Abstract:

Articular cartilage (AC) cannot repair itself due to the lack of blood vessels, nerves and lymph, To some extent, exogenous cell-based treatment strategies can regenerate articular cartilage, however, there were some risks such as long surgical interval, limited donor availability, easy cell dedifferentiation in vitro and pathogen transmission. When cartilage is damaged, many kinds of stem cells/progenitor cells (SCPCs) in adult knee joints will be mobilized and migrated to damaged area and participate in regeneration repair. Therefore, based on recruitment endogenous SCPCs, the in-situ AC regeneration strategy has become a research hotspot, which fully utilizes the body's self-repair potential and avoids the disadvantages of exogenous cell strategy. The characteristics and migration pathway of different SCPCs in the knee joint and its role in the repair of cartilage injury were introduced. At the same time, progress of endogenous AC regeneration and repair strategies were mainly focused, in order to attract more researchers to participate in this promising research field.

Key words: Knee joint, Cartilage injury, Stem cells, Progenitor cells, Regeneration
