Hi Anne-Sophie and Vincent, excellent post and congratulations on the launch! My main question is about the growth factors; I've heard that there's a few compounds used in these processes that really don't scale, fetal bovine serum being the biggest one right now. Do you have novel approaches to creating this? How will this scale in the future?

Thanks, best of luck!

Thank you! For the growth factors, we do not have any plans currently for producing them in-house, however there are several companies within the industry (Future Fields for example) that are making great progress in developing animal-free growth factors. Right now, using precision fermentation seems to be the preferred method of production. This is essentially beer brewing but the yeast is modified to produce a certain protein/ growth factor. Since this process is yeast based, it should scale fairly well, as yeast is resistant to the stresses found inside the fermenters.
