Expression of HDGF family members in different brain regions. Tissue homogenates of different rat brain regions were prepared as described under material and methods and subjected to Western blot analysis with antibodies against the proteins listed. Brain regions examined were as indicated above the figure. The Coomassie stained PVDF membrane is shown underneath the figure to demonstrate equal loading for the different brain regions. Molecular weights of marker proteins in kiloDalton are given on the right side of the figure.
