Probing Regenerative Potential of Moringa oleifera Aqueous Extracts Using In vitro Cellular Assays

Background

Molecules stimulating regeneration and proliferation of cells are of significance in combating ailments caused due to tissue injury, inflammation, and degenerative disorders. Moringa oleifera is one of the most valued food plants having the profile of important nutrients and impressive range of medicinal uses.

Objective

To evaluate the potential of M. oleifera aqueous leaf and flower extracts to promote the proliferation of cells and explore their effect on cancer cell lines for assessment of safety.

Materials and Methods

Aqueous leaf and flower extracts of M. oleifera were investigated for effect on rat-derived primary fibroblast, mesenchymal stem cells (MSCs), and cancer cell lines using cell proliferation assay. They were also tested and compared for wound healing, angiogenesis, and hepatoprotective effect using in vitro assays.

Results

Statistically significant increase in the proliferation of primary rat fibroblast, MSCs, and angiogenesis was observed after treatment with aqueous flower extract. The aqueous leaf extract determined a comparatively moderate increment in the proliferation of MSCs and angiogenesis. It however showed prominent cytotoxicity to cancer cell lines and a significant hepatoprotective effect.

Conclusion

A very clear difference in response of the two extracts to different types of cells was detected in this study. The aqueous flower extract exhibited a higher potential to stimulate cell proliferation while not exerting the same effect on cancer cell lines. The leaf extract on the other hand, had a prominent antitumor and hepatoptotective effects.
