Mammary gland tissue distribution of PTN mRNA.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
(A) In situ hybridization (ISH) with PTN mRNA antisense and sense probes. Red squares indicate the areas shown at higher magnification. Scale Bars = 25 μm and 100 μm respectively. Red arrowheads indicate PTN mRNA expression in mammary epithelial cells. (B) Northern blot for PTN mRNA in virgin mammary glands fractionated into epithelial and stromal cells.
