1. Fazer agulhas de vidro. <ol><li> Um extrator de micro-agulha ajustável é usado para fabricar agulhas com ponta cônica de cerca de 4 mm de comprimento e que estão fechados vigas sólidas. Em oposição a uma ponta longo e flexível, esta curta 4 mm de comprimento limites vibrações da ponta da agulha durante as experiências. Na região proximal da fibra de 4 mm, a agulha se reduz rapidamente a partir do diâmetro do tubo de vidro de 15 mm em 1 mm, enquanto que o distal mais de 1 mm da fibra é de 2,5 m de di...

Técnicas para aplicar e medir forças celulares têm uma longa história 9. Nosso método foi originalmente motivado pelo trabalho de Dennis Bray, que usou agulhas de vidro semelhante ao nosso para &quot;rebocar&quot; os neurônios em uma taxa constante através de um dispositivo motorizado hidráulico 10. Existem muitos meios alternativos de aplicação de forças para as células que incluem: motores de passo 11, 12 esferas magnéticas, vigas microfabricated 13 e fluxos de ...

mechanical manipulation of neurons to control axonal development

Manipulações de células e extensão de axônios neuronal pode ser realizado com vidro calibrado micro-fibras capazes de medir e aplicação de forças na faixa de 1,2 1-10 μdyne. Medidas de força são obtidos através da observação da Hookean flexão das agulhas de vidro, que são calibrados por um método direto e empírica 3. Requisitos de equipamentos e procedimentos para a fabricação, calibração, tratamento e usando as agulhas sobre as células estão completamente descritos. A força de regimes tipos de células usadas anteriormente e diferente para que estas técnicas foram aplicadas demonstrar a flexibilidade da metodologia e são dados como exemplos para futuras investigações 4-6. As vantagens técnicas são as &quot;visualização&quot; contínua das forças produzidas pelas manipulações ea capacidade de intervir diretamente em uma variedade de eventos celulares. Estes incluem a estimulação direta e regulação do crescimento axonal e retração 7, assim como desapego e medições mecânicas em qualquer tipo de células cultivadas 8.
