Acetylsalicylic acid interferes with embryonic kidney growth and development by a prostaglandin-independent mechanism

Figure 2 Assessment of epithelial branching. Fetal kidneys were grown for 48 h in the presence of 0.2 mg/mL or 0.4 mg/mL ASA (n = 3 and 4 respectively; Controls n = 5). Organs were fixed and processed for laminin labelling. Upper panel shows mean number of tips counted per group. ^aP < 0.05, denotes statistical differences with control organs. Lower panel shows an example image of a control, 0.2 mg/mL or 0.4 mg/mL ASA exposed organ. ASA: Acetylsalicylic acid.
