ENTEROCYTE GROWTH FACTORS AND METHOD FOR THEIR ISOLATION

摘要

The invention refers to 20 enterocyte growth factors - EGFs with enhanced effectiveness as to their influence on the speed of morphogenesis, 9 of them stimulate cell growth and 11 ones inhibit cell growth. The method is in isolating them from intestinal mucosa from warm-blooded animals. Mucosa can also be from large intestines from warm-blooded animals. It is possible that mucosa is both from small and large intestines from warm-blooded animals with chemical carcinogenesis, and the ratio between the inhibiting and stimulating enterocyte growth factors in biomass can vary within 6:4 to 5:5, or 5:5.001 to 4:6, or 8:2 to 7:3. The method is characterised by its higher productivity and higher resolution with regard to fractions, and allows for wider possibilities for the production of more qualitatively different EGFs.
