Description: 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 progenitors. 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. Gentaur offers CD34+ Progenitor Cells from the cord blood of healthy donors, produced at Gentaur's cell culture facility. 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.Immediately after isolation, the freshly prepared CD34+ Progenitor Cells are cryopreserved using Gentaur's proprietary serum-free freezing medium, Cryo-SFM. Each cryo vial contains more than 100,000 viable cells after thawing.

Description: CD133 (Prominin-1) is a glycoprotein with sub-cellular localization in plasma membrane protrusions. In humans, this protein was originally identified as an antigenic marker expressed on hematopoietic stem cells. In addition,CD133 is also expressed by neural and muscle progenitor cells. CD133+ cells are isolated in Gentaur's facilities from fresh cord blood. These cells are highly proliferative primitive progenitors. They can give rise to mature, terminally differentiated blood cells by means of directed differentiation. Gentaur also provides suitable expansion and differentiation media. Immediately after isolation, the freshly prepared CD133+ Progenitor Cells are cryopreserved using Gentaur's proprietary serum-free,animal component-free and defined freezing medium Cryo-SFM. Each cryo vial contains more than 100.000 viable cells after thawing.
