Neutrophils promote laser-induced choroidal neovascularization by increasing pro-inflammatory cytokines secretion and cell cycle arrest in retinal pigment epithelium.

Inflammation is hypothesized to have essential functions in the development of wet age-related macular degeneration (AMD). Polymorphonuclear neutrophils (PMNs), recognized as major players in inflammation, are typically the first leukocytes to be recruited to an inflammatory site. Previous studies have identified neutrophil aggregates in the lesion site of the choroidal neovascularization model, and systemic depletion of neutrophils in adult mice is associated with reduced choroidal neovascularization (CNV) area, suggesting a pivotal role of PMNs in CNV pathogenesis.

Elongation of the nascent avian foregut requires coordination of intrinsic and extrinsic cell behaviors.

The foregut tube gives rise to the lungs and upper gastrointestinal tract, enabling vital functions of respiration and digestion. How the foregut tube forms during embryonic development has historically received considerable attention, but over the past few decades this question has primarily been addressed indirectly through studies on morphogenesis of the primitive heart tube, a closely related process. As a result, many aspects of foregut development remain unresolved.
