Scientists seeking new ways to fight maladies ranging from arthritis and osteoporosis to broken bones that won’t heal have cleared a formidable hurdle, pinpointing and controlling a key molecular player to keep stem cells in a sort of extended infancy. It’s a step that makes treatment with the cells in the future more likely for patients.
Controlling and delaying development of the cells, known as mesenchymal (pronounced meh-ZINK-a-mill) stem cells, is a long-sought goal for researchers. It’s a necessary step for doctors who would like to expand the number of true
