2019 Ovarian Club CongressThe Ovarian Club XIV Congress will be taking place in Paris from the 7th-9th November at the Westin Paris – Vendôme. The Ovarian Club brings together scientists, clinicians and embryologists who have a common interest in all facets of ovarian function, including oocyte and early embryo development and the implantation process. At this year’s meeting there Is also a pre-congress fertility preservation workshop, chaired by Professor Dror Meirow, with a particular focus on ovarian tissue cryopreservation and transplantation.

Planer is delighted to support this year’s Ovarian Club meeting. Come and talk to our team to find out more about:-

Ovarian tissue cryopreservation and transplantation workshop at PRSM
Recently Professor Dolmans and Christiani Amorim, from the Université Catholique de Louvain (UCLouvain) in Belgium, led a workshop on the cryopreservation and transplantation of human ovarian tissue at the Pacific Society for Reproductive Medicine (PSRM) conference. The 2019 PSRM conference, which is a biennial event, was held this time in the Royal Cliff Hotel, Pattaya, Thailand.

The UCLouvain team has worked for many years on researching and developing the techniques required for the successful cryopreservation and transplantation of ovarian tissue. They now run workshops and courses around the world to help increase the understanding and use of this important fertility preservation technique.

The course, impeccably organised by Professor Paweena Thuwanut, was attended by participants from clinical centres, from the Pacific region, demonstrating that this technique, despite still being considered experimental in some countries, is growing in popularity. The worldwide number of successful live births recorded continues to grow year-on-year as this technique becomes more widely available.

The team at the University uses a Planer Kryo 360 -1.7 to perform the cryopreservation of the ovarian tissue as this has proven to provide consistent successful results. There are now many centres around the world that have reported the benefits of slow freezing when cryopreserving ovarian tissue and Planer is proud to be associated with this important technique that can result in many women going on to have children, sometimes naturally, even after cancer treatment.

The team from UCLouvain is already planning further courses, including a one day workshop on Thursday 14thNovember at the 2019 International Society for Fertility Preservation conference in New York.

Advances in the science of ‘cryobanking’ animal gametes are helping restore endangered populations and preserve biodiversity, writes Professor William V Holt in a recent edition of The Biologist, the Royal Society of Biology’s Magazine.

The Biologist Article - Frozen Assets. Advances in the science of cryobanking animal gametesIn the late 1940s a young postdoc called Chris Polge, working at the MRC laboratories in north London, made the fortuitous but accidental discovery that mammalian and fowl sperm could be frozen and thawed successfully in the presence of glycerol.

This breakthrough led to the large-scale application of semen cryopreservation in cattle breeding and the complete transformation of the global dairy industry, which nowadays relies almost entirely on the use of frozen semen and artificial insemination for cattle breeding.

Semen freezing has also been used successfully to preserve fertile sperm from numerous wild mammals, fishes, amphibians and birds. The realisation that, in principle, it is feasible to collect sperm from diverse species and keep them in liquid nitrogen (-196ºC) has led several research groups to envisage the systematic collection and storage of semen from many of the species heading towards extinction.

Whilst relatively straightforward, the success of freezing fish and amphibian sperm has permitted the serious development of sperm-based genome resource banks for these species, the same cannot be said for their oocytes. However, by refocusing their approach, some research groups have been remarkably successful in exploring the possibility that various types of germ cells could be extracted from either ovaries or testes, frozen and stored, and then used to repopulate the ovaries and testes of recipient animals.

Looking to the future, researchers are now searching for new, innovative ways to preserve viable genomes for animal breeding.

Professor David Pegg - one of the founding fathers of cryobiologyWe, at Planer, were much saddened to hear of the passing of Professor David Pegg on the 3rd August 2019.

David qualified with Bachelor of Medicine (MB), BSc in 1956 and Medical Doctorate (MD) in 1963 and was awarded the William Julius Mickle Fellowship of the University of London in 1968. He passed his Membership to the Royal College of Pathology (MRCPath) in 1967 and his Fellowship (FRCPath) in 1998 for research in experimental pathology.

David was one of the founding fathers of the science of modern cryobiology and he worked with Planer on some of the very first controlled rate freezers in the early 1970s. He is fondly remembered by some members of staff, still at Planer, who worked alongside him during that time. Geoffrey Planer said “Apart from owing a deep gratitude to David, I will greatly miss the interaction with him which was always stimulating – scientifically, and indeed, generally. Like many brilliant people, he could engage in fascinating conversations on subjects well outside his academic field as easily as he could within his technical specialities”.

David, pictured here with an early Planer freezer, published over 200 peer reviewed papers and numerous books focusing primarily on tissue preservation and cryobiology.  His contributions to the field are numerous, notably in the development of effective cooling techniques and cryoprotectant use to avoid ice formation.

The memorial service for David was held on Thursday 29th August in The Hospitium in the Museum Gardens in York, followed by a gathering when people met and shared their memories of working and socialising with David over the years.
