Wharton's Jelly is a gelatinous substance found in the umbilical cord. It surrounds the blood vessels in the umbilical cord and provides cushioning and structural support. Wharton's Jelly is rich in mesenchymal stem cells (MSCs), which are multipotent cells capable of differentiating into various types of tissues, including cartilage, bone, and connective tissue. This makes Wharton's Jelly a valuable source of stem cells for regenerative medicine.

Exosomes are small extracellular vesicles (30-150 nanometers) secreted by many cell types, including stem cells. They play a crucial role in intercellular communication by transferring proteins, lipids, RNAs, and other molecules between cells. In the context of stem cell therapy, exosomes derived from stem cells have shown promise in promoting tissue repair and reducing inflammation.
