Release date: 2014-04-21 Researchers at Drexel University in Philadelphia have successfully created cancer cell tumors using 3D printing technology. They say that compared to tumors cultured in two-dimensional culture dishes, the tumors are closer to natural tumors and can better help cancer and cancer medications.

1.NMN, full name Beta Nicotinamide Mononucleotide, designed to reverse the signs of aging in the body.
Our production method of NMN is Enzymatic, while purity up to 99.5%, report from third lab in US is available.
It be widely used in the market as powder, capsules and tablets. Nmn Powder,Nmn Supplements,Nmn Powder Pharmaceutical Grade,Food Grade Nmn Xi'an Natural Field Bio-Technique Co., Ltd. , https://www.naturalnf.com
It is reported that the raw materials used by the researchers are mixed glue, fibrin and cervical cancer cells (known as the Hella cells). After mixing, they are poured into a 3D cell printer, and then the printer prints the length and width of each layer. 10mm, 2mm high tumor. These tumor cells are then supplemented with nutrients and grow into spheres after 5 days.
According to the researchers, these tumors better reveal the characteristics of tumor cells, including shape, proliferation behavior, genes, and protein expression, compared to tumors in culture dishes, which can be used to test the safety and efficacy of new treatments.
The researchers also said that printing these tumors requires precise control of some parameters, so that the survival rate of cancer cells can reach 90%, otherwise, it is easy to destroy cells and cause death.
2. Function of NMN:
Nicotinamide mononucleotide(NMN) in human cells play an important role in energy generation, it involved in intracellular NAD (nicotinamide adenine dinucleotide, cell energy conversion important coenzyme) synthesis, used in anti-aging, fall blood sugar and other health care products.
