Holomorphic fiber bundle with Stein base and Stein fibers

In this article, we prove that if $\mathrm{\Pi }:X\to \mathrm{\Omega }$ is a surjective holomorphic map, with $\mathrm{\Omega }$ a Stein space and $X$ a complex manifold of dimension $n\ge 3,$ and if, for every $x\in \mathrm{\Omega }$ there exists an open neighborhood $U$ such that ${\mathrm{\Pi }}^{-1}(U)$ is Stein, then $X$ is Stein
