Stem cell use in animals
Horses
Stem cell treatment has begun on horses, or mainly to treat injuries to the tendons, ligaments, and joints of sport horses or racehorses. Fat is harvested from the tail head and processed, and an animal may receive treatment within three days after the sample is taken. Injuries that may be treated include Degenerative Joint Disease, soft-tissue injuries, Osteochondrosis, fractures, and sub-chonral bone cysts. Currently, research is also being performed on stem cell application in laminitis and COPD.
Dogs
There is currently research being performed on the usefulness of stem cells (mesoangioblasts) in canine muscular dystrophy. This work, which has been successfully translated from mice to dogs could provide a means of treating muscular dystrophy in humans.
Controversy
Main article: Stem cell controversy
There is wide spread controversy over the use of embryonic stem cells. This controversy is over the technique used to create new embryonic stem cell lines, which often requires the destruction of the blastocyst.
Many groups oppose the use of human embryonic stem cells in research based on moral or religious objections. Others point to the success already being achieved with stem cell therapy that does not result in the destruction of a developing human being, such as the use of cord blood cells to treat spinal cord injury paralysis or recent research in turning skin fibroblasts into embryonic stem cell-like cells, and argue that research should be aimed in those avenues with a proven safety and efficacy.
