On to the blocks were poured a mixture of recombinant human bone morphogenic protein (BMP) powder — a genetically engineered protein that causes cells to ossify or become bone — and liquid bone marrow containing stem cells. (newscientist.com)
During development, purkinje cells in the cerebellum, vital for movement, initially formed a multitude of connections, many of which were later pruned away by bone morphogenic protein 4 (BMP4), a protein normally associated with bone growth and healing. (newscientist.com)
A team of researchers from DuPont added so - called morphogenic genes — known from basic research to promote the production of embryonic tissue — to the other genes being transformed (in this case to express green fluorescent protein as a marker of transformation). (sciencedaily.com)
