“…This high-molecular non-penetrating cryoprotectant causes dehydration of cells at the equilibration stage, thereby diminishing the intracellular crystallization at subzero temperatures. On the other hand, due to its high extracellular concentration this cryoprotectant immobilizes the molecules of a huge amount of extracellular water, resulting in an inhibition of extracellular crystallization and a decrease of membrane damage by ice crystals (11). Despite these beneficial impacts of PEO-1500 against freezing, its final removal from the erythrocyte suspension resulted in almost full hemolysis (Figure 2).…”

“…Whereas structural and functional characteristics of membrane after cryopreservation can change [22], we assumed that a decrease in osmotic load at the проблеми кріобіології і кріомедицини problems of cryobiology and cryomedicine том/volume 28, №/issue 3, 2018 матозоида в ооцит зависит от тургора клетки, который определяется структурно-функциональными характеристиками оолеммы. В результате возможны вариации степени ее инвагинации, которые могут служить предикторами оплодотворения ооцитов и образования зигот [18,24]. Поскольку структурно-функциональные характеристики мембраны после криоконсервирования могут изменяться [5], мы предположили, что снижение осмотической нагрузки на этапе выведения криопротектора из клетки позволит сохранить функциональные характеристики оолеммы.…”
