Scientists Can Now 3D-Print The Building Blocks of Life

Scientists have developed a 3D-printing method capable of producing highly uniform blocks of embryonic stem cells. These cells are capable of generating all cell types in the body and could be used as the ‘Lego bricks’ to build tissue constructs, larger structures of tissues, and potentially even micro-organs. They could also be used for stem cell regulation and expansion, regenerative medicine, drug screening studies, and potentially even for the construction of micro-organs. “It was really ...

Kidney created from stem cells

Harvard Stem Cell Institute (HSCI) principal faculty at Brigham and Women’s Hospital (BWH) have established a highly efficient method for making kidney structures from stem cells derived from skin taken from patients. The kidney structures formed could be used to study abnormalities of kidney development, chronic kidney disease, and the effects of toxic drugs, and could be incorporated into bioengineered devices to treat patients with acute and chronic kidney injury. In the longer term, these me...

Stem Cells Used to Strengthen Babies’ Bones in the Womb

The first clinical trial injecting fetal stem cells into babies in the womb will start in January and will be led by Sweden's Karolinska Institute and in the UK by Great Ormond Street Hospital. The stem cells will come from terminated pregnancies. It is hoped the cells, which are able to transform into a range of tissues, will lessen symptoms of incurable brittle bone disease. Severe brittle bone disease is rare but can be so devastating that many women decide to end their pregnancy on being ...

Tension helps heart cells develop normally in the lab.

Stanford researchers Beth Pruitt and Alexandre Ribeiro have discovered that a heart cell matured from stem cells in the lab looks and behaves like a normal adult heart cell when grown in a long, thin shape and on a surface that provides some tension. Pruitt and her colleagues at the Stanford University School of Medicine began working on the problem of how to develop more normal looking heart cells through a Stanford Bio-X grant in 2010. At the time, their goal was to find ways of probing the me...

Miniature human kidney grown in a dish.

Miniature human kidneys have been grown in a Petri dish using stem cells as the starting point, report scientists in Australia. The mini-kidneys, measuring up to 1cm, were the equivalent of the developing organ in a 13-week-old foetus. The team say the findings, published in the journal Nature, could lead to new ways of testing drugs and eventually a way of replacing damaged kidneys. Experts said there was still a long way to go. The scientists were mimicking the process that takes place insi...

Kidney Transplant Breakthrough

Yokoo and his team who have found a way to grow a full-sized kidney using stem cells. The American Cancer Society estimates there will be 61,000 new cases of kidney cancer in the United States this year. About 14,000 Americans will die from the disease in 2015. Kidney cancer is rare in people under the age of 45. The average age in the United States for diagnosis is 64. Still, there are more than 100,000 people in the United States awaiting kidney transplants, according to the National Kidney...
