Abstract
At the single-cell level, stem cells (SC) are cells that have the ability to self-renew again and produce clonal offspring that have the same properties as parent cells and ability to undergo differentiation to all blood cell lines. In terms of their capacity for self-renewal and proliferation, the majority of stem cells are quite diverse (Weissman, 2000) (Bernitz et al., 2016). However, SC self-renewal ability is controlled by a highly orchestrated integration of environmental signals that come from the stem cell niche and happen in a cell-autonomous manner (Bonnet, 2002) (Hsu and Fuchs, 2012).

They developed an enhanced and simplified xeno- and feeder-free cell culture technique for erythroid differentiation of hiPSCs in this study. There are
numerous advantages to using this system, including reduced handling time, lower costs due to low cytokine support and reduced medium consumption based on erythroid output, continuous harvesting of cells over 6 weeks without digestion or purification...

[...] The colony formation test, flow cytometry, microscopy, and hemoglobin analysis were used to track hematopoietic and erythroid differentiation (Bernecker et al., 2019). 2.4 EB suspension model: EBs were stimulated with an 8-cytokine cocktail for 20 days before being dissociated with collagenase. In the three-phase erythropoiesis system, single cells were grown further (Bernecker et al., 2019). 2.5 Characterization of the HCFC: For further digestion, the HCFC were treated with collagenase B (Bernecker et al., 2019).

[...] One type of stem cell that can divide into white blood cells but not red blood cells is the myeloid stem cell(Notta et al., 2016). Unipotent stem cells are distinguished by their limited capacity for differentiation and unique capacity for recurrent division (Notta et al., 2016). Haematopoietic stem cells generate all types of blood cells, including erythrocytes, granulocytes, monocytes, platelets, and lymphocytes (Larijani et al., 2012). 1.3 Types of stem cell: Mesenchymal stem cells are found in a variety of organs (Zakrzewski et al., 2019).
