New technique ‘prints’ cells to create diverse biological environments

April 4, 2020 dna 0
With the help of photolithography and programmable DNA, researchers have created a new technique that can rapidly ‘print’ two-dimensional arrays of cells and proteins that mimic a wide variety of cellular environments in the body. This technique could help scientists develop a better understanding of the complex cell-to-cell messaging that dictates a cell’s final fate.

Discovery of new biomarker in blood could lead to early test for Alzheimer’s disease

April 4, 2020 dna 0
Researchers discovered that high blood levels of RNA produced by the PHGDH gene could serve as a biomarker for early detection of Alzheimer’s disease. The work could lead to the development of a blood test to identify individuals who will develop the disease years before they show symptoms.

Reconstructing the clock of human development

April 4, 2020 dna 0
Researchers used iPS cells to reconstructed the human ‘segmentation clock,’ a key point in early embryonic development that determines how the body gets segmented. The ‘segmentation clock’ is a genetic oscillator that controls and guides the emergence of ‘somites,’ distinct collections of cells that contribute to the formation of the vertebrae and ribs. Segmentation clock genes a have been studied extensively in many animals, except humans.
