Several research topics have emerged: (1) Recurrent mutations were detected in neuronal growth cone genes.
The team found that RNA molecules embedded in the growth cone are responsible for instructing the axon to move left or right, up or down.
Their topics include investigating systems to study the biological effects of weak physiological electrical fields, stem cell physiological responses to noninvasive electrical stimulation, how physiological electric fields can direct keratinocyte migration and promote healing in chronic wounds, inflammatory cell electrotaxis, neuronal growth cone guidance by physiological direct current electric fields, and whether applied voltages can be used to produce spinal cord regeneration and recover in humans.
Further under experimental conditions simulating injury, it was observed that growth cone attraction was not inhibited suggesting that this mechanism could be used to guide neuronal regeneration following axonal injury.
Other topics include quantum dots as cellular probes, microfluidic and microfabricated devices for blood cell separation, growth cone and axonal pathfinding strategies, the mechanics of healing myocardial infarcts, and functional electrical stimulation for neuromuscular applications.
The growth cone is able to move through the environment, sensing structural and chemical cues and laying down the new axon (Fig 1).
The next section focuses on the policy debate in 1960 and Bryan's introduction of a short-term, reserve growth cone as an operating guide.
Between the fourth quarter of last year and June, M2 expanded at an annual rate of almost 5 percent; as the Committee had anticipated, the aggregate was running close to the upper bound of its growth cone, which had been chosen to be consistent with price stability.
The BioScope II mounts directly on an inverted optical microscope, so we were able to get high-resolution images of a neuron's growth cone using AFM that complement and extend the information from fluorescence microscopy," commented Dr.
