Latest publication from the Murphy Lab featured on the cover of Blood Advances: De Novo Hematopoiesis from the Fetal Lung!
Hemogenic endothelial cells (HECs) are specialized cells that undergo endothelial-to-hematopoietic transition (EHT) to give rise to the earliest precursors of hematopoietic progenitors that will eventually sustain hematopoiesis throughout the lifetime of an organism. Although HECs are thought to be primarily limited to the aorta-gonad-mesonephros (AGM) during early development, EHT has been described in various other […]
New publication from the Murphy Lab in Science Advances! They led a Team demonstrating that immune cells drive NET tumor progression and susceptibility to therapies
Neuroendocrine tumors (NETs) are rare cancers that most often arise in the gastrointestinal tract and pancreas. The fundamental mechanisms driving gastroenteropancreatic (GEP)–NET growth remain incompletely elucidated; however, the heterogeneous clinical behavior of GEP-NETs suggests that both cellular lineage dynamics and tumor microenvironment influence tumor pathophysiology. Here, we investigated the single-cell transcriptomes of tumor and immune […]
The Mostoslavsky Lab Publishes New Platform to Make T Cells from iPSCs
A robust method of producing mature T cells from iPSCs is needed to realize their therapeutic potential. NOTCH1 is known to be required for the production of hematopoietic progenitor cells with T cell potential in vivo. Here we identify a critical window during mesodermal differentiation when Notch activation robustly improves access to definitive hematopoietic progenitors […]
New Publication for the Murphy Lab, A ‘Blueprint’ for Longevity feature in USA Today, the New York Post and 75 other Media Outlets
Age-related changes in immune cell composition and functionality are associated with multimorbidity and mortality. However, many centenarians delay the onset of aging-related disease suggesting the presence of elite immunity that remains highly functional at extreme old age. To identify immune-specific patterns of aging and extreme human longevity, we analyzed novel single cell profiles from the […]
The latest publication from the Kotton lab detailing the transcriptomic programs of iPSC-derived alveolar cells
Dysfunction of alveolar epithelial type 2 cells (AEC2s), the facultative progenitors of lung alveoli, is implicated in pulmonary disease pathogenesis, highlighting the importance of human in vitro models. However, AEC2-like cells in culture have yet to be directly compared to their in vivo counterparts at single-cell resolution. Here, we performed head-to-head comparisons among the transcriptomes […]
Human iPSC-hepatocyte modeling of Alpha-1-antitrypsin from the Wilson lab is out!
Individuals homozygous for the ‘‘Z’’ mutation in alpha-1 antitrypsin deficiency are known to be at increased risk for liver disease. It has also become clear that some degree of risk is similarly conferred by the heterozygous state. A lack ofmodel systems that recapitulate heterozygosity in human hepatocytes has limited the ability to study the impact […]
A new study by the Hawkins lab showcases an iPSC-airway platform for Cystic Fibrosis
Cystic fibrosis is a monogenic lung disease caused by dysfunction of the cystic fibrosis transmembrane conductance regulator anion channel, resulting in significant morbidity and mortality. The progress in elucidating the role of CFTR using established animal and cellbased models led to the recent discovery of effective modulators for most individuals with CF. However, a subset […]
A new study by the Mostoslavsky/Mühlberger labs describe modeling of Ebola virus infection using iPSC-derived hepatocyte like cells
SUMMARY Liver damage and an exacerbated inflammatory response are hallmarks of Ebola virus (EBOV) infection. Little is known about the intrinsic response to infection in human hepatocytes and their contribution to inflammation. Here, we present an induced pluripotent stem cell (iPSC)-derived hepatocyte-like cell (HLC) platform to define the hepato-intrinsic response to EBOV infection.We used this […]
The Wilson lab new report describing a CRISPR-based platform to study COPD genes in iPSC-alveolar cells
Genome-wide association studies (GWAS) have identified dozens of loci associated with chronic obstructive pulmonary disease (COPD) susceptibility; however, the function of associated genes in the cell type(s) affected in disease remains poorly understood, partly due to a lack of cell models that recapitulate human alveolar biology. Here, we apply CRISPR interference to interrogate the function […]
Comprehensive phenotyping of hematopoietic stem and progenitor cells in the human fetal liver
Hematopoietic stem cells (HSCs) reside at the top of the hematopoietic hierarchy and can give rise to all the mature blood cell types in our body, while at the same time maintaining a pool of HSCs through self-renewing divisions. This potential is reflected in their functional definition as cells that are capable of long-term multi-lineage […]
