An apparatus for detecting chemotaxis of cells which aims at easily carrying out the injection of the cells and the position control with the use of a small amount of cells and surely preventing the cells or a sample injected in a definite part of a well from unexpected migration. This apparatus for detecting chemotaxis of cells, in which two wells are connected to each other via a channel being resistant to the passage of cells and each well has an opening for injecting cells or a sample thereinto, is characterized by: (1) having a means of transporting a liquid and a means of stopping the transportation after the injection or aspiration discharge of the liquid; and (2) having a means of blocking opening (s) in one or both of the cell- injection side and the sample-injection side.

Selon l'invention, un appareil pour détecter le chimiotactisme des cellules vise à effectuer aisément l'injection et le positionnement de cellules grâce à l'utilisation d'une faible quantité de cellules; il empêche de manière sûre la migration inattendue des cellules ou d'un échantillon injecté dans une partie définie d'un puits. Cet appareil destiné à la détection du chimiotactisme des cellules, dans lequel deux cellules sont connectées entre elles via un canal qui résiste au passage des cellules et chaque puits possède une ouverture destinée à l'injection de cellules ou d'un échantillon, est caractérisé en ce que: (1) il possède un moyen pour transporter un liquide et un moyen pour freiner le transport après l'injection ou la décharge d'aspiration du liquide et; (2) en ce qu'il possède un moyen pour obturer la ou les ouverture(s) d'un ou des deux côtés d'injection de cellules et du côté d'injection d'échantillons.
