Estimating the term…
The invention relates to a method for reducing the viscosity of a nanofibrillar cellulose hydrogel, wherein the method comprises mixing a nanofibrillar cellulose hydrogel with an aqueous growth medium for cell culture, wherein the aqueous growth medium contains one or more salts and optionally one or more sugars, using shearing forces so that a homogeneous dispersion is formed. The invention further relates to a dispersion comprising a nanofibrillar cellulose hydrogel and an aqueous growth medium for cell culture and to a use of an aqueous growth medium.
A method for reducing the viscosity of a nanofibrillar cellulose hydrogel, wherein the method comprises mixing a nanofibrillar cellulose hydrogel with an aqueous growth medium for cell culture, wherein the aqueous growth medium includes one or more salts and optionally one or more sugars, using shearing forces strong enough in order to disperse the nanofibrillar cellulose homogeneously in the mixture so that a homogeneous dispersion of the nanofibrillar cellulose is formed, wherein individual rafts of hydrogel are not observable visually or macroscopically in the homogeneous dispersion, the nanofibrillar cellulose hydrogel comprising about 0.05%-4% (w/w) of nanofibrillar cellulose.
A dispersion comprising a nanofibrillar cellulose hydrogel and an aqueous growth medium for cell culture, wherein the aqueous growth medium includes one or more salts and optionally one or more sugars, and wherein the nanofibrillar cellulose hydrogel is homogeneously dispersed in the aqueous growth medium and wherein individual rafts of hydrogel are not observable visually or macroscopically, wherein the dispersion comprises about 0.05%-2.5% (w/w) of nanofibrillar cellulose.
