Healthy cells display an interconnected web of branches with distinct doughnut-shaped loops. Understanding these cellular structures could unlock new pathways for treating nerve damage and tracking recovery processes.
Higher organisms enclose their genetic material within a nuclear envelope consisting of two stacked membranes. To survive, the nucleus must constantly exchange molecules with the cytoplasm through specialized selective channels. These channels, known as nuclear pores, act as vital gates that manage the transport of essential proteins and messenger RNA in and out of the cell's command center.
Researchers at Tampere University have developed a groundbreaking lensless imaging method that captures precise quantitative data on living cells from a single image. The compact system fits inside standard incubators, allowing continuous monitoring for days without the need for toxic stains or fluorescent labels, as published in Applied Physics Letters.
