Importance of cryopreservation in biobanking

Biobanks play a crucial role in the collection, storage, and management of biological samples, such as blood, tissues, and DNA, which are used for various research purposes, including understanding the genetic basis of diseases, drug development, and biomarker discovery. With the advancements in biotechnology and data science, it has become easier to collect, store, and analyse large volumes of biological data. This has enabled researchers to extract valuable insights from biobank samples more efficiently, it has also increased the demand for well-curated and diverse biobanks.

Biobanks have enabled the accelerated study of disease pathways and potential drug targets leading to an increase in drug development, they also play a crucial role in collecting samples with relevant biomarkers, facilitating ground-breaking research in this area. However enable sample quality is key and cryopreservation plays a crucial role in biobanking. The importance of cryopreservation in biobanking stems from its ability to preserve the viability, functionality, and integrity of biological samples for an extended period of time. 

Long-term sample preservation is key in successful biobanking and cryopreservation allows biological samples, such as cells, tissues, and biological fluids, to be stored at extremely low temperatures (typically below -150°C) for extended periods. This ensures that samples can be kept viable and functional for years, sometimes even decades. Such long-term preservation is critical for longitudinal studies, rare disease research, and the investigation of conditions that require long observation periods. Sample preservation is key as biobanks house a diverse range of biological samples from various populations, species, and disease states. Cryopreservation enables biobanks to store a vast array of samples, ensuring a wide range of genetic, phenotypic, and disease-related data are available to researchers and clinicians.

Research continuity and reproducibility is key and  allows researchers to store samples from a specific time point, enabling future replication and verification of experimental results. This enhances research continuity which is key when samples are supporting ground-breaking research which can lead to life changing treatments and disease prevention, where the reproducibility of findings is essential.

Cryopreserved samples are a valuable resource for personalized medicine initiatives and drug development. Researchers can use these samples to understand individual patient responses to treatments, identify biomarkers, and develop targeted therapies based on a patient's unique genetic and biological profile. This is an area where sample volume may be low so maximising viability of the sample is essential. Some biological samples, such as those from rare diseases or endangered species, may be difficult to obtain. Cryopreservation ensures that these samples are available for research, diagnostics, and conservation efforts, without the need for continuous sample collection.

Cryopreservation techniques are well-established and standardized in the biobanking community. This ensures that samples are stored and handled consistently, maintaining their quality and integrity over time. Biobanks that employ cryopreservation can act as valuable resources during emergencies or natural disasters. Cryopreserved samples can be transported to other locations or even to different countries, ensuring the continuity of research and healthcare efforts.

In summary, cryopreservation is of paramount importance in biobanking as it enables the long-term preservation of diverse biological samples, facilitates research continuity, supports personalized medicine and drug development, and upholds ethical considerations while enhancing the overall quality and reliability of research and diagnostic endeavours. So when choosing a cryopreservation approach it is key that maximising cell viability is a key consideration, additional to freezing the sample it is also important to consider thawing as this is where samples can be mishandled and at this point certainty and trust in approach is fundamental to success.
