A new chapter by renowned applied stem cell therapy expert, Neil Riordan, PhD of the Riordan-McKenna Institute in Southlake, Texas; Medistem Labs Panama, and the Stem Cell Institute in Panama City, Panama, entitled, “Cell Therapy for Liver Failure: A New Horizon” is now available in the printed and online medical reference, “Contemporary Liver Transplantation – The Successful Liver Transplant Program”. Contemporary Liver Transplantation provides a comprehensive review of the most crucial and provocative aspects of liver transplantation. The reference covers all disciplines involved in a multidisciplinary liver transplant team; provides a valuable resource for surgeons, hepatologists, anesthesiologists, transplant coordinators and administrators, amongst others; addresses organizational issues that are vital to the good performance of transplant programs; and offers the first 360-degree analysis of liver transplantation. Liver failure is the seventh largest cause of death in industrialized countries. It occurs as a result of a number of acute and chronic clinical inciting factors, including drug-/alcohol-induced hepatotoxicity, viral infections, vascular injury, autoimmune disease, or genetic predisposition. The only available cure, liver transplantation, is severely limited by a lack of donors and further complicated by the adverse effects of chronic immune suppression. In his chapter on stem cell therapy for liver failure, Dr. Riordan examines pre-clinical data and analyzes published clinical trials to identify promising sources of autologous stem cells to treat liver failure including: bone marrow mesenchymal stem cells (BM-MSC), adipose tissue MSC (AT-MSC), and bone marrow mononuclear cells (BMMC) including their purified forms. In addition, he delves into allogeneic stem cells such as those harvested from umbilical cords after normal, healthy births. “Many liver failure patients contact our clinics in Panama and Texas asking if there is anything we can do for them. Unfortunately, we have to tell them that we cannot treat liver failure. Even though some clinical trials have shown signals of efficacy, which is encouraging, I don’t think sufficient rationale exists to treat liver failure patients with the types of stem cells I’ve studied at present,” stated Dr. Riordan. RMI specializes in non-surgical treatment of acute and chronic orthopedic conditions using *amniotic tissue allograft and bone marrow aspirate concentrate (BMAC) that is harvested using the patented BioMAC bone marrow aspiration cannula. Common conditions treated include meniscal tears, ACL injuries, rotator cuff injuries, runner’s knee, tennis elbow, and joint pain due to degenerative conditions like osteoarthritis. Additionally, RMI augments orthopedic surgeries with BMAC and amniotic tissue allograft to promote better post-surgical outcomes and uses amniotic membranes as part of a complete wound care treatment regimen. BMAC contains a patient’s own mesenchymal stem cells (MSC,) hematopoietic stem cells (CD34+), growth factors and other progenitor cells. Amniotic tissue allograft is composed of collagens and other structural proteins, which provide a biologic matrix that supports angiogenesis, tissue growth and new collagen during tissue regeneration and repair. Founded in 2007 on the principles of providing unbiased, scientifically sound treatment options; the Stem Cell Institute (SCI) has matured into the world’s leading adult stem cell therapy and research center. In close collaboration with universities and physicians world-wide, our comprehensive stem cell treatment protocols employ well-targeted combinations of autologous bone marrow stem cells, autologous adipose stem cells, and donor *human umbilical cord stem cells to treat: autism, cerebral palsy, multiple sclerosis, spinal cord injury, osteoarthritis, rheumatoid arthritis, heart disease, and autoimmune diseases. In partnership with Translational Biosciences, a subsidiary of Medistem Panama, SCI provides clinical services for ongoing clinical trials that are assessing safety and signs of efficacy for autism, multiple sclerosis, osteoarthritis, rheumatoid arthritis, and spinal cord injury using allogeneic umbilical cord tissue-derived mesenchymal stem cells (hUC-MSC) and hU-MSC-derived mesenchymal trophic factors (MTF). In 2017, Translation Biosciences plans to expand its clinical trial portfolio to include heart disease and cerebral palsy. For more information on stem cell therapy: Since opening its doors in 2007, Medistem Panama Inc. has developed adult stem cell-based products from human umbilical cord tissue and blood, adipose (fat) tissue and bone marrow. Medistem operates an 8000 sq. ft. ISO 9001-certified laboratory in the prestigious City of Knowledge. The laboratory is fully licensed by the Panamanian Ministry of Health and features 3 class 10000 clean rooms, class 100 laminar flow hoods, and class 100 incubators. Edited by Cataldo Doria, Contemporary Liver Transplantation provides a comprehensive review of the most crucial and provocative aspects of liver transplantation. It represents a unique source of information and guidance for the current generation of transplant surgeons that evolved from being pure clinicians into savvy administrators knowledgeable in every regulatory aspect governing transplantation. The book contains 35 chapters covering every single aspect of the surgical operation in the donors as well as the recipients of liver transplants. The pre-operative work-up, as well as the post-operative immunosuppression management and the treatment of recurrent diseases are addressed in detail. Single chapters are dedicated to controversial issues like transplantation in patients diagnosed with NASH, transplantation for patients diagnosed with HCC beyond Milan criteria and usage of HIV positive donors. Dedicated chapters on HCV, HCC, FHF and NASH will make this book a unique resource for any health care provider part of the multidisciplinary liver transplant team. The book goes beyond the analysis of the formal medical and surgical aspects of liver transplantation and introduces deep knowledge on key aspects of contemporary transplant programs, such as: physical rehabilitation, palliative care, pregnancy, the multiple requirements of regulatory agencies ruling transplantation, quality measurements for transplant programs, finance and liability. The book is organized in 9 sections focusing on each key aspect of liver transplantation. Contemporary Liver Transplantation addresses the need and the questions of the multidisciplinary group involved including surgeons, Hepatologists, anesthesiologists, infectious disease specialists, radiologists, transplant coordinators, financial specialists, epidemiologists and administrators.

Background: The rapid clinical translation of mesenchymal stem cells (MSC) has resulted in the development of cell-based strategies for multiple indications. Unfortunately one major barrier to widespread implementation of MSC-based therapies is the limited supply of fetal calf serum (FCS) used to expand cells to therapeutic numbers. Additionally, the xenogeneic element of fetal calf serum has been previously demonstrated to stimulate antibody mediated reactions and in some cases sensitization leading to anaphylaxis. Method: XcytePLUS™ media, a human platelet lysate based product, was used to supplement the culture medium at 5, 7.5 and 10% and compared to fetal calf serum at 10%, for human umbilical cord MSC expansion. Properties of the expanded cells were investigated. Results: This study demonstrated equivalent or superior effects of human platelet lysate compared to standard FCS supplemented media, based on doubling rate, without loss of identity or function, as demonstrated with flow cytometry characterization. Differentiation into osteocytes, adipocytes and chondrocytes was comparable from cells expanded in either media supplement. Conclusions: These data support the implementation of human platelet lysate supplemented media as an alternative to xenogeneic containing preparations which may lead to safer MSC products with therapeutic uses. © 2015 Riordan et al.

The mesenchymal stem cell (MSC) is being broadly studied in clinical trials. Contrary to the early paradigm of cell replacement and differentiation as a therapeutic mechanism of action, evidence is mounting that the secretions of the cells are responsible for their therapeutic effects. These secretions include molecules and extracellular vesicles that have both local and distant effects. This review summarizes the up- and down-regulation of MSC anti-inflammatory, immune modulating, anti-tumor, and regenerative secretions resulting from different stimuli including: a) hypoxia, which increases the production of growth factors and anti-inflammatory molecules; b) pro-inflammatory stimuli that induce the secretion of immune modulating and anti-inflammatory factors; and c) 3 dimensional growth which up regulates the production of anti-cancer factors and anti-inflammatory molecules compared to monolayer culture. Finally we review in detail the most important factors present in conditioned medium of MSC that can be considered protagonists of MSC physiological effects including HGF, TGF-b, VEGF, TSG-6, PGE2 and galectins 1, and 9. We conclude that there is potential for the development of acellular therapeutic interventions for autoimmune, inflammatory, and malignant diseases and tissue regeneration from cellular secretions derived from MSCs cultured under the appropriate conditions. © 2014 Madrigal et al.

Introduction: Non-healing wounds can pose a medical challenge as in the case of vasculopathic venostasis resulting in a surgical ulcer. When traditional approaches to wound care fail, an amniotic patch (a dehydrated tissue allograft derived from human amnion) can function as a biologic scaffold to facilitate and enhance tissue regeneration and rehabilitation. Background: Amniotic AlphaPatches contain concentrated molecules of PGE2, WNT4, and GDF-11 which have angiogenic, trophic, and anti-inflammatory effects on tissues that may be useful in enhancing wound healing. Aim-case report: We present a case of a severe non-healing surgical wound in a 78-year-old male 17 days post right total knee arthroplasty. The full-thickness wound exhibited a mobile flap, measured 4 cm long × 3 cm wide, and showed undermining down to patellar tissue. We treated the wound conservatively for 6 weeks with no evidence of wound healing. Upon failure of the conservative treatment, two amniotic AlphaPatch (Amniotic Therapies, Dallas, TX, USA) were applied to the wound, and the wound healed completely in 10 weeks. Methods: In the OR, the wound was irrigated with three liters of double antibiotic solution under pulse lavage. Two dry amniotic AlphaPatch (4 cm × 4 cm) were placed over the wound with Acticoat applied on top. Results: At the two-week follow-up visit (following the incision and drainage of the wound dehiscence and application of the amniotic AlphaPatch), a central scab had formed centrally in the wound dehiscence area. At the four-week follow-up visit, the wound dehiscence area had completely scabbed over with no open areas left. At the eight-week follow-up visit, the scab had just fallen off, and the wound was healing well with immature skin representing the size of a penny. At the ten-week follow-up visit, the wound was completely healed. Discussion/conclusion: Sterile, dehydrated amniotic tissue AlphaPatches (containing trophic factors known to enhance wound healing) have proven effective in completely healing an otherwise non-healing wound in a 78-year-old male who failed six weeks of conservative wound care treatment. © 2015 Riordan et al.
