Expression analysis of XPhyH-like during development and tail regeneration in Xenopus tadpoles: Possible role of XPhyH-like expressing immune cells in impaired tail regenerative ability

► XPhyH-like is induced in Xenopus tadpole tail stumps during the refractory period. ► FK506-treatment suppresses XPhyH-like expression in the amputated tail stumps. ► XPhyH-like expression is enriched in the blood cell fraction. ► XPhyH-like expressing cells can be related to the impaired regenerative ability. ► XPhyH-like could be a marker gene for autoimmune cells that attacks blastema cells.
