The effect of the Albutrisan-NR substrate on the differentiation of the primary brain culture of aging rats and on the culture of the rabbit vibrissa dermal papilla was studied. The substance is a hydrolysate of fish tissue with a molecular weight of up to 5 kDa. It was found that adding 2% of the substance to the culture medium stimulates the growth and differentiation processes in rat brain cells. The possibility of using the substance as a growth factor for 3D cultivation of pluripotent dermal papilla cells and maintaining an uncommitted state was demonstrated. The use of Albutrisan-NR as a trophic factor in neuronal induction of dermal papilla cells was also shown.
