In Japan, because of the very limited number of cadaveric donors in the pediatric generation, a partial graft from a related living donor or a split graft from a cadaveric donor remains a popular modality. Reflecting this background, discussion about the marginal donor for the pediatric age group in Japan includes such factors as graft size, vascular anatomy, transmission of the genetically defined anomalies, HLA matching, and ABO incompatibility, instead of factors common in Western countries. Details are discussed in each.
