Cord Blood
Aplicación
CD34 is a glycosylated transmembrane protein and represents a well-known marker for primitive blood- and bone marrow-derived progenitor cells, especially for hematopoietic and endothelial stem cells. Although the biological functions of CD34 are largely unknown, recent data suggest that CD34 is involved in maintenance of the progenitor cells in a phenotypically undifferentiated state. PromoCell offers CD34+ Progenitor Cells from the cord blood of healthy donors. The CD34+ Progenitor Cells contain two main cellular subpopulations, hematopoietic and endothelial progenitor cells. Therefore, CD34+ Progenitor Cells are suitable for a series of studies, e.g. directed differentiation into more committed types of blood cells and endothelial lineages.
Calidad
Rigid quality control tests are performed for each lot of CD34+ Progenitor Cells. They are routinely characterized by flow cytometry analyzing the viability, cell size, and the presence of significant markers, i.e. CD34. In addition, all cells have been tested for the absence of HIV-1, HIV-2, HBV, HCV, HTLV-1, HTLV-2 and microbial contaminants (fungi, bacteria, and mycoplasma).
Advertencia
Although tested negative for HIV-1, HIV-2, HBV, HCV, HTLV-1 and HTLV-2, the cells – like all products of human origin – should be handled as potentially infectious. No test procedure can completely guarantee the absence of infectious agents.

Receptor targeting of vector particles is a key technology to enable cell type-specific in vivo gene delivery. For example, T cells in humanized mouse models can be modified by lentiviral vectors (LVs) targeted to human T-cell markers to enable them

Do you have any information about the size of these cells? I need a human cell that can be cultured but less than 5 micrometer. Thanks.

I would like to know whether these are CD34+ progenitor cells isolated from cord blood and directly shipped after isolation or whether they are shipped after being cultured.
1 answer-
Yes, these cells are CD34+ progenitor cells isolated from cord blood. PromoCell Blood and Blood Progenitor Cells are cryopreserved directly after isolation (=P0). Customers will receive them cryopreserved. They haven’t been in culture before freezing.
