“…The cell culture conditions used here favour the growth of primary fibroblast cells. Fibroblasts are one of the most used cells types for somatic nuclear transfer (Kues and Niemann, 2004;Andrabi and Maxwell, 2006;Trounson, 2006). Cloned offspring have been obtained from long-term cell cultures and even from senescent cells.…”

“…The authors are aware that the NT technique needs further improvements to reach practicability for large-scale cloning. Recent developments support the notion that the need of a costly micromanipulation unit can be substantially reduced (Vajta et al, 2004), and that NT-associated problems, such as overall low success rates, might be reduced (Andrabi and Maxwell, 2006;Trounson, 2006;Wilmut, 2006).…”

A protocol was developed for collection and storage of somatic cell samples under adverse conditions with little infrastructure, for somatic-cell banks as a backup for endangered livestock breeds. The procedure, which is uniform across species, includes sample collection with ear taggers with an integrated tag/vial system, and recording of global positioning system (GPS) coordinates, digital images and breed information. In a pilot study, the procedures were tested on six local Vietnamese populations of pigs, sheep and goats. Initial investment was around h3000, while the total variable cost for sampling one breed with 25 females and 25 males was less than h1000. With support from local organisations, the sampling of six breeds with 300 animals was carried out in 2 months. The protocol and the complete workflow for setting up a somatic-cell bank, together with data collection, are described. The procedure has proved practicable and exceedingly cheap relative to the cryopreservation of semen or embryos.

Protecting the reproductive potential of young patients undergoing cancer therapy is increasingly important. With modern treatment protocols, 80% of patients can be expected to survive. It has been estimated that up to one in 250 young adults will be a survivor of childhood cancer in the future; infertility, however, may be a consequence. As a wide range of fertility preservation methods are increasingly offered by clinicians, this systematic and comprehensive textbook dealing with the cryobiology, technology and clinical approach to this therapy will be essential reading to infertility specialists, embryologists, oncologists, cryobiologists, ObGyns, andrologists, and urologists with an interest in fertility preservation. Fertility Cryopreservation reviews all the techniques of this increasingly important field within reproductive medicine. It covers the basic principles of pertinent cryobiology, and contains major sections on the different therapies available, written by international specialists combining experience from both academic centers and commercial industries.

ABSTRACT. A recent emerging technology, somatic cell nuclear transfer (SCNT), has been considered for conserving threatened or endangered species. Sapsaree is a native breed in Korea and has been designated as a Natural Monument. The aim of this study was to produce a Sapsaree by SCNT for breed conservation. Donor fibroblasts from a 9-year-old male Sapsaree were placed into the perivitelline spaces of enucleated in vivo matured oocytes and fused electrically. A total of 309 cloned embryos were transferred into the oviducts of 15 naturally synchronized recipients. Two recipients were diagnosed as pregnant, and each delivered one cloned puppy, both of which weighed 530 g. Overall, this study demonstrated that an endangered canine breed can be conserved by SCNT.
