Cellular basis of differential endochondral growth in Lake Malawi cichlids.

ABSTRACT:

Background

The shape and size of skeletal elements is determined by embryonic patterning mechanisms as well as localized growth and remodeling during post-embryonic development. Differential growth between endochondral growth plates underlies many aspects of morphological diversity in tetrapods but has not been investigated in ray-finned fishes. We examined endochondral growth rates in the craniofacial skeletons of two cichlid species from Lake Malawi that acquire species-specific morphological differences during postembryonic development and quantified cellular mechanisms underlying differential growth both within and between species.

Results

Cichlid endochondral growth rates vary greatly (50%-60%) between different growth zones within a species, between different stages fo
