This article talks about a fairly new procedure being used on dogs and cats which helps them sort of defeat natural aging. This procedure includes use of stem cells and implantation into injured or deteriorating parts of the animals. This procedure, though costly, has improved the quality of life for many animals and shows a quick turn around for improved life. So far it has been used on ligament and joint deterioration problems, broken body parts, etc. and has led to a more sustainable happy life in the pets.
This article is interesting for it considers other aging than just human. Honestly, I feel that this could lead to a procedure such as this being developed for humans which just more increases the implications of medicine shaping the way we live and age. Though this article is vague in the actual procedure it is interesting that there is a procedure out there making changes such as these. I imagine there are some ethical considerations due to the use of stem cells, but it could be an interesting addition to the human medical field someday as it is making strides in the veterinary world today.
