Perhaps the most well-known application for preservation of biologic materials occurs in the setting of organ collection and transport for transplantation. The harvest and storage processes for each of the six major solid organs that are frequently harvested for transplantation (kidney, pancreas, liver, heart, lung, and intestines) have similarities and differences.

This article is intended as a brief and general review of biopreservation best practices in the field, with a specific focus on the evolution of optimized preservation solutions.

TISSUE COLLECTION AND STORAGE FOR PROCESSING

The use of these solutions greatly advanced the field of organ transplantation. Its success has prompted the development and use of optimized biopreservation solutions for collection, storage, and transport of other biologic materials, including tissues and cells.

The need for extended cell storage times with improved recovery and viability of biologic source material and derived/isolated cells has been driven largely by the growth of the regenerative medicine market. Because specimens are often shipped among collection, processing, and clinical sites, maintaining therapeutic quality and quantity is paramount. The number of available doses, their potency, and efficacy of the delivered therapy can all be affected by the robustness of the biopreservation media and processes utilized.

CONSIDERATIONS IN REPRODUCTIVE CELL CRYOPRESERVATION – EVIDENCE-BASED PRACTICES

The pioneering discovery in 1948 that glycerol enabled survival of spermatozoa after freezing to minus 70°C represents the foundation of our present understanding of reproductive cryobiology.

Sperm, oocytes, and embryos from a number of mammalian species, including humans, have since been frozen and recovered with mixed success.

The reasons for differential success between oocytes and embryos are not entirely certain; however, variability between species and individuals within a species make it extremely difficult to apply a single cryopreservation method for reproductive cells.

As with other cell types, factors to maximize survival include five things:

Improved Method for Collection and Stability of Umbilical Cord Blood Prior to Processing

In a study, the use of the hypothermic storage solution, HypoThermosol FRS was investigated to determine the feasibility and efficacy for collection and to extend stability of human cord blood.

Biological integrity and usability of birth tissue such as placental and umbilical cord blood and tissue begin to decline postpartum, thereby rendering them essentially unusable as a source of viable tissues and/or cells within minutes to a few hours.

Therefore, in the many cases where trained collection personnel are not on staff or must travel to be on site at the time of delivery, improved the collection and stability methods for preservation of these birth tissues are required to improve stem cell recovery and/or tissue viability.

Improved post-thaw umbilical cord blood cell recovery vs. DMSO/Dextran

Written with Donald L. Hudspeth, BSCLS, MT(ASCP), General and International Projects Manager, Cryobanks International, Inc.

Umbilical cord blood, typically discarded after birth, is a rich source of stem cells that have been transfused into thousands of patients to cure numerous fatal diseases.

In recent years, cord blood transplants (CBT) have become widely recognized as a safe and effective alternative to traditional bone marrow transplants (BMT). Currently, umbilical cord blood stem cells can be used to treat over 75 life-threatening diseases, including leukemias, anemias, lymphomas, and inborn errors of metabolism.

As scientists continue to discover new uses for umbilical cord blood stem cells, many other diseases could potentially be treated using these unique cells.

There are currently more than 700 clinical trials being performed for diseases such as Type I Diabetes, Alzheimer’s, Parkinson’s, stroke, paralysis, heart disease, and wound repair, according to Cryobanks International.

Making your own biopreservation media may be costing you more than you realize!

Biopreservation of cells, tissues, and organs is a frequently applied and required practice used to extend the stability and viability in both short-term and long-term storage of samples for research and clinical applications.

Outside of storing cells at normothermic temperatures (37°C growth conditions), most practitioners utilize either hypothermic biopreservation or cryopreservation methods.

Hypothermic biopreservation is typically performed at temperatures above 0°C and usually between 2-10°C, but certainly below ambient (around 22°C) or normothermic conditions. It is used for short-term transport and storage, during which metabolic activity is greatly reduced but still present at some level.

Cryopreservation, or frozen storage, involves long-term storage of biologics at or below -80°C (typically below -140°C) in conditions of metabolic arrest.

A study to collect quantitative data to better characterize the safety profile of HypoThermosol and CryoStor from BioLife.

The FDA or other agencies do not regulate biopreservation media products as drugs, devices, biologics, or combination products.

  • They are considered “ancillary material” when used in the manufacturing of cell, gene, or tissue-engineered products, but are not intended to be in final product (washed or removed).
  • Or they are considered “excipient components” intended to be part of the final product and in contact with the patient.

Although the commercial history of cell therapy is not as extensive as the broader biotherapeutic market, a number of parallels can be drawn between the two.

In the early 1980’s it was clear to many scientists that commercially manufactured therapeutic grade antibodies could have a significant benefit if used as ligand-mimetic agonists or antagonists of important signaling pathways.
