumonia, and aspiration. The underlying mechanism involves diffuse injury to cells which form the barrier of the microscopic air sacs of the lungs, surfactant dysfunction, activation of the immune system, and dysfunction of the body's regulation of blood clotting. In effect, ARDS impairs the lungs' ability to exchange oxygen and carbon dioxide. Adult diagnosis is based on a PaO2/FiO2 ratio (ratio of partial pressure arterial oxygen and fraction of inspired oxygen) of less than 300 mm Hg despite a positive end-expiratory pressure (PEEP) of more than 5 cm H2O. Cardiogenic pulmonary edema, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
