Niche-independent symmetrical self-renewal of a mammalian tissue stem cell. [PDF]

, 2005
Pluripotent mouse embryonic stem (ES) cells multiply in simple monoculture by symmetrical divisions. In vivo, however, stem cells are generally thought to depend on specialised cellular microenvironments and to undergo predominantly asymmetric divisions.

A cocktail hydrogel promoting the functional interneurons regeneration of human neural progenitor cells for brain injury therapy

Journal of Advanced Research
Introduction: Traumatic Brain Injury (TBI) usually leads to substantial mortality and disability among adult populations. Neural progenitor cells (NPCs) transplantation exhibits great potential in TBI treatment.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Neuroblast lineage identification and Hox gene action during postembryonic development of the tritocerebrum and subesophageal ganglion in the "Drosophila" brain [PDF]

, 2013
In this thesis, the neuroblast lineages which give rise to the adult-specific interneurons of two Drosophila brain regions, the tritocerebrum and the subesophageal ganglion, were described, and an analysis of the expression and function of the ...

Ductal Ngn3-expressing progenitors contribute to adult β cell neogenesis in the pancreas

, 2021
Ductal cells have been proposed as a source of adult β cell neogenesis, but this has remained controversial. By combining lineage tracing, 3D imaging, and single-cell RNA sequencing (scRNA-seq) approaches, we show that ductal cells contribute to the β ...

Cell type composition and circuit organization of clonally related excitatory neurons in the juvenile mouse neocortex

eLife, 2020
Clones of excitatory neurons derived from a common progenitor have been proposed to serve as elementary information processing modules in the neocortex.

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

The transcriptional activator Gli2 modulates T-cell receptor signalling through attenuation of AP-1 and NFκ-B activity. [PDF]

, 2015
Different tissues contain diverse and dynamic cellular niches, providing distinct signals to tissue-resident or migratory, infiltrating immune cells.

Single-cell analysis reveals T cell dysfunction driven by macrophages and differential expression of transposable elements in severe COVID-19 patients

Heliyon
The vastly spreading COVID-19 pneumonia is caused by SARS-CoV-2. Lymphopenia and cytokine levels are tightly associated with disease severity. However, virus-induced immune dysregulation at cellular and molecular levels remains largely undefined.

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created
