Chondrocyte condensation and differentiation but not early patterning is affected by loxl3b knockdown. A-L: In situ hybridization for various genes implicated in chondrogenesis at the indicated time points. Embryos were injected with either 2 ng P53MO (A, C, E, G, I, K) or 4 ng MO2 and 2 ng P53MO (B, D, F, H, J, L) morpholino. m: mandibular; h: hyoid; b: branchial; cb: ceratobranchial arches; black arrow: hyoid condensation.
