[Effect of various factors during cryopreservation on the morphology and viability of several poikilothermic cell lines]. / Efecto de varios factores durante la criopreservación sobre la morfología y la viabilidad de algunas líneas celulares poikilotérmicas.

This paper deals with the effect of several factors, during cryopreservation, on three poikilothermic cell lines using morphology and viability as indicators. It was proved that to avoid toxicity in the suspension medium is of vital importance for the outcome of freezing. In addition, one of the systems studied and of great application in Virology does not bear long hibernations. Finally, the most adequate freezing method for this type of cells is discussed.
