WNT4 expressions in different cell types. Human WNT4 gene expression (indicated by a 160 bp RT-PCR product) was seen in human embryonic kidney HEK293T cells; both tammar primary lung cells and kidney cells express the tammar WNT4 gene (indicated by a 102 bp RT-PCR product). Gel lanes are marked as follows: M, Marker; 1,5, Negative Control; 2, HEK293T cDNA; 3, tammar lung cell cDNA; 4, tammar kidney cell cDNA.
