Scattergrams display the levels (mean ± SD) of collagen type I α2 mRNA as a ratio to Glyceraldehyde 3-phosphate dehydrogenase (GADPH) as measured by quantitative polymerase chain reaction of samples coincubated with morphine (MS: 10 µM), DMT-DALDA (DALDA: 10 μM), or PZM21 (10 μM), or buffer control. Each point represents a single well. One-way ANOVA was performed and a post hoc analysis was performed. Treatments linked by a common line did not differ. ***P < 0.001.
