Pre-Meeting Workshop Will Explore “Cellular Therapies in Trauma and Critical Care”
traumacopy.jpg?r=1538001730622Trauma is a leading cause of death in both military and civilian populations worldwide. Although medical advances have improved the overall morbidity and mortality often associated with trauma, additional research and innovative advancements in therapeutic interventions are still needed to optimize patient outcomes. Cell-based therapies present a novel opportunity to improve trauma and critical care at both the acute and chronic phases that often follow injury. AABB, in collaboration with the Cellular Therapies in Trauma and Critical Care Conference faculty, will present a pre-meeting workshop, “Cellular Therapies in Trauma and Critical Care,” the day before the 2018 AABB Annual Meeting begins in Boston on Oct. 12, from 8:00 am - 5:00 pm. This one-day workshop will focus on the emerging role of CT in treating trauma and critical care conditions. The workshop will also include discussions on aligning the needs of health care providers serving patients receiving critical and trauma care with those running programs and facilities providing the products, and those performing clinical trials and the lessons they learned from designing them. The agenda web page provides topics, scheduled speakers and registration information.

REGULATORY AND GOVERNMENT UPDATE
Revised DHQ for HPC, Apheresis and Marrow and Cord Blood Now Available
The Donor History Questionnaires (DHQs) for the Hematopoietic Progenitor Cell (HPC), Apheresis and Marrow DHQ as well as the Cord Blood DHQ have been updated. The changes revise some FDA guidance document names, dates, and/or website links in the DHQ. A complete summary of the updates in the new version is included in the chart detailing the changes from version 1.8 (apheresis, marrow) and from version 1.5 (cord blood). AABB encourages those with comments or questions to contact regulatory@aabb.org.
NIH, FDA Announce Plans to Streamline Oversight of Human Gene Therapies
stemcellscopy.png?r=1531427143860Officials at the National Institutes of Health (NIH) and United States Food and Drug Administration recently announced plans to streamline oversight of human gene therapies in a New England Journal of Medicine perspective. NIH Director Francis S. Collins, MD, PhD, and FDA Commissioner Scott Gottlieb, MD, propose eliminating duplicative reporting requirements for gene-therapy trials. For example, it would limit the role of NIH and the Recombinant DNA Advisory Committee (RAC) in assessing gene-therapy protocols and reviewing their safety. Additionally, the agency will revise the responsibilities of Institutional Biosafety Committees to align their review of human gene-therapy protocols with other research areas subject to NIH Guidelines.
 
These proposed changes, Collins and Gottlieb note, will allow the RAC to return to its original goal of advising the NIH director on the scientific, safety and ethical issues associated with emerging biotechnology.
FDA Extends Comment Period for Draft Guidance Documents on Development of Human Gene Therapy Products
FDA announced the agency will extend the comment period for the six draft guidance documents about the development of human gene therapy products from the July 12 Federal Register in response to requests for an extension to allow interested individuals additional time to submit comments and any new information. Comments are due by Dec. 10 to the Federal Register.
FDA Warns About Increased Risk of Cancer Relapse With Long-Term Use of Azithromycin After Donor Stem Cell Transplant
The U.S. FDA is warning that the antibiotic azithromycin (Zithromax or Zmax) should not be given long-term to prevent a certain inflammatory lung condition in patients with cancers of the blood or lymph nodes who undergo a donor stem cell transplant. Results of a clinical trial found an increased rate of relapse in cancers affecting the blood and lymph nodes, including death, in these patients. Additional data are being reviewed. Conclusions and recommendations will be communicated when the review has been completed.
 
The serious lung condition for which long-term azithromycin was being studied called bronchiolitis obliterans syndrome is caused by inflammation and scarring in the airways of the lungs, resulting in severe shortness of breath and dry cough. Cancer patients who undergo stem cell transplants from donors are at increased risk for bronchiolitis obliterans syndrome. Pfizer, the manufacturer of brand name azithromycin, is providing a Dear Healthcare Provider letter on this safety issue to health care professionals who care for patients undergoing donor stem cell transplants.

 
RESEARCH FOCUS
Current Practices for Viability Testing of Cryopreserved Cord Blood Products: An International Survey by the Cellular Therapy Team Of The Biomedical Excellence For Safer Transfusion (BEST) Collaborative
survey.jpgViability testing is a common practice in laboratories. The goal of a BEST study by Takenashi et al. was to ascertain current laboratory practices internationally for performing viability testing for cryopreserved cord blood (CB) products and to glean information about how to standardize the method to improve interlaboratory reproducibility. The researchers designed a survey to evaluate current laboratory practices for viability testing and distributed it internationally. The questions covered sampling and testing methods, responses to unexpected results, and the rating of the reliability of the CB quality tests, together with expectations for standardization. Overall, responses indicated that various stains were used among the laboratories, and when multiple sites used the same viability stain, the methods differed. The majority of the respondents favored standardizing the viability testing methods. Flow cytometry with a 7‐AAD dye was suggested as a first step toward standardization.
Effect of Platelet-Rich Plasma on Chondrogenic Differentiation of Adipose- and Bone Marrow-Derived Mesenchymal Stem Cells
Platelet-rich plasma (PRP) is an autologous, growth factor-rich biologic preparation that has received increasing attention as a therapeutic adjunct to treat degenerative joint diseases. There is evidence suggesting that PRP acts by promoting stem cell proliferation and tissue healing. Liou et al. have examined the effect of PRP treatment on chondrogenic differentiation of adult human MSCs derived from infrapatellar fat pad-adipose stem cells (IFP-ASCs) and bone marrow (BM-MSCs). Both cell types were placed in high-density pellet culture and hydrogel-encapsulated culture under chondrogenic conditions. The results showed that PRP did not improve IFP-ASC or BM-MSC chondrogenesis. In general, chondrogenesis was inhibited with increasing PRP concentrations and duration of exposure, based on histological, biochemical and gene expression analyses. Taken together, these findings suggest that although PRP is believed to be beneficial for pain relief and joint function improvement, its mechanism of action is unlikely to directly involve enhancing MSC-mediated hyaline cartilage formation.
Staying ‘Chill’ Even When Disaster Strikes; NIST Cryogenic Teams Working to Protect Valuable Specimens in Biorepositories

Technically, there is no universal definition of a repository, although the International Society for Biological and Environmental Repositories (ISBER) hopes to have one soon. For five years, members of ISBER and other organizations have been developing an ISO standard that would help formalize the term and provide appropriate best practices for running such a facility. The resulting ISBER Best Practices are now freely available online to benefit the entire scientific community. Collaborations among professionals to discuss and develop best practices have been key.
 
The National Institutes of Standards and Technology (NIST) illustrates the importance of a harmonized standard via their description of the rare specimen collection storage at the Hollings Marine Lab located in Charleston, South Carolina.

Human Cell Atlas Aims to Map Every Cell in the Human Body
A project known as the Human Cell Atlas (HCA) Consortium, formed in 2016, is seeking to create an index of every unique type of cell in the body. Researchers hope this catalog will provide new insights into how the body works and how it can ward off disease.
 
The global effort, which currently includes 500 scientists, has received $200 million in funding from the National Institutes of Health. Given the experiences with the National Human Genome Research Institute’s Human Genome Project, researchers acknowledge that cataloging every cell will be time-consuming and may not lead to immediate breakthroughs; however, they are optimistic that the HCA will prove invaluable in disease research.
 
A complimentary white paper available for download provides an overview of the effort. It includes the framework for the first draft of the atlas; descriptions of the technology and data analysis tools available to build the atlas; an introduction to the Data Coordination Platform that will host the data for researchers worldwide; and an in-depth description of the biological systems the Consortium plans to explore and map. The paper also details the organization and governance of the HCA consortium and its relationships with the public — including ethical considerations regarding organ and tissue donors — and to funding support.
