Differentiation of hMSC into mature adipocytes takes approx. 2 weeks. You can keep the adipocytes for up to 3 weeks in the MSC Adipogenic Differentiation Medium. After 3 weeks we recommend to switch to PromoCell's Adipocyte Nutrition Medium (C-27438).

Changing the medium every 2-3 days, the neuronally differentiated MSC can be kept in culture for up to 2 weeks.

Human Mesenchymal Stem Cells have retained the ability to differentiate into a variety of cell types including fat cells, chondrocytes, and osteoblasts. PromoCell supply hMSC from 3 different tissues: bone marrow (hMSC-BM; C-12974), umbilical cord matrix (hMSC-UC; C-12971), and adipose tissue (hMSC-AT; C-12977).

MSC-BM show very good differentiation into bone cells but also into chondrocytes and fat cells when the respective Differentiation Media is used.
MSC-UC have a high potential to differentiate into chondrocytes but only weak potential for fat or bone cell differentiation.
In contrast, MSC-AT differentiate very well into fat and bone cells but only moderately into chondrocytes.

In other words, to obtain a high percentage of bone cells, MSC-BM or MSC-AT are the cells of choice. There are of course lot-to-lot variations and the differentiation will decrease from passage to passage. If you need MSCs with a particularly high osteoblast differentiation capacity, you can contact our Scientific Support before placing your order so that we can select an appropriate cell lot for you.

The population doubling times for PromoCell hMSC (hMSC-BM, hMSC-AT, hMSC-UC) are typically ≤ 30 hrs when using Mesenchymal Stem Cell Growth Medium 2 (C-28009). If you seed the hMSC at 4.000 cells/cm², it will take between 4-7 days until they reach subconfluency.

Our MNC lots are checked for the rate of lymphocytes, monocytes and granulocytes w/o staining by FSC/SSC using a flow cytometer. A sample plot is attached. For our purified CD14⁺ monocytes we additionally perform a CD14⁺ staining.

It takes 7-8 days to generate fully mature myeloid dendritic cells.

According to our experience, they can be maintained for 3 to a maximum of 7 days. However, the morphology will change and they will look more and more "degenerate".

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.
