Researchers create accurate model of organ scarring using stem cells in a lab

Every organ in the body is capable, to some extent, of repairing itself after an injury. As part of this process, scar tissue forms and then recedes to make room for normal tissue when healing is complete.However, when healing is disrupted — whether by chronic injury or disease — the cells that make up scar tissue can go rogue, continuously dividing and spreading until the scar eventually strangles the organ it was intended to help heal, which can lead to organ failure.That progressive, out-of-control scarring is called fibrosis, and it can occur in any organ in the body. Fibrosis plays a major role in many diseases and conditions, including chronic kidney disease, liver cirrhosis, idiopathic pulmonary fibrosis, scleroderma and heart failure.“Millions of people living with fibrosis have very limited treatment options,” said Dr. Brigitte Gomperts, a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA. “Once scarring gets out of control, we don’t have any treatments that can stop it, except for whole-organ transplant.”For decades, researchers have been seeking a therapy that can halt or reverse fibrosis, but one major roadblock has been the difficulty of replicating the complex, progressive nature of the disease in the lab, where possible treatments could be tested.Now, a team led by Gomperts has developed a “scar in a dish” model that uses multiple types of cells derived fr...

Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...

Authors: Matti B, Zargar-Shoshtari K Abstract Prostate cancer represents a significant health burden worldwide. The cancer incidence had substantially increased since the introduction of prostate specific antigen (PSA) in cancer screening. This had led to considerable debates among health professionals and epidemiologists, since PSA as a screening tool seemed to be far from perfect. In New Zealand, the controversy was quite prominent in the last three decades, with some advocating the benefits of screening, while others concerned regarding the risk of harms. With the absence of an organised screening programme and ...

CONCLUSION: This study found that childhood cancer survivors in New Zealand had a high prevalence of developmental dental abnormalities and it identified potential risk factors related to their cancer treatment. Inequitable access to oral rehabilitation for this patient group argues for a mechanism for consistent improved access to publicly funded dental care across district health boards in New Zealand.
