What are Stem Cells?


Stem cells are nondifferentiated cells (like students with an undeclared major) that can be found in nearly every organ in the body including the vessels. A few specific stem cells have been identified for retrieval each having their own special abilities.


1- Embryonic stem cells have the ability to "differentiate" or grow up into any other type of cell found in the body but are not used in mainstream regenerative medicine due to the controversy of retrieval.

2- Tissue specific stem cells are found within organs like the liver and are harder to retrieve but have the potential to grow a cloned organ.

3-Mesenchymal stem cells (MSCs) are retrieved from connective tissue such as bone marrow or chord blood and have the potential to grow into the connective tissue they are injected into such as bone, cartilage, collagen or fat. These cells are easily retrieved without controversy and used to treat many injuries, diseases, or conditions. Due to the MSCs ability to differentiate into various types of cells in the body they are often used in regenerative medicine to repair joints, rejuvenate collagen, or even restore hair growth (Han et al., 2016; Huang et al., 2020; Kim et al., 2022; Li et al., 2022; Ma et al., 2020; Shoukrie et al., 2022).


What are Exosomes?

Exosomes, also known as extracellular vesicles (EVs) are tiny vesicles secreted by cells, that send out regenerative properties. These EVs contain bioactive molecules that aid in cell-to-cell communication and tissue repair also referred to as growth factors. Exosomes are are most often retrieved from platelets, not just because of their abundance and tissue repair capabilities, but also because platelets do not contain nuclei and therefore do not carry DNA sequence but rather a cargo of growth factors that transmit to surrounding cells a repair sequence. Platelet derived exosomes (P-EVs) are most often used in regenerative medicine for joint repair and rejuvenation including hair and collagen growth (Jeyaraman et al., 2021; Tao et al., 2017; Tenchov et al., 2022).


What are the Benefits of Stem Cell & Exosome Therapy?


Stem cells or exosomes are still in the experimental stage, with limited approvals for specific uses such as joint injection but are being tested together or in isolation to treat many conditions including osteoarthritis, autoimmune diseases, heart disease, and neurodegenerative disorders. In regenerative medicine stem cells and exosomes are approved for joint injections for conditions like osteoarthritis with amazing results! More recently, exosomes have been approved for a wider therapeutic range including topical applications in skin care with or without microneedling. Plated is serum contain 1.5 trillion exosomes and is very popular at the Med Spa at Clinical Edge.


Are there any risks or side effects associated with stem cell therapy?

Multiple studies (Han et al., 2016; Huang et al., 2020; Jeyaraman et al., 2021; Kim et al., 2022; Li et al., 2022; Ma et al., 2020; Shoukrie et al., 2022) prove for the use of injectable stem cells and/or exosomes for rejuvenation of the knee. Risks depend on the type of stem cells and the procedure. At the Med Spa at Clinical Edge only MSCs cells are used along with P-EVs limiting the possibilities of abnormal tissue growth. Other potential risks include infection or allergic reactions. Approvals vary by region and condition. Some therapies are in clinical trials, while others have received limited approvals. Because both stem cell and exosome therapies are evolving fields, and research is ongoing it is important to consult with a healthcare professional for a tailored therapeutic approach for the latest information and to determine if these therapies are suitable for your specific condition.
