Condition group
Histiocytic and dendritic cell disorders
Conditions of the immune cells that normally clear away debris and infection, when too many are made or they behave wrongly.
Conditions in this group
Grouped by the part transplant usually plays. Treatment depends on the exact diagnosis, disease stage, prior treatment and the person’s health.
Donor transplant option 1
A transplant using a donor’s blood-forming cells is an established option for selected patients. A team may consider relatives, unrelated registry donors or cord blood, depending on the circumstances.
Limited transplant role 1
Other treatments are usual. Transplant may be considered in selected circumstances or research settings, as described on the condition page.
Other condition groups
Understanding transplant
Understanding can become action.
Some patients need a blood stem cell donor. Others receive different treatment. Wherever your interest began, you can help more people find the donor they need.
Join the registry
JBF points you to the official registry that serves your country. It explains who can join and what donation involves.
Help someone you love find a donor
If someone you love needs a donor, our family guide explains practical ways to help. A registration drive can add many potential donors at once, for them and for others.
Support this work
Gifts to the Jada Bascom Foundation support donor-awareness education like this page, community outreach, drive planning and referrals to official registries.
