Dr. Cole, I understand it can be difficult, when administering ACell in hyaluronic-acid suspension, to realize which areas have and have not been treated. Have you considered tainting the suspenion with some non-permanent color, which could serve as a practical marker of treated sites? I'm unsure whether this is practical — i.e., the coloring would have to be non-reactive with the ACell, obvious enough to be seen with the human eye, non-toxic to the patient, and able to vanish of its own accord or by subsequent treatment with another safe compound — but, if it is, it seems to me to be a simple solution to this challenge.
Thank you.
Thank you.
