The effect of Pax6b on the number of EEC expressing pyyb and mlnl does not depend on its homeodomain. FISH showing the respective increase of mlnl+ EECs and decrease of pyyb+ EECs in the pax6bsa0086 null mutants (b, e), while the hypomorphic pax6bsunrise mutants harbouring a mutation in pax6b homeobox do not display modifications in the expression of EEC hormones (c, f)
