Cryogenic preservation plays a central role in cellular therapy, long-term biological storage, regenerative medicine, and advanced manufacturing of therapeutic cell lines. This study investigates how varying cooling rates, cryoprotectant concentrations, and thaw-recovery procedures influence viability and functionality in human-derived cell samples.
The intervention consists of laboratory-controlled freeze-thaw cycles at temperatures ranging from -80 °C to -196 °C under defined standard and experimental conditions. Post-thaw evaluations include viability assays, growth kinetics, apoptotic markers, metabolic profiling, and structural assessment.
The study is non-clinical and does not involve living human subjects. All cell materials are obtained under appropriate consent or supplied as commercially available research-grade lines.
