MDS-LGF cell line is a blastic subline originated from MDS-L. (MDS-L cell line is a blastic subline derived from MDS92 which was established from the bone marrow of a patient with MDS.) MDS-LGF cells proliferate without IL-3 and have lost maturing capacity.

Regarding MTA between user institutions and RIKEN BRC, there are two kinds of MTA, not-for-profit academic purpose (C-XXXX) and for-profit research purpose (C-XXXXp) , depending on the sort of user institutions and the purposes of use. Please use an appropriate MTA(to see). In relation to commercial use and use for patent filing, first of all Please contact RIKEN BRC (cellbank.brc@riken.jp).
splice donor site mutation of TP53 (c.672+1G>A; homozygous; COSM6906) NRAS (G12A) mutation (heterozygous; COSM565) CEBPA (Q311stop) mutation (heterozygous; COSM29221) HIST1H3C : wild type in all the cells
細胞寿命
infinite
細胞形態
lymphocyte-like
分化機能特性
Whole cells retain immature blastic features and differentiation-induction is successful at present.
その他要求性
IL-3-independent, but the addition of IL-3 prmotes cell growth.
As a reference, the main karyotype of the parental MDS-L cell line is: 49, XY, +1, der(5)t(5;19), -7, +8, -12, der(13)t(7;13), der(14)t(12;14), der(15)t(15;15), -17, +19, +20, der(21)t(15;21), der(22)t(11;22).
