The explosions of pregalactic stars in the period z between 10 and 1000, when Compton cooling dominates, could initiate a bootstrap process in which ever-larger shells of swept-up gas successively fragment into more exploding stars. A simple relationship between the amplifications occurring at each stage is derived and that the shells mass, in the absence of shell mergers, would tend to a characteristic value which depends only on the redshift and explosive efficiency. When radiative-cooling begins to dominate at z of roughly 10, the shells should fragment into galactic-size objects rather than stars but by then the shells could already be large enough to serve as the 'seeds' required in the Ostriker-Cowie-Ikeuchi picture. They might even be large enough to generate the filamentary structure and giant voids indicated by recent observational results, providing the shells eventually overlap.
