Fig. 3From: Immunohistochemical and immunocytochemical study of mechanoreceptors in anterior cruciate ligament reconstruction with the remnant-preserving technique using Achilles tendon allograftsQuantitative RT-PCR was performed to assess the expression of nerve growth factor (NGF). Specific primers (5′-forward 5′-GTCATCATCCCATCCCATCTTC-3′, reverse 5′-CACACACAGGCCGTATCTATC-3′) were applied, and the transcription levels of GAPDH were used as a referenceBack to article page
