Abstract: The invention relates to the field of biology and, in particular, to the field of cellular biology. The invention concerns a novel glucose-sensitive cell line designated .beta. cell line (INS-I) expressing glucokinase and the glucose carrier Glut 2 at levels comparable with those of normal .beta. cells but which is, in addition, incapable of IGF-II expression-dependent proliferation because of genetic manipulation. The invention also concerns a method for the production of said novel cell line, its aggregation in the form of a pseudoislet, its immobilization in a biocompatible hydrogel and its hardening by means of a hardening solution. Application in insulin-secreting .beta.-cell transplants.
