  Bardeen regular black hole is commonly considered as a solution of general
relativity coupled to a nonlinear electrodynamics. In this paper, it is shown
that the Bardeen solution may be interpreted as a quantum-corrected
Schwarzschild black hole. This new interpretation is obtained by means of a
generalized uncertainty principle applied to the Hawking temperature. Moreover,
using the regular black hole of Bardeen, it is possible to evaluate the quantum
gravity parameter of the generalized uncertainty principle or, assuming the
recent upper bounds for such a parameter, to verify an enormous discrepancy
between a cosmological constant and that measured by recent cosmological
observations $(\sim 10^{120})$.
