Regeneration factors expressed on myeloid expression in macrophage-like cells is required for tail regeneration in Xenopus laevis tadpoles.

ABSTRACT: Xenopus laevis tadpoles can regenerate whole tails after amputation. We have previously reported that interleukin 11 (il11) is required for tail regeneration. In this study, we have screened for genes that support tail regeneration under Il11 signaling in a certain cell type and have identified the previously uncharacterized genes Xetrov90002578m.L and Xetrov90002579m.S [referred to hereafter as regeneration factors expressed on myeloid.L (rfem.L) and rfem.S]. Knockdown (KD) of rfem.L and rfem.S causes defects of tail regeneration, indicating that rfem.L and/or rfem.S are required for tail regeneration. Single-cell RNA sequencing (scRNA-seq) revealed that rfem.L and rfem.S are expressed in a subset of leukocytes with a macrophage-like gene expression profile. KD of colony-stimulating facto
