Evidence for the presence of the tissue-specific transcription factor Pit-1 in lancelet larvae

open access: yes, 1998
Recent molecular studies have noted the affinity among cephalochordates and vertebrates. In particular, a cluster of vertebrate-like homeobox genes regulates the development of the lancelet Branchiostoma lanceolatum.

Metacercaria of trematods in the lancelet Branchiostoma lanceolatum (Pall.) of the Black Sea

open access: yes, 1966
Metacercaria of trematods were found in lancelets of the Black Sea. Morphology of the parasites found that seemed to belong to one species is described. Their genital system was not developed which gave no possibility to determine the taxonomic position ...

Molecular Searching for Gill Slits in Echinoderms: Hox1 expression in Strongylocentrotus purpuratus [PDF]

open access: yes, 2013
The formation of gill slits is a homologous trait in most deuterostomes (including hemichordates, tunicates, lancelets, and vertebrates), however is not present in the Phylum Echinodermata. Thus, there may be a difference in gene order or gene expression.
