Gene keeps neural cells on correct developmental path
Embryonic stem cells with identical genomes grow into distinctive tissues, such as heart, bone, and brain. At one time, scientists believed the differences among cell types arose from various sets of genes switched on inside developing cells. Then, studies showed that adult neurons uniquely lack a protein that permanently turns off neuronal genes in the rest of the body's cells. Now, it tu...Researchers discover stem cell 'guide' that may be key for targeting neural stem cell treatments
UC Irvine School of Medicine researchers have discovered how new neurons born from endogenous neural stem cells are sent to regions of the brain where they can replace old and dying cells, a finding that suggests how stem cell therapies can be specifically targeted to brain regions affected by neurodegenerative diseases or by stroke. Associate Professor Qun-Yong Zhou and graduate student K...Gambling monkeys give insight into neural machinery of risk
Duke University Medical Center neurobiologists have pinpointed circuitry in the brains of monkeys that assesses the level of risk in a given action. Their findings -- gained from experiments in which they gave the monkeys a chance to gamble to receive juice rewards -- could give insights into why humans compulsively engage in risky behaviors, including gambling, unsafe sex, drug use and overeatin...Brain size may depend upon how neural cells are cleaved
Howard Hughes Medical Institute researchers have discovered a novel way in which the brain size of developing mammals may be regulated. They have identified a signaling pathway that controls the orientation in which dividing neural progenitor cells are cleaved during development. The way these cells are sliced during development is critical because at later stages of neurogenesis, vertical...Defect in gene causes 'neuralgic amyotrophy'
Neuralgic Amyotrophy is a painful disorder of the peripheral nervous system. This heritable disease causes prolonged acute attacks of pain in the shoulder or arm, followed by temporary paralysis. Researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to the University of Antwerp, have uncovered a small piece of the molecular puzzle of this disease by identifyin...NeuroCyte - Rat Neural Stem Cell Kit from Orion BioSolutions, Inc.

Description:Stem cells are functionally defined by their capacity to self renew and their ability to differentiate into multiple specialized progenitor cells, which can commit to further maturation along specific lineages. Neural stem cells (NSCs) are capable of differentiating into multiple cell types including astrocytes, neurons and oligodendrocytes. During the isolation and expansion of NSCs, the status...Your Data: Silencing Neural Cell Adhesion Genes with In Vitro Transcribed siRNAs
Ambion has developed a system for siRNA synthesis and purification based on in vitro transcription, the siRNA Construction Kit (patent pending). This kit produces transfection-ready siRNA at a fraction of the cost of chemical synthesis. Here, resear...DHEA Boosts Growth Rate of Human Neural Stem Cells
MADISON - Human neural stem cells, exposed in a lab dish to the steroid DHEA, exhibit a remarkable uptick in growth rates, suggesting that the hormone may play a role in helping the brain produce new cells, according to a new study published this week in the online editions of the Proceedings of the National Academy of Sciences (PNAS). The new work, conducted by a team of scientists at t...New technology to decipher neural connections dealing with heredity and environment
A study by the computational neuroscientist of Vanderbilt University have developed a new computer model// that will provide an insight into neural circuits that play a role in development. The computer model traces the neural circuits that make us apply previously learned rules on new situations and help in self-control. The researchers feel that the new use of technology in understa...Gamma Knife Offers New Hope For Trigeminal Neuralgia Patients
There is now new hope on the horizon for trigeminal neuralgia patients as researchers have found that Gamma Knife Stereotactic Radiosurgery (GKRS) is an effective way to deal with the pain caused by the condition.// Researchers at the Comprehensive Cancer Center at Wake Forest University Baptist Medical found that the GKRS technique relived pain to a considerable degree in a study of...Fetal Neural Grafts Improves Motor and Cognitive Function in Huntington Patients
Anne-Catherine Bachoud-Lévi, M.D., and colleagues of the French national institute of health and medicine reported in The Lancet that Huntington's disease// who previously received intracerebral fetal neural grafts had improvements in both motor and cognitive function. But the same investigators reported today that the improvements in Huntington's disease patients plateaued after two y...A boon to the paralyzed -Brain Gate Neural Interface System
It will now be possible for a patient with spinal cord injury to produce brain signals that relay the intention of moving the paralyzed limbs// , as signals to an implanted sensor, which is then output as electronic impulses. These impulses enable the user to operate mechanical devices with the help of a computer cursor. A report appearing in the July 13 issue of Nature includes the...
