...cer in a big way," Van Zant said. "This is a great example of translational research ?from the most basic type of genetic research all the way to possible treatments for patients." One big obstacle chemotherapy patients face is stem cell loss after treatments. This limits the dosage amount and types of ch...

...re actually needed. With production in leaves, for example - or with conventional production methods - such lengthy storage is not possible: the protein must be isolated immediately after production. So, production in plant seeds provides the clear advantage of timely processing. High production of an ef...
