Permanence of the cell-to-cell transmission of insulin induced hormonal imprinting.
When insulin-treated (imprinted) Chang liver cell cultures were mixed with cultures which did not receive insulin treatment the information of imprinting was transmitted to the cultures which were not in direct contact with insulin. The ability of the cells to transmit imprinting was long lasting and could be detected even after four weeks, when it was nearly of the same degree as at the first measurement. Difference was found between the binding capacity of the receptors of the plasma membrane and those of the nuclear membrane.
