Ellinor Spörndly-Nees
My name is Ellinor Spörndly-Nees, I am a veterinary and a researcher. I am interested in anatomy and are doing research in the area of reproduction, functional anatomy and environmental chemicals. I have both worked with horses, polar bears, rats and mink in my research.
Presentation
Presentation: Currently I am working as a post-doctoral researcher at the department of Anatomy Physiology and Biochemistry at SLU. I graduated as a veterinarian at the Faculty of Life Science in Denmark, 2008. After my graduation, I worked with small animals at veterinary clinics in Enköping and in Lund. I received my PhD at SLU November 2018.

Current research
No hoof no horse:
Right now, I am working as a post doctor in a project investigating hoof quality in Standardbred trotters. Our research group has shown that Standardbred trotters run faster without shoes. However, some horses do not have strong enough hoof to run barefoot which can result in sore hoofs after races, which is a welfare problem. We aim to find out why some horses can compete barefoot and some can´t. We also want to find robust measures, for the trainers to use before a race, which can evaluate hoof quality to help predicting if the horse will be able to compete barefoot.
Hoofs from two groups of horses are collected. "Barfoot horses", that competed frequently barefoot and "Shoe horses", that not compete barefoot and raced with shoes due to poor hoof quality. We investigate the difference between the groups by measureing angels, hardness of the hoofs, conductivity and chemical properties. We also take samples from the hoofs to study the cells in details in microscope and investigate gene expression.
The project will lead to a better knowledge in hoof quality in Standard breed horses.

Finally, we investigated how environmental chemicals effected the reproduction of male Polar bear. The Polar bear organs are collected in Greenland. International collaborator in the projects are Christian Sonne from the Department of Bioscience - Artic Research Center, Roskilde, Denmark

Other research
Environmental chemicals and reproduction:
During the last decades, there has been a growing concern for the increased frequency of reproductive disturbances in both animals and humans. Chemicals in the environment disrupting the action of reproductive hormones seems to be part of the explanation. To detect adverse effects on male reproduction, histopathology of testicular tissue is considered to be the most sensitive tool. Subtle changes in cells in testis might lead to infertility. During my PhD, I worked with finding good robust methods to detect alteration in the male reproductive organs by using different staining techniques as well as image analyze. I studied both rat, a frequently used laboratory animal and wild animals, such as mink and polar bear, to find out how chemicals in our immediate environment affect male reproduction.
During the first project, we investigated how to best collect samples from wild animals to be able to separate damage due to inadequate sampling from damage due to disturbed reproduction. We also developed a novel computerized method to analyze testicular tissue from Mink. This project was a collaboration with the Center of Image Analysis at Uppsala University.
We also investigated the effect of Bisphenol A on male reproduction when the rats were exposed at environmental relevant doses BPA during pregnancy. This project is a collaboration with scientists at the Department of Medical
