We report the cloning and expression during limb development of the chicken
Slit1, Slit2, and Slit3 ligands, and Robo1 and Robo2 receptor genes. We al
so compare the expression patterns of Robo1 and Robo2 in developing chick a
nd mouse hindlimbs. These genes are expressed in regions of muscle developm
ent, chrondrogenesis, and axon guidance. (C) 2001 Elsevier Science Ireland
