Scientists image molecules vital for gene regulation

All the trillions of cells in our body share the same genetic information and are derived from a single, fertilized egg. When this initial cell multiplies during fetal development, its daughter cells become more and more ...

Dissecting the brain's primary developmental engine

(Phys.org) —Last month, researchers reported the creation of the first primitive brain-like structures made from human stem cells. To create the complex morphology of these cerebral organoids, cells within a proliferating ...

Protein lifetime and the stability of cell structures

(Phys.org) —The ability of a cell to move, replicate, and recast itself according to the needs of the organism which it serves, comes at it price. The extreme flexibility of cells takes its origin from the constant turnover ...

Packaging process for genes discovered

Scientists at Penn State University have achieved a major milestone in the attempt to assemble, in a test tube, entire chromosomes from their component parts. The achievement reveals the process a cell uses to package the ...

How epigenetic switches control gene expression

Scientists at Tokyo Institute of Technology have deciphered how to quantitatively assess the effects of specific epigenetic changes on the rate of transcription by developing a mathematical model. Using their method, they ...
