| 1. | Similarly , xenopus spinal growth cones turned away from a gradient of baclofen , an agonist of the gabab receptor
同样的， gabab受体的激动剂baclofen的浓度梯度也能够吸引或排斥爪蟾脊髓神经元的生长锥。 |
| 2. | In mature neuronal network , nogo - a immunoreactive axons showed a string of beads which correspond to the varicosities or growth cones
Nogo a在成熟的神经元网状的突起上，呈串珠样分布，这些结构推测为膨体或生长锥。 |
| 3. | Then , nogo - a expression was gradually enriched in the distal segment and growth cone of the putative axon which grew much faster than other neurites
神经元突起形成过程中， nogo a主要表达于树突近端，在轴突上随着轴突的伸长逐渐表达于轴突远端和生长锥。 |
| 4. | Because the charge must be released by the silicon neuron and sensed by the silicon growth cone simultaneously , the softwires end up connecting neurons that are active at the same time
因为矽神经元释出的电荷必须同时被矽生长锥侦测到，结果软线就将同时活跃的矽神经元连结在一起。 |
| 5. | It was reported that the growth cone of xenopus embryonic neurons might response to a 7mv / mm electric signal and extend to the cathod ; also , neuronal differentiation was enhanced in the existence of electromagnetic field
Cntf和il一1a对中脑神经前体细胞神经元向分化的效应与浓度有关： cntf0 |
| 6. | Agrin inhibits rac activity in developing neurons and expression of dominant negative rac1 abolishes agrin - induced growth cone turning and substantially inhibits neurite extension
我们的实验也表明， agrin抑制发育中神经元rac的活性。 dn - rac1的表达完全阻断了agrin引起的生长锥导向，并抑制突起的生长。 |
| 7. | The silicon growth cones sense this simulated diffusing “ chemical ” and drag their softwires up the gradient ? toward the charge ' s silicon neuron source ? by updating the look - up table
矽生长锥侦测到这种扩散的刺激性化学物质后，就会更新查询表，并且将软线移向高浓度的地方，也就是朝释出电荷的矽神经元源头前进。 |
| 8. | Expression of either dominant negative or antisense musk in cultured xenopus laveis spinal neurons abolishes agrin - induced neurite outgrowth inhibition and converts chemorepulsive growth cone turning induced by a gradient of agrin into chemoattraction
Musk突变体（ dm - musk ）或反义musk ( as - musk )的表达，解除了agrin对新生突起生长的抑制，并且把agrin诱导的排斥反应反转为吸引反应； musk介导发育中神经元突起的生长。 |
| 9. | Here we report that growth cones of rat cerebellar axons in culture turned away from a gradient of sdf - 1 , a chemokine that attracts migrating leukocytes and cerebellar granule cells via a g protein - coupled receptor ( gpcr )
以前的证据表明， sdf - 1 ，一种经典的chemokine ，能够吸引白细胞和迁移中的神经元，这种作用是通过g蛋白耦联受体介导的。利用生长锥转向分析，我们发现sdf - 1的浓度梯度能够吸引或排斥培养的小脑颗粒细胞的生长锥。 |
