Abstract

Cell regeneration has great significance in the field of science. Its advancement can lead to faster healing of damaged tissue in the human body. There have been many studies on au-tumerone, a compound in turmeric, that have revealed its ability to stimulate neural stem cell reproduction and generate healing properties. Every multicellular organism can regenerate to a certain extent. Humans regenerate skin cells constantly and when healing wounds. Animals like the brown planaria, Girardia tigrina have the ability to regenerate parts of their body when transected. This study was conducted to test the effect of turmeric on the regeneration rate of Girardia tigrina compared to a control group in water. During this experiment, incised planaria were exposed to various concentrations of turmeric (0%, 0.00875%, 0.0175%, and 0.025%) for 4 days. Their lengths were measured every 24 hours, and the measurements, along with the percent changes, were analyzed in single factor ANOVA tests. The data showed positive growth for overall length of the planaria in control, 0.0175%, and 0.025% groups, however no statistically significant data was found. Additional ANOVA tests were run on mean percent change from day 1-4 and statistically significant data was found between 0% and 0.00875%. The hypothesis, which stated if Girardia tigrina are treated with turmeric, then the regeneration rate will be increased was rejected. The null hypothesis that there would be no difference in tail regeneration rate between planaria treated with turmeric and the control failed to be rejected.
