As shown in Fig.1, Yoshihara’s study and other three studies71, , –74 actually just observed the increased amounts of CD34+ orCD34+CD133+KDR+ orCD31+CD45+CD34+CD133+ cellsdirectly obtained from PB of MMD patients, and their results were consistent.However, the investigated targets of the studies of Jung75 and Kim76 were “cultured” early EPCs and late EPCs from PBMNCs. This evidence concerns the gene CD34 and multiminicore myopathy.
