Efficient transport of assimilates from leaves and stems to developing spikelets is required for better grain filling and high yield.
We triangulated qualitative and quantitative data regarding students' beliefs about Studio STEM to develop a deeper understanding of their motivation and engagement.
Stems needed to develop structures similar to those normally found only in leaves.
At this point the idea was to take a cell, like a skin cell, make it sort of reverse its development and turn into a stem cell, then direct that stem cell to develop into a different kind of cell, like a nerve cell.
Many scientists say, however, that adult stem cells are of limited value to researchers because they are less able than embryonic stem cells to develop into other kinds of cells, like skin or bone tissue, and do not multiply as readily.
The rest are still growing and may not prove useful to scientists who hope to use stem cells to develop replacement body parts.
A later goal will be to use stem cells to develop models of human disease, meaning cultures of cells that can be studied in the laboratory.
A team at the National Institutes of Health has been able to use mouse embryonic stem cells to develop neurons that produce dopamine, a brain chemical that is depleted in patients with Parkinson's disease.
A debate over the ethics of the research was fueled Thursday after South Korean scientists reported that they had cloned a human embryo, then culled the stem cells to develop therapeutic treatments.
Guiding stem cells to develop into muscle cells only is also a difficult task.
