Here, we present human pluripotent stem cell (hPSC) culture protocols, used to differentiate hPSCs into CD34+ hematopoietic progenitors. This method uses stage-specific manipulation of canonical WNT signaling to specify cells exclusively to either the definitive or primitive hematopoietic program.

An ex vivo protocol to generate mature human red blood cells from hematopoietic stem/progenitors is described. Additionally we describe an efficient lentiviral-delivery method to knockdown the transcription factor TAL1 in primary erythroid cells. The efficiency of lentivirus mediated gene delivery is demonstrated using GFP expressing viruses.

The colony forming cell (CFC) assay is an in vitro assay in which hematopoietic progenitors form colonies in a semi-solid medium. A combination of colony morphology, cell morphology, and flow cytometry are used to assess the ability of the progenitors to proliferate and differentiate along the different hematopoietic lineages.
FAQs
The process is controlled by coordinated changes in gene expression, transcription factor activity, and signals from the bone marrow microenvironment. These inputs progressively restrict which developmental programs a stem or progenitor cell can follow, thereby guiding commitment toward erythroid, myeloid, or lymphoid fates. Their interaction explains how one starting cell population can generate distinct blood-cell lineages.
Signals from the bone marrow microenvironment help shape hematopoietic outcomes by influencing the decisions made during progressive lineage commitment. Their importance is that differentiation does not depend only on the starting stem or progenitor cell; surrounding conditions also guide whether development proceeds toward erythroid, myeloid, or lymphoid fates. This makes the microenvironment a central subject in biology and disease research.
These developmental branches produce cells with different roles in the body. Erythroid differentiation supports oxygen transport, while myeloid and lymphoid differentiation contributes to immune defense and other blood functions. Hematopoietic differentiation research therefore connects lineage decisions with the maintenance of essential physiological processes, helping investigators relate changes in blood-cell development to broader biological outcomes.
Disrupted lineage commitment can help explain how abnormalities arise in anemia, leukemia, and immune disorders. Studying changes in gene expression, transcription factor activity, or microenvironmental signals provides a way to examine how normal blood formation is altered. This disease-oriented perspective makes differentiation a useful framework for connecting cellular development with pathological blood and immune conditions.
A hematopoietic differentiation model provides a research framework for examining stem cell biology, blood development, and the progression of progenitor cells toward distinct lineages. Investigators can use these models to study how developmental signals and regulatory changes relate to erythroid, myeloid, or lymphoid outcomes. The resulting information supports comparisons between normal blood formation and disease-associated abnormalities.
Because the process links stem and progenitor cells with defined blood-cell lineages, its study can inform research on potential cell-based therapies. Models help investigators examine blood development and determine how developmental programs relate to desired cellular outcomes. This application extends hematopoietic differentiation beyond basic biology, connecting lineage research with efforts to understand therapeutic possibilities.
