Creative Bioarray provides various human and animal cell lines that are invaluable for medical, scientific and pharmaceutical institutions. Creative Bioarray offers Kidney Tumor Cells for your research.

It's not quite Cyclops, the sci-fi superhero from the X-Men franchise whose eyes produce destructive blasts of light, but for the first time a laser has been created using a biological cell. The human kidney cell that was used to make the laser survived the experience. In future such "living lasers" might be created inside live animals, which could potentially allow internal tissues to be imaged in unprecedented detail. It's not the first unconventional laser. Other attempts include lasers made of Jell-O and powered by nuclear reactors (see box below). But how do you go about giving a living cell this bizarre ability? Typically, a laser consists of two mirrors on either side of a gain medium - a material whose structural properties allow it to amplify light. A source of energy such as a flash tube or electrical discharge excites the atoms in the gain medium, releasing photons. Normally, these would shoot out in random directions, as in the broad beam of a flashlight, but a laser uses mirrors on either end of the gain medium to create a directed beam. As photons bounce back and forth between the mirrors, repeatedly passing through the gain medium, they stimulate other atoms to release photons of exactly the same wavelength, phase and direction. Eventually, a concentrated single-frequency beam of light erupts through one of the mirrors as laser light.

The PROOF (Prevention of Organ Failure) Centre is a not-for-profit organization that develops and implements blood-based biomarker tests to better manage patients with heart, lung and kidney failure and prevent disease progression. By embracing a cross-disciplinary team of people and uniting organizations including commercial partners, we can speed up the development of these tests, applying them sooner to improve and save lives.

"100,000 skin samples every year (that's 5 square meters of skin or a full cow's-worth annually) at its lab in Lyon. Currently, the company receives bits of donor skin from plastic surgery procedures. Then L'Oreal breaks the samples down into individual cells, re-cultures and grows them into .5 cm testing squares. The whole process takes about a week to complete but could soon be done much faster thanks to Organovo's NovoGen Bioprinting Platform. ... The bioprinter has already partnered with Merk to create liver and kidney tissues"
