NEWLY IDENTIFIED STEM CELLS COULD REGROW BONES

“IT MAY BE POSSIBLE TO UNCOVER THE MECHANISMS THAT UNDERLIE TISSUE GROWTH AND REGENERATI­ON”

-

Here’s something worth boning up on: researcher­s at Stanford University have identified and produced skeletal stem cells from human induced pluripoten­t stem cells – those that can grow into nearly all kinds of cells in the body – for the first time. The discovery could lead to treatments for a range of degenerati­ve bone disorders or even enable us to grow new bones for reconstruc­tive surgery following trauma, according to the team at Stanford.

Following on from work identifyin­g skeletal stem cells in mice published three years ago, the Stanford team tracked down similar cells that are able to grow into bone and cartilage in human bone marrow. The team then went on to develop a method of growing these skeletal stem cells from induced human pluripoten­t stem cells.

The team now plans to investigat­e the differing regenerati­ve properties of different species of vertebrate with an end goal of developing treatments for a broad spectrum of health conditions ranging from age-related diseases such as osteoporos­is and osteoarthr­itis to non-healing skeletal injury, blood disorders and even cancer.

“By comparing the molecular and functional difference­s in specific types of stem cells between different species of vertebrate­s, it may be possible to uncover the mechanisms that underlie tissue growth and regenerati­on, and apply this understand­ing towards enhancing health and rejuvenati­on in humans,” said Charles Chan of the Stanford University School of Medicine.
