Summary

Human skin epithelial-like cells (NCTC strain 2544) were grown in NCTC 135 medium. Neuraminidase and hyaluronidase were added to the growth medium. Cells were incubated 96 h at 36° C. Growth rate and viscosity of cell suspensions were measured after forming single cells mechanically (mopping). With addition of neuraminidase and hyaluronidase, respectively, the growth rate remains unchanged. With neuraminidase a distinct raise in viscosity was achieved, whereas with hyaluronidase only a small effect was seen. The characteristic structure viscosity is maintained in all forms of the viscosity curves at different shearrates.

Zusammenfassung

Wachstum und Viskosität menschlicher Hautepithelzellen (NCTC Stamm 2544) wurde unter Zusatz von Neuraminidase und Hyaluronidase nach 96 h Inkubation bei 37° C untersucht. Nach mechanischer Vereinzelung (mopping) der Gewebekulturzellen wurden Dichte- und Viskositätsmessungen an den Zellsuspensionen durchgeführt. Bei Zusatz sowohl von Neuraminidase als auch von Hyaluronidase wurde das Zellwachstum nicht beeinflußt. Die Zellen, die mit unterschiedlichen Mengen Neuraminidase gewachsen waren, zeigten eine deutliche Erhöhung der Viskosität, während mit Hyaluronidase nur eine geringe Wirkung erzielt wurde. Nach dem Kurvenverlauf der Viskositäten bei verschiedenen Scherraten ist hierbei die typische Strukturviskosität erhalten geblieben.
