Our bodies are made of many types of cells, each with a specific purpose. Early on in development, however, cells haven’t been assigned a “purpose” yet. These early cells are called stem cells – and they serve an important purpose. Stem cells are the building blocks of the human body. They can continually renew and make more of themselves, and they can become cells with specialized functions.
Stem cells collected from CMT patients are an important tool for CMT research. They can be turned into neurons and glia, cell types that are affected by CMT disease. If we can study these cells, we can increase our understanding of CMT and test the effectiveness of new treatments more quickly.
Stem cells can be used to advance the understanding and treatment of CMT in three ways:
- Disease research: Study how cells affected by CMT develop and dysfunction, and how that might vary.
- ‘Clinical trials in a dish’: Test drugs to identify the safest and most promising options for future clinical trials.
- Cell replacement therapy: Generate cell types that are affected by CMT, correct their dysfunction, and use these new cells to replace the damaged or dead ones in the patient’s body.
CMTA is investing in the creation of new stem cells lines to cover more types of CMT and ensure we have representation from both sexes. We need adults from the CMT community who have specific types of CMT to volunteer to donate a small blood sample and a small skin sample. Check below for the list of CMT types we need.
Partner NYSCF
CMTA is working with the world-renowned New York Stem Cell Foundation (NYSCF) on this project. Our joint mission is to accelerate cures for CMT. NYSCF’s independent laboratory is a non-profit accelerator that reduces the cost, time, and risk of developing new treatments and cures. NYSCF uses samples from CMT patients to create stem cells and stores and shares samples and cells with CMTA’s researchers worldwide to help us accelerate the development of treatments.
What is Involved?
Participation involves providing samples (small amount of blood, a very small skin sample, and a saliva sample) and health information. Sample collection will be at a NYSCF site in Manhattan, New York USA. Alternatively, at-home or local collections can also be arranged (within the USA) if travel is a barrier to participation. You will need to be able to provide your genetic test report showing one of the specific mutations listed below. Due to the requirements of the collection process, we can only accept applications from persons living within the USA.

How do I take part?
Please follow the link below to the expression of interest form. The expression of interest should take no more than 5 minutes to complete. Completion of the expression of interest form does not commit you to taking part in the study or guarantee that you will be eligible to participate.
If selected, you will be contacted by NYSCF who will confirm your information, determine eligibility, and provide full details about the study procedures. If you decide to participate, NYSCF will ask you to sign a consent form and arrange your sample collection.
Details provided on this form will be accessed only by CMTA staff and NYSCF staff involved in this study. By completing this form, you are allowing CMTA and NYSCF staff to securely view and store your information and contact you for the purposes of this study.
We may not be able to contact non-selected applicants due to the volume of applications, but we are hugely grateful for your interest in this study.
UPDATE AS OF DECEMBER 2024
This opportunity has now closed. CMTA has a growing collection of 17 stem cell lines and 2 isogenic controls available for research. We thank all members of the community who have donated to enable the creation of this collection for “disease in a dish” studies. The cell lines were made directly from small skin biopsies or blood samples donated by CMT patients. The donor samples were converted to stem cells at the New York Stem Cell Foundation (NYSCF) using the highly innovative induced pluripotent stem cell (iPSC) technology, whose significance has been recognized with a Nobel Prize. iPSCs are powerful tools for studying diseases because 1) they have the genetic profile of a patient with CMT, 2) they can be maintained indefinitely and used for many studies, and 3) they can be converted to cell types in the body that are relevant to the disease process. Thanks to our volunteers, 34 drug developers and research groups around the world have thus far used these cell lines for their CMT studies.
Thank you, again, for participating in this critical study. CMT research cannot progress without your participation. We look forward to your continued participation in future studies and trials. Details of all currently open opportunities can be found on CMTA’s website on the Patients as Partners in Research page.
