Effects of the loss of transmembrane adaptor protein WBP1L on bone marrow transplantation efficiency in mouse analyzed using RNA-Seq

Murine WBP1L-deficient (Wbp1l-/-) hematopoietic stem and progenitor cells engraft significantly better than wild-type (WT) cells in competitive transplantation assays. To analyze the mechanism, Wbp1l-/- or WT bone marrow cells (both Ly5.2+Ly5.1-) were each mixed 1:1 with WT competitor cells (Ly5.2+Ly5.1+) and the mixture was transplanted into the lethally irradiated recipient mice. 22 weeks after the transplantation the donor Ly5.2+Ly5.1- LSK cells (Wbp1l-/- or WT) were purified from the bone marrow of recipient mice, RNA was extracted and subjected to RNA sequencing.
