MRI scans were performed before and after the initiation of treatment for Alzheimer's disease patients, and the DTI-ALPS ...

Actin-based vesicular trafficking of Cdc42, leading to a polarized concentration of the GTPase, has been implicated in cell polarization, but it was recently debated whether this mechanism allows ...

Red blood cells (RBCs) are a type of blood cell whose role is to transport oxygen from the lungs to the peripheral tissues of the body. Oxygen diffuses from the alveoli of the lungs into the RBCs, ...

Sticky spots on cell membranes hold onto the master regulator of cell polarity, helping to ensure that the regulatory protein accumulates in high enough concentrations to trigger cell polarity. Over ...

New work describes vital aspects of diffusion processes in tissue development, including the roles that molecular diffusion gradients have on stem cell signaling pathways along with new modeling tools ...

The film explores the evolution of multi-celled animals, particularly sponges, from single-celled organisms like amoebas. It explains that the transition to multi-cellularity was driven by the ...

Copley Scientific’s new Vertical Diffusion Cell Test System Model HDT 1000 comprises a compact unit with 10 test stations that enables the precise control of test conditions. Copley Scientific’s new ...
