Organovo unveils bioprinted liver transplant patches

Organovo (PINK:ONVO) today announced it is developing 3D bioprinted human liver tissue designed for direct transplantation to patients. The move to human development comes based on “strong results” from preclinical animal model studies, the San Diego, Calif.-based company said. The company expects to pursue a formal preclinical development program. “We’re excited to introduce an implantable bioprinted liver tissue as the first preclinical candidate in our therapeutic tissue portfolio, and see the early results as extremely promising. The scientific and commercial progress we have already made with ExVive Human Liver Tissue in drug toxicity testing has given us a firm foundation upon which to build a larger tissue for transplant.  Advancing our first therapeutic tissue into preclinical development is an important milestone for Organovo, and it speaks to the power of our technology platform in addressing multiple applications, including preclinical safety, disease modeling and tissue replacement products for surgical implantation.  We believe that 3D bioprinted tissues have an opportunity to provide options for patients who suffer from liver disorders,” CEO Keith Murphy said in a press release. Organovo said it plans to submit an investigational new drug application to the FDA within 3 to 5 years for the new tissue, as well as pursuing a breakthrough therapy designation to accelerate time to market. “Organovo&rsq...

Abstract SRTR is considering more prominent reporting of program‐specific adjusted transplant rate ratios (TRRs). To enable more useful reporting of TRRs, SRTR updated the transplant rate models to explicitly adjust for components of allocation priority. We evaluated potential associations between TRRs and components of allocation priority that could indicate programs’ ability to manipulate TRRs by denying or delaying access to low‐priority candidates. Despite a strong association with unadjusted TRRs, we found no candidate‐level association between the components of allocation priority and adjusted TRRs. We fo...

By ANISH KOKA, MD No one knows who Bennie Solis is anymore. He had the misfortune of being born in the early 1960s marked for death. He had a rare peculiar condition called biliary atresia – a disease defined by the absence of a conduit for bile to travel from his liver to his intestinal tract. Bile acid produced in the liver normally travels to the intestines much like water from a spring travels via ever larger channels to eventually empty into the ocean. Bile produced in the liver with no where to go dams up in the liver and starts to destroy it. That the liver is a hardy organ was a fact known to the ancient Gree...

Discussion of advocacy for the cause is a usual feature of our community, as we try things and attempt to make progress in persuading the world that rejuvenation research is plausible, practical, and necessary. There are more people engaged in advocacy now than at any time in the past decade, and so discussions of strategy come up often. New ventures kicked off in 2017 include the Geroscience online magazine, and among the existing ventures the LEAF / Lifespan.io volunteers seem to be hitting their stride. The mainstream media continues to be as much a hindrance as a help, and where it is a help you will usually find Aubre...

AbstractPurposeEnd-stage renal disease (ESRD) is associated with increased cardiovascular risk factors, electrolyte imbalances, and iron deficiency anemia. These factors may increase the risk of adverse outcomes in patients undergoing panniculectomy. There is a paucity of data regarding outcomes in patients with ESRD undergoing panniculectomy. The purpose of this study is to investigate whether ESRD is associated with increased rate of complications following a panniculectomy.MethodThe Nationwide Inpatient Sample database (2006 –2011) was used to identify patients who underwent a panniculectomy. Among this cohort, pa...

In this study, we have shown that the lipid chaperones FABP4/FABP5 are critical intermediate factors in the deterioration of metabolic systems during aging. Consistent with their roles in chronic inflammation and insulin resistance in young prediabetic mice, we found that FABPs promote the deterioration of glucose homeostasis; metabolic tissue pathologies, particularly in white and brown adipose tissue and liver; and local and systemic inflammation associated with aging. A systematic approach, including lipidomics and pathway-focused transcript analysis, revealed that calorie restriction (CR) and Fabp4/5 deficiency result ...

Morbid obesity has been shown to increase risk of perioperative complications, delayed graft function, and mortality in kidney, liver, and lung/heart transplants. Both laparoscopic gastric bypass(LGBP) and laparoscopic sleeve gastrectomy(LSG) have been proven to be safe and efficacious in patients with end-stage kidney and liver disease of various etiologies, and are utilized to improve transplant candidacy by treating morbid obesity and associated co-morbidities, however the optimal bariatric operation for each transplant is not clear.

AbstractIntraoperative transesophageal echocardiography is a minimally invasive monitoring tool that can provide real-time visual information on ventricular function and hemodynamic volume status in patients undergoing liver transplantation. The American Association for the Study of Liver Diseases states that transesophageal echocardiography should be used in all liver transplant candidates in order to assess chamber sizes, hypertrophy, systolic and diastolic function, valvular function, and left ventricle outflow tract obstruction. However, intraoperative transesophageal echocardiography can be used to “visualize&rd...

In this study, we focused on two pathways of cardiomyocytes or heart cells: the Hippo pathway, which is involved in stopping renewal of adult cardiomyocytes, and the dystrophin glycoprotein complex (DGC) pathway, essential for cardiomyocyte normal functions." Previous work had hinted that components of the DGC pathway may somehow interact with members of the Hippo pathway. The researchers genetically engineered mice to lack genes involved in one or both pathways, and then determined the ability of the heart to repair an injury. These studies showed for the first time that dystroglycan 1, a component of the DGC ...
