Erythroid differentiation of human induced pluripotent stem cells is independent of donor cell type of origin

ABSTRACT: Epigenetic memory in induced pluripotent stem cells (iPSCs), with regards to their somatic cell type of origin, might lead to variations in their differentiation capacities. In this context, iPSCs from human CD34+ hematopoietic stem cells (HSCs) might be more suitable for hematopoietic differentiation than commonly used fibroblast-derived iPSCs. To investigate the influence of an epigenetic memory on the ex vivo expansion of iPSCs into erythroid cells, we compared iPSCs from human neural stem cells (NSCs) and human cord blood-derived CD34+ HSCs and evaluated their potential for differentiation into hematopoietic progenitor and mature red blood cells (RBCs). Although genome-wide DNA methylation profiling at all promoter regions demonstrates an epigenetic memory of iPSCs with regards to their somatic cell type of origin, we found a similar hematopoietic induction potential and erythroid differentiation pattern. All human iPSC lines showed terminal maturation into normoblasts and enucleated RBCs, producing predominantly fetal hemoglobin. Differences were only observed in the growth rate of erythroid cells, which was slightly higher in the CD34+ HSC-derived iPSCs. More detailed methylation analysis of the hematopoietic and erythrocyte promoters identified similar CpG methylation levels in the CD34+ iPSCs and NSC iPSCs, which confirms their comparable erythroid differentiation potential. To investigate the influence of an epigenetic memory on the ex vivo expansion of iPSCs into erythroid cells, we compared iPSCs from human neural stem cells (NSCs) and human cord blood-derived CD34+ HSCs and evaluated their potential for differentiation into hematopoietic progenitor and mature red blood cells (RBCs). RNA samples for microarray analysis were prepared using RNeasy columns (Qiagen, Germany) with on-column DNA digestion. 300ng of total RNA per sample was used as the input in the linear amplification protocol (Ambion), which involved the synthesis of T7-linked double-stranded cDNAs and 12hrs of in vitro transcription incorporating the biotin-labeled nucleotides. Purified and labeled cRNA was then hybridized for 18hrs onto HumanHT-12 v4 expression BeadChips (Illumina, USA) following the manufacturer's instructions. After the recommended washing, the chips were stained with streptavidin-Cy3 (GE Healthcare) and scanned using the iScan reader (Illumina) and the accompanying software. The samples were exclusively hybridized as biological replicates. 8 samples were analyzed: CD34 1, Human CD34+ Cord blood CD34+ Hematopoyetic Stem Cell(HSC) population 1, 1 replicate CD34 2, Human CD34+ Cord blood CD34+ Hematopoyetic Stem Cell(HSC) population 2, 1 replicate CD34 OSiPS 1, Human Human two factors (POU5F1, SOX2) induced Pluripotent Cell (iPSC) reprogrammed from CD34+ Cord blood CD34+ Hematopoyetic Stem Cell(HSC) induced Pluripotent Cell (iPSC) population 1, 1 replicate CD34 OSKMiPS 1, Human Human four factors (POU5F1, SOX2, KLF4, CMYC) induced Pluripotent Cell (iPSC) reprogrammed from CD34+ Cord blood CD34+ Hematopoyetic Stem Cell(HSC) induced Pluripotent Cell (iPSC) population 1, 1 replicate CD34 OSiPS 2, Human Human two factors (POU5F1, SOX2) induced Pluripotent Cell (iPSC) reprogrammed from CD34+ Cord blood CD34+ Hematopoyetic Stem Cell(HSC) induced Pluripotent Cell (iPSC) population 2, 1 replicate CD34 OSKMiPS 2, Human Human four factors (POU5F1, SOX2, KLF4, CMYC) induced Pluripotent Cell (iPSC) reprogrammed from CD34+ Cord blood CD34+ Hematopoyetic Stem Cell(HSC) induced Pluripotent Cell (iPSC) population 2, 1 replicate H1, Human H1 embryonic stem cell (ESC), 1 replicate H9, Human H9 embryonic stem cell (ESC), 1 replicate

Epigenetic memory in induced pluripotent stem cells, which is related to the somatic cell type of origin of the stem cells, might lead to variations in the differentiation capacities of the pluripotent stem cells. In this context, induced pluripotent stem cells from human CD34(+) hematopoietic stem cells might be more suitable for hematopoietic differentiation than the commonly used fibroblast-derived induced pluripotent stem cells.

Project description:The differentiation capability of induced pluripotent stem cells (iPSCs) towards certain cell types for disease modelling and drug screening assays might be influenced by their somatic cell of origin. Here, we have compared the neural induction of human iPSCs generated from either fetal neural stem cells (fNSCs), dermal fibroblasts or CD34+ hematopoietic stem cells. Neural progenitor cells (NSCs) and neurons could be generated at similar efficiencies from all iPSCs. Whole genome transcriptome analysis and an expression analysis of neural genes in iPSC-derived NSCs revealed a separation of neuroectoderm- from mesoderm-derived cells. Furthermore, we found genes, which were similarly expressed between fNSCs and neuroectoderm- but not mesoderm-derived NSCs. Notably, these neural signatures were retained after transplantation into the cortex of mice and paralleled with increased survival and integration of neuroectoderm-derived cells in vivo. These results indicated distinct origin- dependent neural cell identities in differentiated human iPSCs both in vitro and in vivo. RNA samples for microarray analysis were prepared using RNeasy columns (Qiagen, Germany) with on-column DNA digestion. 300 ng of total RNA per sample were used as the input in the linear amplification protocol (Ambion), which involved the synthesis of T7-linked double-stranded cDNAs and 12hrs of in vitro transcription incorporating biotin-labeled nucleotides.

The samples were exclusively hybridized as biological replicates.
