|Description||A specialized somatic stem cell (SSC) population in the human endometrium, often identified by using the Side Population (SP) technique, is thought to mediate the endometrial regeneration. The Human Endometrial Somatic Stem Cells are established from human endometrial side population cells, specifically from the Epithelial fraction (ICEp; Cat. No. T4107) or the Stromal fraction (ICEs; Cat. No. T4108).
Both cell types retain the ability to undergo osteogenic and adipogenic differentiation in vitro . After adipogenic induction, the cells show lipid accumulation in the cytoplasm and increased expression of lipoprotein lipase (LPL). When under osteogenic induction, the cells stain positive for bonesialoprotein (BSP) and show increased expression of osterix. Furthermore, both cell types are capable of reconstructing total endometrial-like tissue in vivo when transplanted beneath the renal capsule of NOD-SCID mice. The Human Endometrial Somatic Stem Cells serve as a reliable model to test relevant targets for endometrial physiology and pathology.
|Species||Human (H. sapiens)|
|Applications||For Research Use Only|
|Population Doubling Time||Proliferation ceases after about 20 weeks of culture.|
|Donor Gender||Donor Info Not Disclosed|
|Isolation Method||Endometrial Somatic Stem Cells are isolated based on the Side Population (SP) technique- a method that replies on the capability of cells to exclude the DNA binding Hoechst 33342 dye. Cells are labeled and sorted by flow cytometry based on low Hoechst 333.|
|Cell Type||Primary Cells|
|Expression Profile||1) Purity and origin of cells are confirmed by expression of CD9 (epithelial marker) or vimentin (stromal marker) and CD90, CD73 and CD105 (mesenchymal attributes); 2) Undifferentiated status of the cells are confirmed by expression of OCT4, NANOG, GDF3.|
Use of PriCoatTMT25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) is required for cell adhesion to the culture vessels. Grow cells inECM-coated culture vessels unless otherwise specified in the Propagation Requirements below.
The base medium for this cell line is Prigrow IV medium available in ABM, Cat. No. TM004. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (TM999)* to a final concentration of 10%, L-glutamine to 2mM and Penicillin/Streptomycin(G255). Atmosphere: air, 95%; Carbon dioxide (CO2), 5%.

What is the supply procedure?
The frozen vial of cells will be shipped in Dry ice while T25 flasks by themselves are shipped at room temperature.
Does ''Normal" mean undiseased tissue/organ?
How often do I need to change the media?
The media should be renewed every 2-3 days
How should I store frozen vials of primary cells? Can a frozen vial be put back into liquid nitrogen after delivery?
In most cases, a vial of primary cells shipped in dry ice (-70°C) can be placed back into liquid nitrogen and recovered at a later date by rapid thawing. However it is important to note that the viability of some sensitive cell types may be reduced by the temperature shift of such treatment, making recovery more difficult. For this reason, we recommend that cells be thawed and placed into culture as soon after receipt as possible. It is best to minimize storage time at -70°C; as this is only used for shipping the cells. ABM does not warrant the viability of cells stored at -70C after shipments have been received.
What is the recommended storage temperature?
In general, if you received: Live cells: acclimatize for 3-4 hrs at 37C, 5% CO2 and then change media afterwards. Frozen cells: Immediately place cells in liquid nitrogen or dry ice; -180C.
Is it possible to freeze the cells again after thawing?
Unless specified otherwise in the datasheet, primary cell lines may be re-freezed after thawing. However, primary cells are usually not good for multiple passaging and they usually last only for up to 10-12 population doublings. Our primary cells are usually provided at passage 2, therefore they can be passaged for an additional 1-2 passages. For long term use, immortalized cells are preferred.
Why is it important to determine the optimal seeding density?
The seeding density we recommend is for when cells are plated to a new vessel. The optimal seeding density should allow cells to attach to the surface and have room to proliferate. If you seed too little, cells may not attach well to the surface. Seeding density is important as many cells need to be in close proximity for better growth. Cell-cell interactions allow cells to communicate with each other in response to changes in their microenvironment. This ability to send and receive signals is essential for the survival of the cell. In other cases, if the seeding density is too low, cells may attach but a retardation in cell growth is observed. If you seed too high, the cells will attach but there is insufficient room for further proliferation and they will stop replicating.
How many cells are each vial?
The number of cells in a vial is lot-dependent. A Certificate of Analysis stating the cell quantity of the vial will be provided with your order.
