Stem cells are undifferentiated cells that have the potential to develop into various types of specialized cells in the body. They are unique in their ability to self-renew and differentiate into specific cell types, making them valuable for regenerative medicine and tissue engineering. Research in the field of stem cells focuses on understanding the mechanisms that regulate their differentiation and proliferation, as well as exploring their potential applications in treating a wide range of medical conditions, such as cancer, degenerative diseases, and injuries. There are different types of stem cells, including embryonic stem cells, adult stem cells, and induced pluripotent stem cells, each with their own distinct properties and capabilities. The field of stem cell research holds great promise for developing innovative therapies and treatments for a variety of diseases and conditions.
