Pregnant Human Myometrial 1-41 Cell Viability Test on Vitamin D Administration

Abstract

Background: Preterm labor is one of the universal causes of perinatal mortality worldwide. One of the causes of preterm labor is uterine muscle integrity problems. Some mechanistic studies show insight into  vitamin D activity’s possible role in the injured muscle. This study aimed to determine whether vitamin D can increase muscle cell viability.

Methods: This experimental research used human smooth muscle uterine myometrium cell line PHM1-41. The cells were cultured for 24 hours in hypoxia condition, then incubated with several doses of vitamin D. The PHM1-41 cell viability was measured using spectrophotometry.

Results: The result showed that the minimum level of muscle cell viability after vitamin D incubation was with 300nM administration, and the maximum level was after 10nM (88.57%+4.48 and 96.21%+2.13 respectively).

Conclusions: Vitamin D at a specific dose could improve cell availability. The optimal dose to improve cell viability was 10nM.
