Mesenchymal stem cells (MSCs), are able to differentiate into cartilage, tendon, bone, fat, muscle, etc… They are found in many tissues in an adult individual, such as in adipose tissue, bone marrow or in the umbilical cord.

At present, other companies are currently extracting MSCs invasively, both from marrow, by sternum puncture, and from adipose tissue, removed from the base of the tail. These companies extract the cells for therapeutic purposes, at the time of the injury.

This technique has three main drawbacks:

• The quality and number of stem cells decreases with the age of the animal.

• It takes a time of 4-6 weeks of cell culture for MSCs to reach a therapeutic number.

• As a surgical procedure is involved, there is an increased risk for both the animal and the operator.
