Happy World Marrow Donor Day! Today we celebrate blood stem cell and marrow donors. People who give of themselves to save the life of a complete stranger. People like Guille Henegar who joined the registry at a swabbing event while a student at Denison University in Granville, Ohio. After graduating Guille received the call he was a match and went on to donate his stem cells. Thank you Guille for swabbing, answering the call, and donating. You are a life saver! 🌏💚 #WMDD #worldmarrowdonorday #lifesavers
