Abstract

In the past few decades, attention and research in the field of stem cell are progressing very rapidly. Hospitals in Indonesia have been using stem cells as an alternative to cure some illnesses like diabetes, heart disease, fractures and joints, dental implants, and asthma. The purpose of this research was to characterized and to produced stem cells from human subcutaneous adipose tissue (ADSC), which can be used for assessing cytotoxicity effects potency of Zingiber officinale (red ginger), Curcuma aeruginosa (temu ireng) and Curcuma xanthorhiza (temulawak) on ADSC proliferation. The cytotoxic effect was done using MTT assay. The results showed Z. officinale var. and C. xanthorhiza Roxb. extracts have no cytotoxic effect to ADSC at 25 ppm, 50 ppm and 100 ppm concentrations, however the proliferation inhibition of Z. officinale extracts gradually rises to 0.05 % at 200 ppm and slightly fall at 600 ppm, after that it sharply raises unto 74.84% at 1000 ppm. The proliferation inhibition of C. xanthorhiza extracts at 200 ppm is about 28% and significantly increase to 90 % at 1000 ppm which is the highest percentage on the figure. The C. aeruginosa extracts has no inhibition effect to ADSC from 25 ppm until 800 ppm concentration of extract, however it modestly goes up at 1000 ppm reaching 9% of inhibition. Further studies are required to investigate the metabolites in these extracts that are highly correlated with its toxic effects.
