Researchers discover that a 'muscle' cancer is not really a muscle cancer

(St. Jude Children's Research Hospital) St. Jude Children's Research Hospital oncologists have discovered the cell type that gives rise to rhabdomyosarcoma, the most prevalent soft tissue cancer in children. Previously, scientists thought the cancer arose from immature muscle cells, because the tumor resembled muscle under the microscope. However, the St. Jude researchers discovered the cancer arises from immature progenitors that would normally develop into cells lining blood vessels.
