A new “lab-on-a-chip” can examine thousands of individual live cells over a weeklong period, performing experiments that would take more than 1 million steps in a laboratory.

The credit-card-sized, microfluidic device not only saves time and money, but also offers a new glimpse into how single stem cells react to different molecules and environments.

When researchers examined neural stem cells on the device and analyzed the data, they found several new rules that determine the timing and signaling sequences necessary for the cells to differentiate or renew themselves. The finding could have implications in understanding brain development or in treating patients with immunotherapy.

Stem Cell dental implants grow new teeth in 2 months

Apparently, the newest scientific discovery can possibly leave dentures and implants in the past, and make millions of people extremely happy.

These two methods for a missing tooth or teeth can lead to serious dental health issues, such as discomfort and irritations, difficulties to eat, and pain in the case of dentures, while implants can cause infections, nerve damage, injury or damage to the surrounding structures, and sinus problems.

Robots grow mini-organs from human stem cells

An automated system that uses robots has been designed to rapidly produce human mini-organs derived from stem cells. Researchers at the University of Washington School of Medicine in Seattle developed the new system.

The advance promises to greatly expand the use of mini-organs in basic research and drug discovery, according to Benjamin Freedman, assistant professor of medicine, Division of Nephrology, at the UW School of Medicine, who led the research effort.

Robots can grow humanoid mini-organs from stem cells faster and better than people

Automated robots now have the tools to grow imitation, simplified human organs out of stem cells. Thankfully, we weren’t transported to a sci-fi dystopia where the machines have risen up and started to farm humans, but rather a world where pharmaceutical and other biomedical research just became much easier and faster.

Give these robots some pluripotent stem cells (stem cells that can become any type of cell), and 21 days later they’ll have finished a complicated experiment testing out the effects of a drug or genetic manipulation on some human-like, lab-grown kidneys. According to research published yesterday, May 17, in Cell: Stem Cell, the process is much faster and more reliable than when humans grow the same mini-organs.

Japan approves first trials of stem cell-based heart treatment

iPS procedure raises hopes for alternative to donations and artificial organs

TOKYO — Japan is set to host the world’s first clinical trials involving the use of induced pluripotent stem (iPS) cells to treat heart failure.

A special health ministry panel on Wednesday gave Osaka University the green light to carry out the study, pending final authorization from the health minister. This would be the second instance of using iPS-derived cells for disease treatment in Japan, after groundbreaking trials involving retinal cells launched in 2014.

Scientists grow full sized, beating human hearts from stem cells

It’s the closest we’ve come to growing transplantable hearts in the lab

Of the 4,000 Americans waiting for heart transplants, only 2,500 will receive new hearts in the next year. Even for those lucky enough to get a transplant, the biggest risk is the their bodies will reject the new heart and launch a massive immune reaction against the foreign cells. To combat the problems of organ shortage and decrease the chance that a patient’s body will reject it, researchers have been working to create synthetic organs from patients’ own cells. Now a team of scientists from Massachusetts General Hospital and Harvard Medical School has gotten one step closer, using adult skin cells to regenerate functional human heart tissue, according to a study published recently in the journal Circulation Research.
