Abstract | Aim: The tissue-engineered mandibular condylar cartilage (MCC) should ideally mimic the native zonal structure to
achieve a functional condylar replacement. This study attempted to optimize a working protocol for isolating
homogenous cell populations from MCC by using laser capture micro-dissection (LCM) technique. Methods: Frozen
sections were prepared after harvesting MCC tissues from three SD rats. Cells from four identified zones were
separately isolated (10 samples/zone) using LCM technique. tRNA was extracted for qPCR, and 3'/M ratio of GAPDH
was calculated to evaluate RNA quality. Results: The morphology of tissue sections was preserved allowing
accurate identification of all four zones of MCC, namely fibrous, proliferative, mature and hypertrophic chondrocytes
zones. This improved morphology extended the range of cell types isolated via LCM technique. The average of the
3'/M GAPDH ratios, a better guide to RNA quality for small-quantity LCM-samples, was 1.46±0.41, 1.49±0.27,
1.75±0.50, and 1.60±0.43 for fibrous, proliferative, mature, and hypertrophic samples, respectively. Conclusion: The
present study shows that the optimized LCM protocol could allow isolation of homogenous cells from various zones of
MCC separately, thereby generating accurate molecular and genetic data for further study on tissue-engineered
mandibular condylar cartilage. |
