Cellectis Community Guidelines Our Cellectis Community, which consists of Twitter, LinkedIn and Facebook channels, was created to allow Cellectis to interact with the public and share information about the company and/or other relevant information regarding the space we work within. We’ll do our best to talk candidly about the topics that are important to you, listen to your feedback, answer your questions and be transparent about sharing information and providing our perspective. Our company values the importance of open communication and transparency, but we also have to be sure that we comply with the laws that apply to our business and our corporate ethics.
