Nano-nutrition of chicken embryos. Effect of gold and taurine nanoparticles on muscle development

The objective of present experiment was to reveal influence of taurine, nanoparticles of gold or nanoparticles of gold conjugated with taurine on molecular and morphological status of muscle’s fibre proliferation activity at the end of embryogenesis. The expression of Proliferating Cell Nuclear Antigen (PCNA) was determined in embryonic chicken pectoral muscle using real time PCR and immunohistochemical method. Furthermore, we calculated the average number of nuclei within the muscle fibre fasciculus in cross sectional image. Taurine, supplemented in ovo to chicken embryo, enhanced organization of breast muscle by activating molecular mechanisms evaluated as an expression of PCNA. Nanoparticles of gold did not influence examined parameters.
