Cell model of the brain provides new knowledge on developmental disease

By reprogramming skin cells into nerve cells, researchers at Karolinska Institutet are creating cell models of the human brain. In a new study published in Molecular Psychiatry the researchers describe how cells from patients with the severe developmental disease lissencephaly differ from healthy cells. The method can provide vital new knowledge on difficult-to-study congenital diseases.

Human skin cells transformed directly into motor neurons

Scientists have converted skin cells from healthy adults directly into motor neurons without going through a stem cell state. The technique makes it possible to study motor neurons of the human central nervous system in the lab. Unlike commonly studied mouse motor neurons, human motor neurons growing in the lab would be a new tool since researchers can’t take samples of these neurons from living people but can easily take skin samples.

Zika virus kills brain cancer stem cells

While Zika virus causes devastating damage to the brains of developing fetuses, it one day may be an effective treatment for glioblastoma, a deadly form of brain cancer. New research shows that the virus kills brain cancer stem cells, the kind of cancer cells most resistant to standard treatments.

A new method of 3D printing living tissues

Scientists at the University of Oxford have developed a new method to 3D-print laboratory-grown cells to form living structures. The approach could revolutionize regenerative medicine, enabling the production of complex tissues and cartilage that would potentially support, repair or augment diseased and damaged areas of the body.

Using barcodes to trace cell development

How do the multiple different cell types in the blood develop? Scientists have been pursuing this question for a long time. According to the classical model, different developmental lines branch out like in a tree. The tree trunk is composed of stem cells and the branches are made up of various types of progenitor cells that can give rise to a number of distinct cell types. Then it further branches off into the specialized blood cells, i.e., red blood cells, blood platelets and various types of white blood cells that are part of the immune system. In recent years, however, doubts about this model have arisen.
