New jigsaw piece for the repair of DNA crosslinks

Environmental influences such as ionizing radiation, intense heat or various chemical substances damage the DNA constantly. Only thanks to efficient repair systems can mutations – changes in the DNA – largely be prevented. ...

Bone marrow-on-a-chip unveiled

The latest organ-on-a-chip from Harvard's Wyss Institute for Biologically Inspired Engineering reproduces the structure, functions and cellular make-up of bone marrow, a complex tissue that until now could only be studied ...

Fighting cancer with lasers and nanoballoons that pop

Chemotherapeutic drugs excel at fighting cancer, but they're not so efficient at getting where they need to go. They often interact with blood, bone marrow and other healthy bodily systems. This dilutes the drugs and causes ...

Immune cells regulate blood stem cells

Researchers in Bern, Germany, have discovered that, during a viral infection, immune cells control the blood stem cells in the bone marrow and therefore also the body's own defences. The findings could allow for new forms ...

Researchers gain fuller picture of cell protein reactions

Over the past decade, advances in genetic mapping tools have provided great insight into how DNA influences cell behavior. But genetics is only half the equation; much of cells' behavior is the result of post-transcriptional ...

A bio patch that can regrow bone

Researchers at the University of Iowa have created a bio patch to regenerate missing or damaged bone by putting DNA into a nano-sized particle that delivers bone-producing instructions directly into cells.

Targeting cancer's 'queen bees' with better tissue modeling

In many types of cancer, standard chemotherapy cures only a fraction of patients. Treatments are often too toxic to normal cells and they fail to selectively kill cancer's stem cells, which can survive treatment and, like ...
