Induction of superficial zone protein (SZP)/lubricin/PRG 4 in muscle-derived mesenchymal stem/progenitor cells by transforming growth factor-β1 and bone morphogenetic protein-7.

Introduction: Articular cartilage (AC) is an avascular tissue with precise polarity and organization. The three distinct zones are: surface, middle and deep. The production and accumulation of the superficial zone protein (SZP), also known as lubricin, by the surface zone is a characteristic feature of AC.

Rats fed the dietary supplement vitamix® (ceregumil® with vitamins) show greater physical resistance and antioxidant capacity.

Objective: Vitamix® is a dietary product composed of a hydro-alcoholic extract of cereals and pulses with honey, calcium glycerophosphate, vitamins B and D, selenium and fluoride. The basic product, Ceregumil®, patented in 1912, was highly popular as tonic and consumers reported a feeling of health, resistance to illness, and increased predisposition to work and exercise.

Material And Method: In the present study we analysed the effect of Vitamix® used as dietary supplement, on several physiological parameters in laboratory rats.
