  Based on $e^+e^-$ annihilation data samples collected with the BESIII
detector at the BEPCII collider at 13 center of mass energies from 4.008 to
4.600 GeV, measurements of the Born cross section of $e^{+}e^{-}\rightarrow p
\bar{p} \pi^{0}$ are performed. No significant resonant structure is observed
in the measured energy-dependent cross section. The upper limit on the Born
cross section of $e^{+}e^{-}\rightarrow Y(4260) \rightarrow p \bar{p} \pi^{0}$
at the 90\% C.L. is determined to be 0.01 pb.
