Cancer Cells Resort to Cannibalism To Survive Chemo
By “consuming” neighboring cancer cells, some cells have found a way to obtain the energy they need to remain alive and induce relapse after a course of chemotherapy is completed.

Bone Marrow May Be the Missing Piece of the Fertility Puzzle
Study shows that when an egg is fertilized, stem cells leave the bone marrow and travel via the bloodstream to the uterus, where they help transform the uterine lining for implantation.

Alzheimer's Risk Gene Targets the Brain's Immune Cells
The most prevalent genetic risk factor of Alzheimer's disease (AD), apolipoprotein E4, impairs the function of human brain immune cells, microglia.

Researchers Use CRISPR to Correct Mutation in Duchenne Muscular Dystrophy Model
Duchenne muscular dystrophy (DMD) is a rare but devastating genetic disorder that causes muscle loss and physical impairments. Researchers at the University of Missouri School of Medicine have shown in a mouse study that the powerful gene editing technique known as CRISPR may provide the means for lifelong correction of the genetic mutation responsible for the disorder.

Failed drugs often are left on the shelf to gather dust. But sometimes, drugs can be dusted down and repurposed. In this article, we profile a new effort to bring drugs back from the dead and find solutions to conditions such as multiple sclerosis and chronic pain.
A number of projects are underway to harness bioprinting to print functional human tissues, the first step to printing an entire organ. In this article, we take a closer look at three of these projects.
Blood vessels and astrocytes in aging rat retina, confocal imaging, 40x. Blood vessels are shown in blue; astrocytes (supportive cells of the nervous system) are mostly in red. As organisms age, changes in astrocytes might contribute to disease and degeneration.
