It is now 45 years since Planer was founded. To mark the occasion, we have been taking a look at our archives to see how cryopreservation and its applications have developed over these four decades.

By the 1970s new forms of cryobiology were emerging around the world. Planer were at the forefront of this field and one of our first equipments is shown here with Professor David Pegg, a founding father of the science. These early controlled rate freezers allowed samples, till then difficult or impossible to deep freeze successfully, to be slowly frozen down in controlled ramps within a cryo-protective solution, for storage in liquid nitrogen and later use.  An early success was the first birth from a frozen bovine embryo.

In 1984 in Melbourne, Australia the first human baby from a frozen embryo was born, helped on her way by Drs Alan Trounson and Carl Wood using a Planer freezer. Around the same time, as assisted human fertility became established as a science, human sperm started to be routinely banked for later use, not usually stored as long as in one case, where a sample slow frozen using a Planer Kryo 10 in Canada was used to give a healthy baby – twenty two years later.

In 1986 the first successful freezing of a human oocyte was reported by Dr Christopher Chen in the Lancet, again using a Planer controlled rate freezer, the research continued and in 1991 arterial graft material was frozen successfully for the first time using Planer rate freezers. And as the bio-banking industry expanded, controlled rate freezing became a more mainstream technology - routinely employed around the world.

Many different types of cells, including cord blood, bone marrow, semen, skin, ovarian tissue, heart valves and blood vessels are controlled rate frozen and carefully stored in the cryogenic systems we supply and service. As their sample numbers increase many users take advantage of our DeltaT software which allows them to deploy one profile to several freezers, with those profiles being displayed on the same graph and each run having a time stamped compliant summary.

Investigations continue into new areas of preservation such as controlled vitrification or the mechanics of freezing such as the monitoring of freezing rates – and so Planer equipment continues to help in key developments, new treatments and scientific breakthroughs around the world.

Society of Low Temperature Biology SLTB

The 2018 Society for Low Temperature Biology (SLTB) meeting will be taking place at the Crop Research Institute, Prague on the 6thand 7th September 2018.

The Society was founded in 1964 with the purpose of promoting research into the effects of low temperatures on all types of organisms and their constituent cells, tissues and organs. Such studies have applications in diverse scientific fields, from biology and medicine to engineering, conservation and environmental science.

SLTB members come from a range of disciplines, but all share a common interest in understanding relationships between low temperatures and biological systems. The objectives of the SLTB are:

  1. To advance the education of the public in the science of low temperature biology.  
  2. To advance the science of low temperature biology. 
  3. To promote research into the science of low temperature biology and; 
  4. Disseminate the useful results to the public.

Topic areas range from natural mechanisms of cold tolerance, the cryopreservation of cells and tissues for medical, agricultural and conservation purposes, low temperature microscopy, through to the physics and physical chemistry of water and ice; and heat and mass transfer in all types of biological systems.

As a pioneering company within this field Planer will be attending this meeting to demonstrate our latest Cryogenic equipment.

Dr Carmela AlbertIVI fertility group, headquartered in Valencia Spain, treats around 5,000 couples from 80 countries each year. Lab director Dr Carmela Albert (pictured here) and colleagues published a poster at the 2018 Alpha Congress in Iceland.

The poster looked at the role of humidity in the incubation process. Dr Carmela Albert, et al, from IVI, looked at the optimal conditions in incubators for embryo culture. For many incubators, oil overlay has supported successful use of a dry incubator for culture human embryos, preventing changes in the pH and temperature.

Since in vivo culture conditions are humid the aim of the study was to know how high humidity might affect embryo development. So experiments were carried out in a Geri® incubator comparing dry conditions to humid, performing a detailed analysis with a continuous embryo monitoring system. The results strongly suggested that culture conditions with high humidity atmosphere promoted embryo development and reproductive outcome.

Europe Biobank Week 2018

At the beginning of September, Planer will be sharing an exhibition space at the "Europe Biobank Week 2018: Biosharing for Scientific Discovery" conference with CryoSolutions. Co-organised by BBMRI-ERIC and ESBB, Europe Biobank Week 2018 will take place in Antwerp, Belgium, from the 4th until the 7th September 2018.

Europe Biobank Week (EBW) is one of the most significant biobanking conferences worldwide. This event provides an exciting and unique opportunity for the biobanking community to discuss the future challenges for biobanking, network and explore new prospects for cooperation and collaboration. While last year’s conference focussed on harmonisation, the theme for 2018 will be Biosharing for Scientific Discovery.

We look forward to welcoming biobanking experts, scientists, policy makers, patient representatives, and the wider scientific community at Europe Biobank Week in Antwerp and hope to see you on our stand number 35.

Biobanking in the 21st CenturyWith Europe Biobank Week 2018 in Antwerp, Belgium coming up (September 4-7th) people will be reviewing the available information on the subject. A definitive book is published by Springer - and of the fourteen chapters, chapter five, "The Future of Cell Preservation Strategies" by John M. Baust et al will probably interest our customers.

Dr Baust introduces this subject: " ... cryopreservation is often viewed as an “old school” discipline yet modern cryopreservation is undergoing another scientific and technology development growth phase. In this regard, today’s cryopreservation processes and cryopreserved products are found at the forefront of research in the areas of discovery science, stem cell research, diagnostic development and personalised medicine. As the utilisation of cryopreserved cells continues to increase, the demands placed on the biobanking industry are increasing and evolving at an accelerated rate. No longer are samples providing for high immediate post-thaw viability adequate. Researchers are now requiring samples where not only is there high cell recovery but that the product recovered is physiologically and biochemically identical to its pre-freeze state at the genominic, proteomic, structural, functional and reproductive levels".

He continues "It is often unappreciated that in order for a cell to be successfully cryopreserved the cell itself must avoid freezing, therefore remaining in a state of deepening hypothermia until glass transition temperature is reached. In essence, for a cell to be successfully cryopreserved, it must remain in a ultra-cold liquidous state until transitioning to a glassy state. Generally speaking, if ice forms within a cell during any part of the process, survival will be compromised. Cryoprotective agents (CPAs) function, in part, to lower the probability of intracellular ice formation.... today's CPAs include a variety of penetrating (membrane permeable) and non-penetrating compounds contained in an appropriate cell culture media with or without serum."

The science of Biobanking, which initially involved simply storing blood or tissue samples in a freezer, is now a highly sophisticated field of research, and expected to grow exponentially over the next decade or two. The book aims to enrich the available literature by offering a useful collection of ideas for the future. It outlines the experiences of developing modern Biobanking repositories in different countries, whilst covering specific topics regarding its many aspects.

Transplantation with adipose tissue derived stem cells increased follicle survival in frozen–thawed human ovarian tissue. 

A recent paper published in 'Human Reproduction' by Diego Manavella et al looked at a two-step transplantation process using adipose tissue derived stem cells in which they found increased follicle survival by enhancing vascularization in xenografted frozen–thawed human ovarian tissue.

The team from the Gynaecology Research Unit, Institut de Recherche Expérimentale et Clinique, UCL Louvain, who use Planer controlled rate freezers, found that higher rates of oxygenation and vascularization of ovarian tissue, as well as increased follicle survival rates, were detected in the early post-grafting period. The results suggested that the proposed transplantation procedure with ASCs is a promising step towards potentially solving the problem of massive follicle loss after ovarian tissue grafting.
