Researchers find a way to delay aging of stem cells
Stem cells are essential building blocks for all organisms, from plants to humans. They can divide and renew themselves throughout life, differentiating into the specialized tissues needed during development, ...

Crowding causes cells to produce an orderly matrix of molecules
When researchers conduct experiments on the way cells grow and respond to outside cues, they tend to use solutions that are much more dilute than the crowded environments found inside living cells. Now, new ...

Mechanical properties of stem cells can foretell what they will become
To become better healers, tissue engineering need a timely and reliable way to obtain enough raw materials: cells that either already are or can become the tissue they need to build. In a new study, Brown ...

Central nervous system stem cells shed light on mechanism that controls asymmetrical division
Animals consist of many distinct cell types, all of which originate during development from a single cell: the fertilized egg. To generate this vast cellular diversity, the egg and its descendants must divide ...

New technique reveals unseen information in DNA code
Imagine reading an entire book, but then realizing that your glasses did not allow you to distinguish "g" from "q." What details did you miss? Geneticists faced a similar problem with the recent discovery ...

Genetic packing: Successful stem cell differentiation requires DNA compaction, study finds
(Phys.org) -- New research findings show that embryonic stem cells unable to fully compact the DNA inside them cannot complete their primary task: differentiation into specific cell types that give rise to ...

Stem cells poised to self-destruct for the good of the embryo
Embryonic stem cells — those revered cells that give rise to every cell type in the body — just got another badge of honor. If they suffer damage that makes them a threat to the developing embryo, ...

Jarid2 may break the Polycomb silence
Historically, fly and human Polycomb proteins were considered textbook exemplars of transcriptional repressors, or proteins that silence the process by which DNA gives rise to new proteins. Now, work by a ...
