Sequencing and single-nucleotide polymorphism (SNP) karyotyping of in vitro MDS samples. (a) Mutational analysis of day 0 BM total nucleated cells or CD34+ cells and hCD45+ cells retrieved after LTC (MSCs and/or MS5; patients n=6; ‘-’ not available). (b) SNP karyotyping showing the maintenance of MDS48 clonality between pre- and post-culture. Presence of a trisomy-8 subclone (see red arrow) in both day 0 and post culture on MS-5.
