TOP STORYTumor Cell Biodiversity Drives Microenvironmental Reprogramming in Liver Cancer Researchers found varying degrees of heterogeneity in malignant cells within and between tumors and diverse landscapes of tumor microenvironment. Strikingly, tumors with higher transcriptomic diversity were associated with patients’ worse overall survival. [Cancer Cell] Full Article | Graphical Abstract | Press Release | |

PUBLICATIONS(Ranked by impact factor of the journal)Scientists presented a tunable 3D bioengineered brain tissue platform by integrating microenvironmental cues of native brain-derived ECMs and live imaging to systematically evaluate patient-derived brain tumor responses. [Nat Commun] Full Article | Press Release Investigators demonstrated that fibrotic signaling altered gating of the mitochondrial calcium uniporter in a MICU1-dependent fashion to reduce mCa2+ uptake and induce coordinated changes in metabolism. [Nat Commun] Full Article Bmi1 Drives Hepatocarcinogenesis by Repressing the TGFβ2/SMAD Signaling Axis The authors report that TGFβ2 was a target of Bmi1 in HCC and had a tumor-suppressing role. In Bmi1-knockout mouse livers and hepatocellular carcinoma cell lines, TGFβ2/SMAD cascade proteins were upregulated. [Oncogene] Abstract Researchers report that pretreatment with an intermittent compressive force, but not a continuous compressive force, promoted human peridontal ligament cell osteogenic differentiation as determined by osteogenic marker gene expression and mineral deposition in vitro. [Cell Death Dis] Full Article Galectin-3 (Gal-3) controlled intercellular and cell-extracellular matrix interactions during immunological responses. Scientists used pristane to induce lupus-like syndrome in Gal-3 deficient (Lgals3-/-) and Lgals3+/+ BALB/c mice. [Sci Rep] Full Article Investigators set up a new aligned polyacrylonitrile-derived nanofiber scaffold. This system was suitable for drug screening as well as discrimination of the migration potential of different glioblastoma stem cells. [Sci Rep] Full Article The authors investigated the response of T. cruzi-infected cardiomyocytes (CM), cardiac fibroblasts (CF), and L6E9 skeletal myoblasts to transforming growth factor beta (TGF-β). Cultures of CM, CF, and L6E9 were infected with T. cruzi and treated with TGF-β. [Int J Mol Sci] Full Article When mesenchymal stem cells were seeded in solid collagen scaffolds, they differentiated into myofibroblasts that were observed to strongly bind to the substrate, forming a 3D cell scaffold network that developed tension and shortening after KCl stimulation.

INDUSTRY NEWSHHS Awards Major Funding Award to WFIRM The Wake Forest Institute for Regenerative Medicine (WFIRM) is the recipient of a major research funding award from the US Department of Health and Human Services (HHS) to support its lung-on-a-chip technology as a model to develop chemical injury treatments. [Wake Forest Baptist Medical Center] Press Release Biogelx Commences International Strategy Launching 3D Bioprinting Material in Brazil Biogelx has launched an international distribution strategy for its 3D printable inks. Working with 3D Biotechnology Solutions, the company has set its sights on the Brazilian medical sector. [Biogelx (3D Printing Industry)] Press Release | |

POLICY NEWSNIH Marquee Awards for ‘High Risk, High Reward’ Projects Skew Male—Again For three of the four types of “high risk, high reward” awards, women won in numbers that met or exceeded their representation in the applicant pool. However, that representation was meager: 18% percent to 38% of the applicants for these four awards were women, although women have earned more than 50% of US PhDs in biological sciences in every year since 2008. [ScienceMagazine] Editorial Biologists Who Decoded How Cells Sense Oxygen Win Medicine Nobel A trio of researchers has won the 2019 Nobel Prize in Physiology or Medicine for describing how cells sense and respond to changing oxygen levels by switching genes on and off — a discovery that has been key in understanding human diseases such as cancer and anemia.
