What type of cell is commonly used in tissue engineering?

Mesenchymal stem cells are commonly used in tissue engineering due to their unique properties and versatility. These cells have the ability to differentiate into a variety of cell types, including bone, cartilage, and fat cells, making them particularly valuable for regenerating damaged tissues. Their potential to migrate to sites of injury and their capability of secreting bioactive molecules that can aid in tissue repair further enhance their usefulness in therapeutic applications.

Mesenchymal stem cells can be isolated from various tissues, including bone marrow, adipose tissue, and umbilical cord, providing a relatively accessible source for researchers and clinicians. Moreover, their immunomodulatory properties allow them to be used in allogeneic transplants without significant risk of rejection, which is a significant advantage in tissue engineering strategies.

While skin cells are important in certain applications, they are often not as versatile as mesenchymal stem cells for a broad range of tissue engineering needs. The choice not to use cells at all or to imply that all cells can be used without discernment does not reflect the specific requirements and advancements in tissue engineering practices that prioritize certain cell types based on their functional advantages.
