Request for Information (RFI): Strategically Critical Resources or Infrastructures Recommended for NHLBI Support Using the R24/U24 Grant Mechanisms

The NHLBI is requesting information on needs for resources or infrastructure to access biospecimens, disease models (cell lines or model organisms), production capabilities, information or data, or standardization of data/tools of relevance to the research mission of the NHLBI. Of particular interest are needs at a national level that could be supported under R24/U24 grant mechanisms.

Publication: “Dye-Independent Methods Reveal Elevated Mitochondrial Mass in Hematopoietic Stem Cells”

Drs. Hans-Willem Snoeck, Mariana Justino de Almeida, Larry Luchsinger, and colleagues correct the erroneous impression that HSCs have low mitochondrial content. HSCs exhibit high mitochondrial content yet possess limited respiratory and turnover capacity. [07Dec2017 Cell Stem Cell]

Training Opportunity: “Human Induced Pluripotent Stem Cells and Their Differentiation into Endoderm and Lung-Progeny” at Boston Medical Center (April 9-13, 2018)

The Center for Regenerative Medicine (CReM) at Boston University Medical Center is offering a five-day course that will focus on deriving, maintaining, characterizing and differentiating human induced pluripotent stem cells (hiPSCs). Small class size will enable researchers to learn the entire process of reprogramming from somatic cell preparation, to reprogramming methodologies, iPSC identification, isolation and characterization, and current approaches to their directed differentiation into endodermal and lung lineages.

“Distinct Mesenchymal Lineages and Niches Promote Epithelial Self-Renewal and Myofibrogenesis in the Lung”

Drs. Edward Morrisey, Jarod Zepp, William Zacharias, and colleagues report on the functional pathways that define the cellular and molecular framework of lung mesenchymal niches and reveal the functional importance of developmental pathways in promoting self-renewal versus a pathological response to tissue injury.

“Cardiopatch Platform Enables Maturation and Scale-up of Human Pluripotent Stem Cell-derived Engineered Heart Tissues”

Drs. Nenad Bursac, Ilya Shadrin, Brian Allen, and colleagues report on a “Cardiopatch” platform for 3D culture and maturation of hiPSC-CMs (after 5 weeks of differentiation) showing robust electromechanical coupling, consistent H-zones, I-bands, and evidence for T-tubules and M-bands.
