To evaluate the in vitro effects of hyaluronic acid (HA) on adipose-derived stem cells (ASC) in order to consider the possibility of their combined used in the treatment of knee arthrosis. The ASC cells were grown both in the presence and absence of AH, and several studies were carried out: proliferation (WST8) and cell viability studies (Alamar Blue and Trypan Blue), possible chondrogenic differentiation (collagen type 2 expression) by RT-PCR, AH receptor expression (CD44) by flow cytometry and RT-QPCR, and expression of inflammatory and anti-inflammatory factors (IL-6, TGFß, IL-10) by RT-QPCR.Objectives
