The above mentioned equation for estimating [P.sub.(k)] can be derivate with respect to k donors in order to estimate the number of additional donors required to increase by 1% the expectative of finding a donor with complete or partial HLA match for a q recipient in the waiting list.
"Once we found an HLA match, we implanted the embryo into the mother's uterus.
Screening was also undertaken to see if the embryo would be an HLA match to determine whether it may develop into a suitable stem-cell donor for the sibling with thalassemia.
Both variables were significantly associated with increased numbers of available donors (P = 0.01 for the increase in the fraction of cells that survive storage and thawing and P < 0.0001 for degree of HLA match).
(227) Even if a full ban were implemented, parents could elect to reproduce naturally and continuously until one of the naturally conceived children proved to be a strong HLA match with the ill sibling.
(9) In light of the fact that the patient's donor was haploidentical, a perfect 10 out of 10 HLA match; it has also been shown that non-myeloablative therapies have shown decreased transplant-related mortality.
