Could the authors clarify how they accounted for potential contamination from adjacent tissues (cementum, alveolar bone) during laser capture microdissection (LCM) of the periodontal ligament? Given the high sensitivity of LC-MS/MS, even minor contamination could influence the proteomic profile. Were any controls or validation steps performed to confirm the specificity of the captured PDL tissue?
