Kartogenin
Based on 32 publication(s) in Google Scholar
Kartogenin (KGN) is an inducer of chondrogenic tissue formation (EC50: 100 nM). Kartogenin induces chondrogenesis by binding to fibrin A, disrupting its interaction with the transcription factor core binding factor beta subunit (CBFβ), and by modulating the CBFβ-RUNX1 transcriptional program. Kartogenin also promotes tendon-bone junction (TBJ) wound healing by stimulating collagen synthesis. Kartogenin is widely used in cell-free therapy in the field of regeneration for cartilage regeneration and protection, tendon-bone healing, wound healing and limb development. Kartogenin promotes cartilage repair, coordinates limb development, and is also used in osteoarthritis (OA) research.

Protocolo
Rabbit BMSCs or PTSCs are treated with various concentrations (1 nM to 5 μM) of kartogenin. The medium is changed every 3 days and after 2 weeks, cell proliferation is measured by population doubling time[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Rats: Then rats are divided into two groups based on the injections received: six rats are given 10 µL saline injections in each wound (wound-only group) and six rats receive 10 µL of 100 µM kartogenin solution each in the wounded areas (wound+kartogenin group). The injections are given immediately after wounding and repeated on days 2, 4, 7 and 12[1].
