Cell jamming and unjamming in development: physical aspects [PDF]
Collective cell migration is essential for a wide range of biological processes such as: morphogenesis, wound healing, and cancer spreading. However, it is well known that migrating epithelial collectives frequently undergo jamming, stay trapped some period of time, and then start migration again.

TissueMiner: A multiscale analysis toolkit to quantify how cellular processes create tissue dynamics
Segmentation and tracking of cells in long-term time-lapse experiments has emerged as a powerful method to understand how tissue shape changes emerge from the complex choreography of constituent cells.

Research progress in the roles of airway epithelial cells in the pathogenesis of asthma
Asthma is a common chronic respiratory disease, and as a heterogeneous disease, it is driven by a combination of immune, genetic, and environmental factors and involves multiple cells.

Lung Cancer in Pulmonary Fibrosis: Tales of Epithelial Cell Plasticity [PDF]
Lung epithelial cells exhibit a high degree of plasticity. Alterations to lung epithelial cell function are critically involved in several chronic lung diseases such as pulmonary fibrosis.

Epithelial organization and cyst lumen expansion require efficient Sec13-Sec31-driven secretion [PDF]
Epithelial morphogenesis is directed by interactions with the underlying extracellular matrix. Secretion of collagen and other matrix components requires efficient coat complex II (COPII) vesicle formation at the endoplasmic reticulum. Here, we show that

From cells to tissue: A continuum model of epithelial mechanics [PDF]
A continuum model of epithelial tissue mechanics was formulated using cellular-level mechanical ingredients and cell morphogenetic processes, including cellular shape changes and cellular rearrangements. This model can include finite deformation, and incorporates stress and deformation tensors, which can be compared with experimental data.

Emergence of epithelial cell density waves [PDF]
Epithelial cell monolayers exhibit traveling mechanical waves. We rationalize this observation thanks to a hydrodynamic description of the monolayer as a compressible, active and polar material. We show that propagating waves of the cell density, polarity, velocity and stress fields may be due to a Hopf bifurcation occurring above threshold values of ...

Human cytomegalovirus (HCMV) has a broad cellular tropism and epithelial cells are important physiological targets during infection. The retinal pigment epithelial cell line ARPE-19 has been used to model HCMV infection in epithelial cells for decades ...

The effects of growth factors on multicellular spheroids formed by chick embryonic retinal cells [PDF]
Retinal cells from chick embryos aged 7.5 days of gestation were cultured for two months in a non-adherent suspension culture dish to study the effects of growth factors and co-culture with retinal pigment epithelial cells on their differentiation ...

Density fluctuations and border forces direct leader cell plasticity during collective epithelial migrations [PDF]
Epithelial cell monolayers expand on substrates by forming finger-like protrusions, created by leader cells, in the monolayer boundary. Information transmission and communication between individual entities in the cohesive collective lead to long-range order, vortical structures, and disorder to ordered phase transitions. We ask the following questions:
