ABSTRACT
Objective: To investigate the effects of adipose-derived mesenchymal stem cells (ADMSCs) on proliferation and hormone secretion of parathyroid cells in votro. Methods: The parathyroid cells and ADMSCs were obtained from 10 SD rats by cell separation and culture. The phenotype of P3 generation for ADMSCs was detected by flow cytometry. The co-culture of parathyroid cells and ADMSCs was conducted in the ratios of 2∶1, 1∶1, 1∶2 and 1∶5, respectively. The level of parathyroid hormone in cell supernatant was determined. The results were compared with the parathyroid hormone in the supernatant of parathyroid cells cultured separately in the corresponding number. The effects of ADMSCs on the hormone secretion of parathyroid cells were evaluated. SPSS 11.0 software was used for statistical analysis . Results: The primary culture of either parathyroid cells or ADMSCs and the co-culture of these cells in vitro were performed successfully, and the in vitro culture of different proportions of the two cells showed different effects on parathyroid hormone secretion. The co-culture of parathyroid cells and ADMSCs, especially in the ratio of 1∶5, facilitated the secretion of parathyroid hormone ((1.3±0.0) vs. (0.8±0.1), (1.3±0.0) vs. (0.9±0.0), (1.7±0.5) vs. (0.9±0.0), (1.7±0.0) vs. (1.2±0.2))ng/L with t value of 25.46, 64.30, 3.32, 7.16, P<0.05 on the 2nd, 4th, 6th and 8th days respectively. Secondly, when the ratio was 1∶2, the PTH level showed an upward trend. Conclusion: Parathyroid cells and ADMSCs can be co-cultured in vitro, facilitating the secretion of parathyroid hormone under the appropriate cell proportion such as the ratio of by parathyroid cells to ADMSCs at 1∶5.
