ผ๋ฌธ (์์ฌ)-- ์์ธ๋ํ๊ต ๋ํ์ ์น์ํ๋ํ์ ์น์๊ณผํ๊ณผ, 2017. 8. ์ ํํ.Purpose : Calcitonin is a natural hormone controlling calcium metabolism by decreasing blood calcium ion level and storing calcium deposit in bone. Dental stem cells have been studied in regenerative medicine because of its multi-lineage differentiation potential. The purpose of this study is to determine the effects of calcitonin on human periodontal ligament stem cells (hPDLSCs).
Materials and Methods : After primary culture of hPDLSCs from extracted third molar, FACS, Alizarin red S staining, Alcian blue staining, and Oil red O staining were done to confirm stem cell origin and multilineage differentiation potential. Effects of calcitonin on proliferation, migration, and differentiation of hPDLSCs were evaluated with CCK-8 assay, wound healing assay, ALP
staining, Alizarin red S staining, and real-time PCR analysis.
Results : Cultured human PDLSCs were confirmed of its
mesenchymal stem cell-like properties with osteogenic,
chondrogenic, and adipogenic differentiation potential. No significant cytotoxicity was observed after 24 and 48 hours, and cell proliferation increased mostly with 1 nM calcitonin at 48 hours. Under the same concentration, cell migration and expression of osteogenic differentiation markers increased the most.
Conclusion : From this study, treatment with 1 nM
calcitonin promotes osteogenic differentiation, cell proliferation and migration of hPDLSCs. These results support the idea that calcitonin could be used not only in treatment of osteoporosis and hypercalcemia but also in the field of regenerative medicine.I.

The purpose of this paper is to explore the effects of public transfer income to long-term recipients of the national basic livelihood security system on work and private transfer income using simultaneous equation models. This study did not find, however, that public transfers statistically impact income from labor and private transfers, which was generally accepted in previous studies. One reason is that a lot of long-term recipients are elderly people lacking labor ability. Another is that private transfer supports recipients receive from family members are very low, which is not likely to change. These results are difficult to explain with classical economics. Thus, on the basis of the results of this study, more increases in public transfers are needed than more labor income or private transfers in order to help long-term recipients exit poverty
