Like Samson, researchers in the field of stem cells have used the jawbone to make a point. Dr. Gordana Vunjak-Novakovic and her team at Columbia University have manipulated adult stem cells to grow one of the most difficult sections of bone to replace, the temporomandibular joint. This jawbone was created by allowing pluripotent cells harvested from marrow to grow in a scaffold that was fashioned to mimic the TMJ’s shape.
It is the first accurate and anatomically sized bone created by stem cells in a lab. Dr. Vunjak-Novakovic hopes that this new creation will serve as a proof of concept
Each one of us receives approximately 60 new mutations in our genome from our parents.
This striking value is reported in the first-ever direct measure of new mutations coming from mother and father in whole human genomes published today.
For the first time, researchers have been able to answer the questions: how many new mutations does a child have and did most of them come from mum or dad? The researchers measured directly the numbers of mutations in two families, using whole genome sequences from the 1000 Genomes Project. The results also reveal that human genomes, like all genomes, are changed
