    ..Comparing WUS function in stem cell maintenance and sexual organ development suggests that WUS expressing cells represent a conserved signaling module that regulates behavior and communication of undifferentiated cells. ..
  9. Jumaa H, Mitterer M, Reth M, Nielsen P. The absence of SLP65 and Btk blocks B cell development at the preB cell receptor-positive stage. Eur J Immunol. 2001;31:2164-9 pubmed
    ..Together, the data demonstrate the synergistic role of SLP65 and Btk in B cell development and describe a situation where large numbers of preB cell receptor-positive cells accumulate in the bone marrow and spleen. ..
