Fig. 2From: Extracellular cathepsin L stimulates axonal growth in neuronsEffect of extracellular cathepsin L on the expression level of cathepsin L mRNA in cortical neurons. Cortical neurons were cultured for 3 days and then treated with vehicle solution (Cont) or cathepsin L (50 ng/ml). Cell lysates were prepared for cathepsin L mRNA quantification 4 days after treatment. The expression levels are shown as a relative ratio to the control group. n = 3 wellsBack to article page
