Membrane around tumors may be key to preventing metastasis

For cancer cells to metastasize, they must first break free of a tumor's own defenses. Most tumors are sheathed in a protective "basement" membrane—a thin, pliable film that holds cancer cells in place as they grow and ...

Artificial organs now produced more easily

A Korean research group has developed a technology that allows for the differentiation of stem cells into desired cell types, such as vascular mural cells or osteoblasts, without special pretreatment. This technology is expected ...

Cell membrane

The cell membrane (also called the plasma membrane or plasmalemma) is the biological membrane separating the interior of a cell from the outside environment.

It is a semipermeable lipid bilayer found in all cells. It contains a wide variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes such as cell adhesion, ion channel conductance and cell signaling. The plasma membrane also serves as the attachment point for both the intracellular cytoskeleton and, if present, the extracellular cell wall.
