Washington D.C., June 20: Researchers developed a new drug delivery system with the help of curcumin, the main ingredient in the spice turmeric, that successfully prevents bone cancer cells to spread and promote the growth of healthy bone cells. The work could lead to better postoperative treatments for people with osteosarcoma, the second most prevalent cause of cancer death in children, reported the Journal of Applied Materials and Interfaces. Turmeric Health Benefits: Fighting Cancer, Preventing Diabetes and Other Reasons Why You Should Have This Curcumin-Rich Spice.

Young patients with bone cancer are often treated with high doses of chemotherapy before and after surgery, many of which have harmful side effects. Researchers would like to develop gentler treatment options, especially after surgery when patients are trying to recover from bone damage at the same time that they are taking harsh drugs to suppress tumour growth.

Turmeric has been used in cooking and as medicine for centuries in Asian countries, and its active ingredient, curcumin has been shown to have anti-oxidant, anti-inflammatory and bone-building capabilities. It has also been shown to prevent various forms of cancers.

"I want people to know the beneficial effects of these natural compounds. derived from these plant-based products are inexpensive and a safer alternative to synthetic drugs," said Bose.

However, when taken orally as medicine, the compound can't be absorbed well in the body. It is metabolized and eliminated too quickly. In their study, the researchers used 3D printing to build support scaffolds out of calcium phosphate. While most implants are currently made of metal, such as ceramic scaffolds, which are more like real bone, could someday be used as a graft material after bone cancer surgery.

The researchers incorporated curcumin, encapsulated in a vesicle of fat molecules into the scaffolds, allowing for the gradual release of the chemical.The researchers found that their system inhibited the growth of osteosarcoma cells by 96 per cent after 11 days as compared to untreated samples. The active ingredient curcumin present in turmeric is also a powerful antioxidant long known to have anti-carcinogenic properties.

The system also promoted healthy bone cell growth."This study introduces a new era of integration where modern 3d printing technology is coupled with the safe and effective use of alternative medicine, which may provide a better tool for bone tissue engineering," said Bose.
