  We investigate the electronic dynamics in the underdoped cuprates focusing on
the effects of one-dimensional charge stripes. We address recent experimental
Angular-Resolved Photoemission Spectra results on
(La$_{1.28}$Nd$_{0.6}$Sr$_{0.12}$)CuO$_4$. We find that various inhomogeneous
models can account for the distribution of quasiparticle weights close to
momentum ${\bf k}=(\pi,0)$ and symmetry related points. The observed flat
dispersion region around the same ${\bf k}$ point can only be addressed by
certain classes of those inhomogeneous models which locally break spin
symmetry. Homogeneous models including hopping elements up to second neighbors
cannot reproduce the experimental quasiparticle weight, since most of it is
centered around ${\bf k}=(\frac {\pi}{2},\frac {\pi} {2})$.
