Introduction and objectives As tissue engineering and regenerative medicine have continued to evolve within the field of biomedicine, the fundamental importance of bio-products has become increasingly apparent. This true not only in cases where they are derived directly from the natural environment, but also when animals and plants are specially bred and cultivated for their production. Objective The study aims to present and assess the global influence and importance of selected bio-products in current regenerative medicine via a broad review of the existing literature. In particular, attention is paid to the matrices, substances and grafts created from plants and animals which could potentially be used in experimental and clinical regeneration, or in reconstructive procedures. Summary Evolving trends in agriculture are likely to play a key role in the future development of a number of systemic and local medical procedures within tissue engineering and regenerative medicine. This is in addition to the use of bio-products derived from the natural environment which are found to deliver positive results in the treatment of prospective patients.

Introduction and objective. The aim of the presented study was to check differences between ‘Diet’ and ‘non-Diet’ soft drinks on cell proliferation. Materials and methods. Coca Cola and Pepsi Cola of different origin and their dietetic versions were examined at concentrations of 2% and 4%. Fructose and glucose as well as medium alone (control) were examined. Results. Cell number was higher in media supplemented with soft drinks, compared to control. Proliferation depended on the soft drink concentration and its origin, but not on sugar and calorific content. Conclusions. An unknown factor is responsible for the increase in proliferation.
