Scientists discover stem cell origin of neck and shoulders

ffolds of connections early during embryonic development which are later embellished and filled by other cells: just like the scaffold of a house which is later filled in by bricks, mortar and windows. If cells are from the same stem cell origin they 'stick together' throughout their life ?normally without us noticing it."

As the joining points between muscles and bones have survived unaltered across hundreds of millions of year researchers can also start to map cell territories into fossils. For the first time the research team have been able to trace what happened to a major shoulder bone that features in many extinct land animals. They found that it appears to survive in modern vertebrates as the scapular spine.

Dr Koentges commented, "Now that we have identified these key players in forming the neck and the shoulders we can start looking for the genes that are on in these stem cells and which are ultimately responsible for evolutionary changes over millions of years and are also behind a number of serious human illnesses. This is an active area of research that we are involved in."
