There is a variety of sources from which to get MSCs or ECFCs including bone marrow, adipose tissue, cord blood, etc.
It is necessary to get both types of progenitors from the same source to directly compare the involvement of the different cell types in processes like tissue and vessel regeneration or contribution to tumor progression.
The ease with which to isolate and subsequently study autologous pairs of ECFCs and MSCs from the same donor makes this method ad...

isolation and animal serum free expansion of human umbilical cord derived mesenchymal stromal cells (mscs) and endothelial colony forming progenitor cells (ecfcs)

The umbilical cord is a rich source for progenitor cells with high proliferative potential including mesenchymal stromal cells (also termed mesenchymal stem cells, MSCs) and endothelial colony forming progenitor cells (ECFCs). Both cell types are key players in maintaining the integrity of tissue and are probably also involved in regenerative processes and tumor formation.
To study their biology and function in a comparative manner it is important to have both cells types available from the same donor. It may also be beneficial for regenerative purposes to derive MSCs and ECFCs from the same tissue.
Because cellular therapeutics should eventually find their way from bench to bedside we established a new method to isolate and further expand progenitor cells without the use of animal protein. Pooled human platelet lysate (pHPL) replaced fetal bovine serum in all steps of our protocol to completely avoid contact of the cells to xenogeneic proteins.
This video demonstrates a methodology for the isolation and expansion of progenitor cells from one umbilical cord.
All materials and procedures will be described.
