![]() Consequently, there are a large number of different subtypes of ‘adult stem cells’. As mentioned earlier, these stem cells tend to be limited in their transformative capacity by being confined to change into cell types found in their local environment. Tissue-Specific Stem Cell: These stem cells are found all over our bodies, and are called ‘adult’ or ‘tissue-specific’ stem cells.While offering significant regenerative potential, there are currently a number of ethical concerns regarding the use of embryonic stem cells. Consequently, it is possible they could be more effective than ‘adult’ stem cells which do not have this capacity. ![]() ![]() They are unique because they can transform into any type of tissue or organ cell type in the human body. Embryonic Stem Cell: This type of stem cell can be found in human embryos shortly after fertilization.Cells with this characteristic are called Tissue Specific Stem Cells. If moved to a new location, they don’t always transform into the intended cell type needed for that particular tissue. To complicate things further, some stem cells are only capable of specializing into cell types present in their local environment. Reduced chondrocyte activity and volume is thought to be closely linked to osteoarthritis. Chondrocytes produce and maintain cartilage. The goal of stem cell injections for knee osteoarthritis is to increase the number and activity of these cells thereby reversing or slowing cartilage degeneration.Ĭhondrocyte: The only cell type found in healthy cartilage. When it comes to the knee joint, it is a cell type called a chondrocyte that repairs and maintains joint cartilage. Stem cells exist all over the body and act as a repair system for damaged organs or tissues where these specialized cell types are required. This means they have the ability to transform into more specialized cells when needed. Stem cells are commonly referred to as undifferentiated or unspecialized cells.
