Whether you've got Filipino ancestry or not, it's worth signing up for the National Bone Marrow Registry. It's free and easy to register, and you can often be typed along with a blood donation. (That's how I got in the registry several years ago.) There's a joint blood drive and marrow donor registration drive happening at Cornell's Bartels Hall on Tuesday, February 21st.
You can find out more at www.marrow.com or e-mail firstname.lastname@example.org to ask for an organization near you that can get you in the registry.
If you're of Filipino ancestry, it might be especially important for Christine's sake to look into this now. And if you're not, you could potentially help someone else. There's no obligation to donate bone marrow even if a match comes up. If you're in the registry and you're a potential match for someone who needs a bone marrow transplant, they will contact you to discuss the options.
