“…12 The erythroid lineage carried the same RAS alteration as the respective myeloid cells, confirming the clonal origin of erythropoiesis in JMML. 4,32,33 In two of the three patients with EBV B cell lines studied, B lymphocytes had wild-type RAS and -in the case of the patient with monosomy 7 -normal karyotype. Like EBV B cells, CD3 + T lymphocytes carried wild-type RAS and polyclonality of B and T lymphocytes was confirmed by X-chromosome inactivation analysis.…”

“…Thus, Inoue et al [25] used cytogenetic data of patients with JCML to demonstrate the presence of the same karyotypic abnormality (monosomy 7) in both initial marrow specimen and pooled erythroid colonies, suggesting erythroid involvement in the malignant JCML cell clone in addition to the monocyte-macrophage lineage. Lau et al [16] described a case of JCML terminating in Blymphoid blast crisis.…”

“…The six previously unpublished patients in this report fit the classical clinical and laboratory description of JCML [13,14] and showed the characteristic in vitro hallmarks alluded to in the introduction. They were designated as patients [21][22][23][24][25][26] to correspond with our ongoing series. Details on the other patients in the series can be found as follows: patients 1-9, [1][2][3][4][5][6][7]; patient 10, [8]; patients 11-16, [9]; patient 17, [16]; and patients 18-20, [17].…”

“…Bir kromozom işaretleyici ile kolonilerinin sitokenetik analizi sonucu eritroid, monositik ve makarofaj hücrelerine farklılaşma yeteneğine sahip erken progenitör hücrelerden JMML geliştiği öne sürülmektedir (57,58). Bu klonal bozukluk sonucunda JMML'de eritroid serinin etkilenmesi, alfa ve gama globülin genleri, eritropoetin reseptör ekspresyonu ve GATA-1 ekspresyon artışı gözlenerek doğrulanmıştır (59).…”

“…JMML'nin klonal doğası farklı serilerde de gösterilmektedir. Öncelikle az sayıda ki JMML'li hastanın kemik iliğinde sitogenetik markırların varlığı klonaliteyi göstermektedir (57). Bu hastalığa sahip kız hastalarda X kromozomunun inaktivasyonu önemli bir klonal paterni oluşturmaktadır (35).…”
