A quartet of genes controls growth of blood stem cells
An important element in getting blood stem cells to multiply outside the body is to understand which of the approximately 20 000 genes in the human body control their growth. A research team at Lund University in Sweden has studied close to 15 000 of these genes alongside each other. The researchers have succeeded in identifying four key genes which, together, govern the growth and multiplication of the stem cells. The study is now being published in the journal Cell Reports. Every day, over...

A microtubule 'roadway' in the retina helps provide energy for vision
Researchers have discovered a thick band of microtubules in certain neurons in the retina that they believe acts as a transport road for mitochondria that help provide energy required for visual processing. The findings appear in the July issue of The Journal of General Physiology. The retina is a layer of tissue in the back of the eye that converts light into nerve impulses. The retina contains small, specialized neurons called bipolar cells that transmit information from light-sensitive...
