The Vena saphena section that we use for HSaVEC isolation originates from the thigh.

Juvenile HDMEC (C-12210) are isolated from the dermis of foreskin. Adult HDMEC (C-12212) are isolated from different regions. The localizations include cheek, temple, breast, upper arm, and labia. Please contact our Technical Customer Support if you need HDMEC from a particular part of the body.

Our HPAEC (C-12241) are harvested directly from the pulmonary artery. For their isolation, the vessel is explanted right after the position where the artery leaves the heart, including the bifurcation. HPAEC represent the innermost cell layer (i.e. the endothelial cells) of the pulmonary artery. We also supply pulmonary microvascular endothelial cells (HPMEC; C-12281) isolated from the capillaries of peripheral lung tissue.

The study of angiogenesis has been significantly advanced by the ability to culture endothelial cells in vitro. Initially, large vessel ECs, such as those isolated from the human umbilical vein (HUVEC) were used for these studies but increasingly it has been recognized that microvascular endothelial cells are a more appropriate model since angiogenesis involves microvessels rather than large vessel ECs.

Our HPMEC are isolated from peripheral lung tissue of adult donors.

Our HUtMEC are isolated from the middle layer of the uterine wall (myometrium). The tissue donors were not pre-treated with hormones.

Our HCMEC (Human Cardiac Microvascular Endothelial Cells) are not endocardial cells. They are isolated from the capillaries in the heart muscle. Therefore, they are in fact microvascular.

The PromoCell DC Generation Media have been developed for the easy and efficient generation of immature as well as fully mature myeloid dendritic cells from peripheral blood monocytes. For freshly isolated mononuclear cells (MNC) and monocytes we recommend our DC Generation Medium XF (C-28052), for cryopreserved monocytes our DC Generation Medium (C-28050). When using DC Generation Medium (C-28050) with fresh MNC, the Monocyte Attachment Medium (C-28051) is needed in a first step for efficient adherence of the monocyte fraction. Please see Instruction Manual, Application Note and the graph below for further details.

Usually, we do not recommend specific plasticware but we have found that with PromoCell’s Dendritic Cell and Macrophage Generation Media, choice of plasticware can have a lot of an influence. For our Dendritic Cell Generation Media we recommend to use tissue culture vessels from BD Falcon^TM.

There is no significant difference in the percentage of cells that will differentiate into Dendritic Cells. But when using cryopreserved cells, the initial cell loss will be higher compared to when fresh cells are used. i.e. the final number of differentiated cells that can be expected will be higher with fresh cells as a starting material due to lower cell death rate.
