Horse stem cells boon for man
Mumbai Mirror Bureau
For the first time ever, Canadian researchers from the University of Montreal have generated pluripotent stem cells from horses.The term pluripotency refers to the ability of a stem cell to become any of the vast number of different cell types found in the body.
The findings will help enable new stem cell based regenerative therapies in veterinary medicine, and because horses’ muscle and tendon systems are similar to our own, the development of preclinical models aid to human applications.
These induced pluripotent stem (iPS) cells can develop into most other cell types and are a source of great hope for use in regenerative medicine and the development of new drugs to prevent and treat various illnesses.
The research represents a breakthrough for both human and animal health alike.“Equine iPS cells bring new therapeutic potential to the veterinary field, and open up the opportunity to validate stem-cell based therapies before clinical studies in humans,” said Kristina Nagy, research associate in the Nagy laboratory and lead author of the study.
“As well, stem-cell based studies using the horse as a model more closely replicate human illnesses, when compared with studies in mice.”
After two months of reprogramming equine somatic cells, the resulting iPS cell lines expressed hallmark markers of pluripotency, contained a correct set of horse chromosomes, and were able to form a full spectrum of cell types and tissues fulfilling the criteria of pluripotency.
“This means that the cell lines passed all the tests available to us for determining if they truly are what we think they are: pluripotent and a good source for future regenerative applications,” said Nagy.
“The horse is an excellent model for a range of human degenerative diseases, especially those involving joints, bones, tendons and ligaments, such as arthritis,” said Sheila Laverty, a professor in the Faculty of Veterinary Medicine at the University of Montreal.
“Bone fracture, as well as damaged cartilage, tendons and ligaments heal poorly in horses. Therefore, the use of iPS cells in these animals may help enhance long-term tissue repair.” Further research will be required to develop clinical treatments. The study has been published in the journal Stem Cell Reviews and Reports.
