Stem cells, as a concept, originated as a theory in the 19th century to potentially allow certain tissues to self-renew. There are five types of stem cells, and MSC's are multi-potent, meaning they are cells that have the ability to develop into more than one type of specialized cell. Mesenchymal stem cells were originally discovered and ...
Adult stem cells, also called somatic (from Greek σωματικóς, "of the body") stem cells, are stem cells which maintain and repair the tissue in which they are found. [44] There are three known accessible sources of autologous adult stem cells in humans: Bone marrow, which requires extraction by harvesting, usually from pelvic bones via ...
Their work led to multiple patents, animal trials and subsequently, a human clinical trial of a porcine bone-patellar tendon-bone graft for reconstructing the anterior cruciate ligament (ACL) of the knee joint. In the surgical procedure, the proteins on the transplant ligament that would trigger rejection from the recipient's body are stripped ...
Most stem cells intended for regenerative therapy are generally isolated either from the patient's bone marrow or from adipose tissue. [15] [16] Mesenchymal stem cells can differentiate into the cells that make up bone, cartilage, tendons, and ligaments, as well as muscle, neural and other progenitor tissues. They have been the main type of ...

When referring to bone, or in this case cartilage, the originally undifferentiated mesenchymal stem cells lose their pluripotency, proliferate and crowd together in a dense aggregate of chondrogenic cells (cartilage) at the location of chondrification. These chondrogenic cells differentiate into so-called chondroblasts, which then synthesize ...
Techniques such as the EELS-TALC [4] to enhance ACI and its next generation advancement called Matrix Assisted Chondrocyte Implantation (MACI) [5] with enabling chondrocytes to be tissue engineered with long term native knee cartilage phenotype maintenance in vitro and in vivo, [6] [7] with the engineered tissue construct containing stem cell progenitors [8] along with those expressing ...
A stem cell possesses two properties: . Self-renewal is the ability to go through numerous cycles of cell division while still maintaining its undifferentiated state. Stem cells can replicate several times and can result in the formation of two stem cells, one stem cell more differentiated than the other, or two differentiated cells.
