The researchers explained that the stiff, straight, long chains of saturated fatty acids rigidify the lipid molecules and cause them to separate from the rest of the cell's membrane.

Images taken with an electron microscope confirmed that not only was its DNA separate from the rest of the cell, it was enclosed by a double membrane — just like the membrane envelope surrounding the nucleus of complex cells.

In an effort to overcome these limitations, a team at the Wyss Institute for Biologically Inspired Engineering led by its Founding Director, Donald Ingber, M.D., Ph.D., had previously engineered a microfluidic «Organ - on - a-Chip» (Organ Chip) culture device in which cells from a human intestinal cell line originally isolated from a tumor were cultured in one of two parallel running channels, separated by a porous matrix - coated membrane from human blood vessel - derived endothelial cells in the adjacent channel.

The team constructed a custom - built flow cell in which two channels were separated by an anion - exchange membrane.

Previous work has given insights into the mechanistic pathways leading to small molecule sequestration in membrane - free coacervate protocells; successfully demonstrated the use of liquid - liquid phase separated micro compartments for protein expression using cell free expression systems; exploited microfluidics for the high throughput formation of stable, monodisperse microdroplets; and integrated two contrasting modes of protocell construction to produce a novel hybrid model based on fatty acid membrane - bound coacervate micro-droplets.

«A whole generation of cancer investigators, including me, has been taught that PTEN performs its crucial role at the plasma membrane, which is what separates the inside of cells from the outside environment» Trotman explains.

Basement membrane (BM) is a dense sheet of specialised extracellular matrix that separates epithelial layers of cells from the underlying tissue.

Key to each of these units is a structure known the «glomerulus», in which podocyte cells wrap themselves tightly around a tuft of capillaries separated only by a thin membrane composed of extracellular matrix, and leave slits between them to build an actual filtration barrier.

«Our method not only uses soluble factors that guide kidney development in the embryo but, by growing and differentiating stem cells on extracellular matrix components that are also contained in the membrane separating the glomerular blood and urinary systems, we more closely mimic the natural environment in which podocytes are induced and mature,» said Musah.

The researchers then devised an assay that deployed native basement membrane to separate cancer cells on one side and fibroblasts embedded in collagen on the other.
