title: Coordinate expression of beta1 integrins and their regulator, TGF beta2 at the floor plate of the medulla oblongata is correlated with the crossing of the fibers of olivocerebellar projection in mice.
abstract: During embryonic day 11 (E11) to E16, contact-dependent interacting molecules beta1 integrins and their putative regulator TGF beta2 are coordinately expressed at the floor plate in the caudal part of mouse myelencephalon. Their expression disappears at E18. Consistent with the peak of their expression (E13-E16), olivocerebellar fibers primarily cross the floor plate. These data indicate that spatiotemporal expression of beta1 integrins and TGF beta2 is correlated with the crossing of olivocerebellar fibers.
