Growing A Brain: Two-Step Control Mechanism Identified in Mouse Stem Cells

uni of tokyo

Tokyo, Japan – Scientists identified two distinct control mechanisms in the developmental transition of undifferentiated stem cells into healthy brain cells. This fundamental research using mice may inform regenerative medicine treatments for neurodegenerative diseases and spinal cord injuries, in the future.

How Sperm Stem Cells Maintain Their Number

NIBB news

Tokyo, Japan – The steady production of sperm relies on the number of sperm stem cells in the testis remaining constant. Researchers including Asst. Prof. Yu Kitadate and Prof. Shosei Yoshida [developmental biologists at the National Institute for Basic Biology (NIBB) within the National Institutes of Natural Sciences in Japan] and Prof. Benjamin Simons (a theoretical physicist at the University of Cambridge in the UK) have revealed a novel mechanism for stem cell number control.

An Important Step for Regenerative Medicine: Human Blood Cells can be Directly Reprogrammed into Neural Stem Cells

DKFZ news

Heidelberg, Germany – Scientists from the German Cancer Research Center (DKFZ) and the stem cell institute HI-STEM in Heidelberg have succeeded for the first time in directly reprogramming human blood cells into a previously unknown type of neural stem cell. These induced stem cells are similar to those that occur during the early embryonic development of the central nervous system. They can be modified and multiplied indefinitely in the culture dish and can represent an important basis for the development of regenerative therapies.

New Rutgers Research Achieves Important Milestone to show how newly created cardiac muscle cells can be made to pump together

New Brunswick, NJ, USA – A team of Rutgers scientists, including Leonard Y. Lee and Shaohua Li, have taken an important step toward the goal of making diseased hearts heal themselves – a new model that would reduce the need for bypass surgery, heart transplants or artificial pumping devices.

The Immune System's Supercell – How It Matures

lund news

Lund, Sweden – NK cells, or natural killer cells, play an important role in the body's defences against cancer and various infections. Now, in a joint project, researchers at Lund University in Sweden, the University of Oxford and Karolinska Institutet in Stockholm have mapped how the different steps of the maturation process of these supercells from blood producing stem cells in the bone marrow are regulated: knowledge which is crucial for the development of new immunotherapies against cancer.

New Method For Studying ALS More Effectively

karolinksa

Stockholm, Sweden – The neurodegenerative disease ALS causes motor neuron death and paralysis. However, long before the cells die, they lose contact with the muscles as their axons atrophy. Researchers at Karolinska Institutet have now devised a new method that radically improves the ability to study axons and thus to better understand the pathological development of ALS.

The Source of Stem Cells Points to Two Proteins

East Lansing, MI, USA – Mammalian embryos are unlike those of any other organism as they must grow within the mother’s body. While other animal embryos grow outside the mother, their embryonic cells can get right to work accepting assignments, such as head, tail or vital organ. By contrast, mammalian embryos must first choose between forming the placenta or creating the baby.
