Abstract:
Un dispositivo de estimulación eléctrica (16) para insertar en una microplaca (20), que tiene múltiples pocillos (21) que contienen una muestra (S) que incluye una célula, y aplicar estimulación eléctrica a la célula, comprendiendo el dispositivo de estimulación eléctrica: múltiples pares de electrodos (17), incluyendo cada uno un primer electrodo (17a) y un segundo electrodo (17b), extendiéndose tanto el primer electrodo como el segundo electrodo dentro del pocillo de la microplaca en la dirección de profundidad del pocillo, estando los múltiples pares de electrodos (17) dispuestos en una forma bidimensional correspondiente a la matriz bidimensional de los múltiples pocillos (21) de la microplaca (20) para extenderse hacia los pocillos (21) de la microplaca (20); y una unidad de ajuste de posición (71) adaptada para ajustar simultáneamente las posiciones relativas de una punta del primer electrodo (17a) a una punta del segundo electrodo (17b) en los múltiples pares de electrodos.
Abstract:
A cell observation device is cell observation device for observing a cell held by a microplate having a well holding a sample including the cell and includes a microplate holder for holding the microplate thereon, an electrical stimulation unit including an electrode pair including a first electrode and a second electrode, and a position controller for controlling a position of the electrical stimulation unit in a state in which the first electrode is disposed closer to the center of the well than the second electrode when the electrode pair is disposed in the well of the microplate. The tip of the first electrode extends more than the tip of the second electrode.
Abstract:
A cell observation system 1 is a cell observation system 1 for observing a cell held by a microplate 20 having a plurality of wells 21 arranged therein for holding a sample S including the cell and comprises a microplate holder 11 for mounting the microplate 20, an electrical stimulator 16 arranged with a plurality of electrode pairs 17 including positive and negative electrodes 17b, 17a, and a data analyzer 50 for controlling a position of the electrical stimulator 16 so as to place the electrode pairs 17 within the wells 21 of the microplate 20, while a leading end of the negative electrode 17a on the well 21 side extends longer than a leading end of the positive electrode 17b on the well 21 side.
