Wounded epidermal keratinocytes emit a signal that activates a specialized T-cell in the skin, leading to an increase in hair follicle stem cell numbers that contributes to tissue repair.
SAA removes toxic products of lipolysis of the cell membrane by sPLA2, indicating that SAA and sPLA2 act synergistically to clear debris from injured sites, as required for tissue healing.
The monitoring of ATP dynamics in living plants using fluorescent protein biosensor provides evidence for the complex relationship between cellular energy status and growth.
Chick optic fissure closure is a powerful new model system for epithelial fusion and has revealed Netrin-1 as a conserved and essential mediator of tissue fusion in multiple contexts.
Immunolabelling and morphological assessment, complemented by complete transcriptomic analysis, demonstrates that supporting cells can be induced to convert towards a hair cell-like phenotype in human vestibular sensory epithelia.
Infection and metabolic syndrome lead to a loss of molecular regulation, and changes in molecular correlations are under genetic control as revealed by the presence of correlation quantitative trait loci.
RNA sequencing reveals the finer details of circadian variation in the mammalian master pacemaker over 24 hours, which suggests that transcriptional timing influences clock resetting mechanisms.
A multiphase hydrodynamic theory reveals that the dynamics of colony expansion in microbial swarms and biofilms are limited by the constraints of water and nutrient availability.
