Isolation of Murine Embryonic Hemogenic Endothelial Cells

2016
Hematopoietic stem and progenitor cells (HSPC) derive from specialized (hemogenic) endothelial cells during development, yet little is known about the process by which some endothelial cells specify to become blood forming. We demonstrate a flow-cytometry based method allowing simultaneous isolation of hemogenic endothelial cells and HSPC from murine embryonic tissues.

This protocol describes the in vivo reprogramming of mouse cancer cells into type 1 dendritic-like cells within the tumor microenvironment through enforced expression of the transcription factors PU.1, IRF8, and BATF3.
FAQs
Mechanical disruption opens or loosens the tissue structure, while enzymes target extracellular-matrix components and cell–cell attachments. Using both actions can release cells more effectively than relying on a single type of treatment, but the balance must remain controlled. This complementary approach supports recovery of cells suitable for later filtering, counting, culture, or characterization.
Digestion time, temperature, and handling are critical because they influence whether liberated cells remain viable and functionally useful. Excessive or poorly controlled treatment may compromise the quality of the recovered population, whereas insufficient processing may leave cells within the matrix. Maintaining appropriate conditions helps preserve both cellular function and a representative mixture of cells.
These structures hold cells within intact tissue, so their controlled breakdown determines how completely cells can be released. The extent of breakdown affects which cells enter the recovered preparation and whether those cells remain suitable for downstream analysis. This is especially important when the goal is to study tissue-derived populations rather than a selectively altered subset.
Once individual cells are released, the preparation can be filtered, separated, counted, and directed to culture or molecular and microscopic characterization. The sequence depends on the intended use. These downstream operations convert a tissue sample into measurements or experimental material for assessing cell number, cellular features, viability, and other properties relevant to the study.
It supports tissue-based diagnostics, primary cell culture, disease modeling, drug evaluation, and regenerative research. Each application uses recovered cells differently: diagnostic and characterization workflows examine cellular features, whereas culture and modeling workflows maintain cells for further study. The process therefore connects tissue samples with both analytical investigations and experiments involving living, tissue-derived cells.
A representative recovered population helps ensure that findings reflect the original tissue rather than only the cells most tolerant of processing. Careful control of digestion and handling supports this goal while maintaining viability and cellular function. That consideration strengthens tissue-based analyses and improves the relevance of cells used in culture, disease modeling, drug evaluation, or regenerative research.
