In the field of regenerative medicine, regeneration of cartilage defects (caused either by injury or age-related degeneration) has become a widely discussed topic. Nanofibrous scaffolds provide a suitable environment for cell adhesion, proliferation, differentiation, and also for the local involvement of bioactive substances. Nanofibrous scaffolds mimic the extracellular matrix (ECM) of hyaline cartilage. These scaffolds are seeded with autologous chondrocytes. After having been isolated from the patient, the cells must be cultivated in vitro in order to obtain a sufficient amount of chondrocytes. Scaffolds with cultivated chondrocytes are later implanted back into the pacient. Chondrocytes, however, when grown on a 2D tissue culture plastic rapidly de-differentiate and thus lose the ability to synthesize ECM molecules. The aim of the work was modulation of chondrogenic differentiation medium through finding the ideal concentration of chondrogenic supplements, composed of L-ascorbate-2-phosphate (A2P) and dexamethasone (DEX), in the culture of primary chondrocytes seeded on a nanofibrous polycaprolactone (PCL) scaffold. The effect of different concentrations of the chondrogenic supplements on chondrocyte adhesion to the scaffold and their proliferation and differentiation was studied. The influence...
