In recent years, regenerative medicine has revolutionized companion animal care, particularly for dogs and cats.
Rather than simply managing symptoms, veterinarians are now using cutting-edge therapies like stem cells and exosomes to repair, restore, and regenerate damaged tissues.
From degenerative joint disease to slow-healing wounds and even cancer, these cell-based therapies are unlocking new possibilities for recovery and improved quality of life.
Stem cells are undifferentiated cells with the unique ability to develop into various specialized cell types, such as muscle, bone, nerve, or blood cells.
Stem cells exert their effect by two basic mechanisms: proliferation and differentiation into local cell types, and modulation of the local environment to promote proliferation and differentiation of resident cells
They are also capable of self-renewal, meaning they can divide and produce more stem cells indefinitely
Exosomes are small extracellular vesicles (30–150 nm in size) secreted by cells, including stem cells.
They contain proteins, lipids, RNA, and microRNA that act as messengers, influencing the behavior of other cells.
Unlike stem cells, exosomes do not regenerate tissue directly.
Instead, they modulate the healing environment by reducing inflammation, stimulating cellular repair, and enhancing communication between cells.
