Abstract: Developments of cryopreservation techniques on primary rat cortical cells were carried out to observe the effect of cooling rates. Primary rat cortical cells were dispersed in the cryopreserving medium including 5 vol% dimethylsulfoxide, and then they were frozen by various cooling rates ranged from -3 K/min to -150 K/min. The survival ratio was estimated qualitatively by using the phase-contrast microscope. The feasibility of the neural activity was verified by measuring its spontaneous action potential with a multi-electrode array system. Based on these characterizations, the lower cooling rate of the dispersed sample was more feasible for the cryopreservation of the primary rat cortical cells.
