autologous serum, chondrocytes transplantation, vesico-ureteral reflux


Transplanted autologous chondrocytes (ACT) can be used in endoscopic treatment of vesico-ureteral reflux. Fetal bovine serum (FBS) is still a gold standard for media supplementation in many laboratories. Prion and virus diseases are a danger for patients treated with ACT if fetal bovine serum FBS is used.
The aim of this study was to establish the utility of media for chondrocytes culture supplemented with Autologous Serum (AS) or serum substitute Ultroser G (UG) instead of FBS.
material and methods
Cartilage specimens were obtained form knee joints of 5 young rabbits and digested during 10 hours with collagenase II and hyaluronidase. Autologous rabbit serum (AS) was prepared. Ham`s F-12 medium was supplemented with 10% (v/v) of FBS (Sigma) or 10% (v/v) AS. Ultroser G (UG, Gibco) was added in concentration of 2% (v/v). After 14 days living cells were counted using trypan blue.
It was not possible to obtain primary chondrocytes cultures using medium supplemented with Ultroser G. The mean total number of cells in primary cultures supplemented with 10% FBS was 5,81x106 while mean number of cells growing in medium with 10% AS was 7,27x106. Medium supplemented with AS in concentration of 10% shown the best proliferation effect on chondrocytes cultures (PRCC). There were no differences in cells morphology between cells growing in medium supplemented with 10% FBS and 10% AS.
Our preliminary results confirm the possibility of using autologous serum (AS) for establishing the primary chondrocytes cultures.
