FIG 7. XHex can induce the expression of cerberus. The interre- lationship between XHex and cerberus expression was assayed by the injection of synthetic mRNA encoding either XHex (10, 100, 250 pg) or Cerberus (10, 100, 250 pg) into each ventral blastomere at the 4-cell stage, similar to the experimental design of Fig. 4. At stage 10.5, ventral endoderm tissue was explanted and assayed by RT-PCR for the expression of the other gene. XHex can induce cerberus, but Cerberus cannot induce XHex at the doses tested. Stage 10.5 whole-embryo (WE) controls of cDNA with or without reverse transcriptase (+RT, -RT) are shown. Image published in: Zorn AM et al. (1999) Copyright © 1999.
