We have some big news to share, and we’re glad you’re here to read about it!

Today, Cellero has announced that we will officially be joining Charles River. 

This exciting change will complement Charles River’s recent acquisition of HemaCare and allow our company to better serve a growing list of customers and partners across the cell and gene therapy lifecycle. This unified value-added organization will enhance the supply of critical biomaterials, including a wide range of human-derived primary cell types to support the discovery, development, and manufacture of cell therapies.

Our mission is to help all of you — scientists, researchers, engineers, physicians, entrepreneurs — succeed in creating and administering tomorrow’s treatments and cures. Together we can help more people on their journeys to health and wellness.

We look forward to continuing to work with you to fuel your drug discovery and early-stage development needs.


  1. I have an artificial heart valve and take a blood thinner. Do l qualify? I do not want to fill out a lot of paperwork and then be rejected.

    • Hi Tim,
      I think that since you are on blood thinners it would not be a good idea for you to donate. But thanks for considering being a donor. The cells we collect really help researchers in so many different studies.

    • Thank you for your interest Julia. Living in the UK does disqualify you as a blood donor in the US. We would be happy to take you in as a donor for research though. Where are you located? We have donor centers in Memphis, TN; Lowell, MA; Northridge, CA and Puyallup, WA.
